Illegal gold mining continues in Indonesia’s Aceh despite government crackdown pledge
- Residents in different districts across the Indonesian province of Aceh say gold mining activity in the interior of forest areas continues despite the province’s leaders agreeing a crackdown on illegal mining.
- Fuel shortages have been reported at local gas stations, which some attribute to demand from excavators working to unearth gold ore from inside forest areas.
- In August, Mongabay reported that gold miners had encroached in to a crucial reintroduction forest in Aceh for critically endangered Sumatran orangutans rescued from the illegal wildlife trade.
- Environmental advocacy group Walhi says there are more than 1,000 units of heavy equipment working at more than 450 illegal mining operations in Aceh, while a former provincial official said the government is aware of mining in around half of Aceh’s districts.

Ebola outbreak underscores food insecurity crisis in DRC
The recent Ebola outbreak caused by the Bundibugyo strain of the virus has reportedly claimed more than 3,000 lives, and more than twice as many reported cases, in the Democratic Republic of Congo, according to the U.S. Centers for Disease Control and Prevention. At the same time, analysts warn that roughly 26 million people across […]
Gold miners breach a crucial refuge for rescued Sumatran orangutans
- New analysis by Indonesia’s largest environmental pressure group shows illegal goldminers have encroached Indonesia’s Jantho forest reservation, a vital reintroduction site for the charity workers and state biodiversity officials trying to save the critically endangered Sumatran orangutan from extinction.
- Global investors have rushed to buy gold to maintain wealth against inflation and political instability, exacerbated by the Trump administration and Russia’s invasion of Ukraine.
- The total area damaged by goldminers in Indonesia’s Jantho reservation according to satellite analysis exceeds 14 hectares (around 35 acres), equivalent to approximately 20 football pitches.
- A traditional administrator for the Jantho area in Aceh, a semiautonomous province of Indonesia, said 13 local villages had united against mining in the area, and had reported the miners to local authorities.

Indonesia charges 72 over fires as haze chokes Borneo and Sumatra
Indonesian authorities have charged 72 individuals with intentionally igniting forest fires across five provinces on the island of Borneo and four on Sumatra. Fires across both islands have burned nearly 286,000 hectares (about 707,000 acres) of land from January to Aug. 24 alone, according to FireWatch, a satellite-based monitoring tool developed by forest-mapping platform Nusantara […]
Orangutan Day: Here’s where the three critically endangered species stand
Aug. 19 is World Orangutan Day, a day to honor the three species of Southeast Asian great apes, all of which are classified as critically endangered by the IUCN, the global conservation authority. Orangutans were classified into two species: The Sumatran orangutan (Pongo abelii) found in northern Sumatra, Indonesia, and the Bornean orangutan (Pongo pygmaeus), […]
Rescued from traffickers, reintroduced orangutan becomes mother in the wild
- Fieldworkers at the Jantho orangutan release forest in Aceh, Indonesia’s westernmost region, have recorded the 10th birth by orangutans successfully released back into the wild from a charity-run rehabilitation center.
- Indonesia’s forestry minister named the baby Badar, which means a full moon, and highlighted the need for consistent protection of orangutan habitats in Borneo and Sumatra islands, which are home to Indonesia’s three species of orangutan.
- However, a new study on Sumatran orangutan populations published in the September issue of “Global Ecology and Conservation” concluded that surviving populations likely declined by nearly 20% between 2011 and 2023.

Indonesia’s wildfire season surges as haze spreads into Malaysia
- Fires in Indonesia’s West Kalimantan province have sent haze across the border into Malaysia, where worsening air pollution has forced six schools in Sarawak state to switch to online classes.
- Indonesia is entering the peak of its fire season, with West Kalimantan accounting for more than half of the nearly 49,000 hectares (121,000 acres) burned across six priority provinces as of Aug. 9.
- The fires are also threatening biodiversity, including orangutan habitat and rehabilitation efforts in West Kalimantan, while a separate blaze has forced the closure of Bromo Tengger Semeru National Park on the island of Java.
- Authorities have deployed tens of thousands of personnel and dozens of aircraft to fight the fires, but environmental groups say funding cuts and the intensifying El Niño are raising concerns about Indonesia’s preparedness.

Cacao plantations in Liberia encroach into proposed Kwa national park
A cocoa boom in southeast Liberia is wiping out native forests and encroaching into a proposed national park. The would-be Kwa National Park, a dense tropical rainforest, is home to chimpanzees, forest elephants, pygmy hippos and pangolins. Kwa is partly located in Grand Gedeh county, one of the most densely forested regions in southeast Liberia. […]
What makes chimpanzee conservation last? Lessons from Sierra Leone
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. For more than three decades, Willie Tucker has helped care for Sierra Leone’s western chimpanzees and watched the pressures on them change, reports contributor Patricia Sia Ngevao for Mongabay. Tucker, widely known as “Pa Willie,” helped establish Tacugama […]
Flames reach edge of orangutan rehabilitation center, with fire season set to intensify
- A wildfire came within meters of an orangutan rehabilitation center in Indonesian Borneo, forcing emergency firefighting efforts to protect more than 60 rescued orangutans.
- The close call comes as a strengthening El Niño fuels fires across Indonesian Borneo, where prolonged drought and expanding land clearing are driving orangutans from their forest habitat.
- Conservationists warn that repeated fire seasons are undermining years of rehabilitation and habitat restoration work while increasing conflict between displaced orangutans and local communities.
- With fires spreading into Key Biodiversity Areas, experts say better fire prevention and stronger support for frontline conservation efforts are urgently needed.

Protecting primates could protect thousands of other species, study finds
As biodiversity on Earth faces rapid decline, scientists are advocating for a new conservation approach: Save habitat for primates and protect countless other species along with them. For long, conservation efforts and funding have prioritized umbrella species such as tigers and giant pandas on the basis that protecting the vast areas they depend on can […]
How rescued orangutans are rebuilding a new wild population in Sumatra
Sumatra — Fifteen years ago, Jantho Pine Forest Nature Reserve in Indonesia’s western Aceh province, on the island of Sumatra, had no orangutans. Today, it is home to a growing wild population, built almost entirely from rescued and relocated animals. Since 2011, conservationists from the Sumatran Orangutan Conservation Programme have brought nearly 200 Sumatran orangutans […]
Women’s collectives are protecting Nigeria’s gorilla wildlife sanctuary
In the communities surrounding Nigeria’s Afi Mountain Wildlife Sanctuary, women’s conservation collectives are transforming the protection of a biodiversity hotspot that’s home to the critically endangered Cross River gorilla and endangered Nigeria-Cameroon chimpanzee. These collectives, operating in villages such as Ulom, Katabang and Buanchor in southeastern Nigeria, were born from a realization that traditional, male-led […]
Major orangutan study finds Sumatran population fell nearly 20% despite slower forest loss
- A new study estimates the Sumatran orangutan population declined by nearly 20% between 2011 and 2023.
- The researchers found that habitat loss alone cannot explain the declines, pointing to additional threats such as killing, conflict and habitat fragmentation.
- The study is the first comprehensive reassessment of Sumatran and Tapanuli orangutans since a landmark 2016 survey.
- The Forestry Ministry co-authored the study and says it will use the findings to guide conservation policy, marking a contrast with the previous administration’s public claims that orangutan populations were increasing.

Celebrating World Chimpanzee Day
Happy World Chimpanzee Day. On July 14, as the world celebrates one of humans’ closest living relatives, here’s a roundup of recent Mongabay stories about chimpanzees and their world: Chimps at war in Kibale National Park Chimpanzees, like humans, sometimes fight wars with each other. Mongabay contributor Keith Anthony Fabro reported on a chimpanzee (Pan […]
Small-scale farming, logging eclipse megaprojects as top threats to Tapanuli orangutan habitat
- A new study finds that while large-scale development projects have accelerated forest loss in a key orangutan habitat in Indonesia, small-scale agriculture and logging now account for roughly 70% of direct habitat loss.
- Researchers link the increase in clearing of the Batang Toru ecosystem to changing rural livelihoods, commercial banana farming, and widespread abuse of a legal community logging mechanism.
- The findings raise particular concern for Batang Toru’s eastern forest block, where continued habitat loss threatens one of the smallest and most vulnerable subpopulations of the critically endangered Tapanuli orangutan.
- The authors say protecting the species will require tackling both large development projects and the cumulative pressures from small-scale forest clearing, while expanding conservation beyond Indonesia’s formal protected areas.

Can a photo save orangutans?
In Indonesian Borneo, conservation organization KehatiKu is testing a new approach: paying local people to photograph wildlife and upload the sightings through an app. In just one year, the project has collected around 175,000 records. Participants can earn about $6 for a photo of an orangutan, while smaller payments are offered for more common species. […]
Conserving Sierra Leone’s western chimpanzees: Interview with Tacugama’s Willie Tucker
- Habitat destruction, illegal wildlife trade and climate change remain the leading threats to the western chimpanzee population in Sierra Leone.
- Through community livelihood programs including livestock and seed support, conservationists are trying to help reduce dependence on forests and hunting.
- In 2019, Sierra Leone designated the western chimpanzee as the country’s national animal, strengthening public awareness and support for conservation.
- Willie Tucker, camp supervisor of the Tacugama Chimpanzee Sanctuary, spoke with Mongabay about the sanctuary’s work at the forefront of western chimpanzee conservation, as the facility currently cares for more than 100 western chimpanzees, many of which were rescued from private homes.

Lawmakers seek rights probe into Indigenous conflict at Indonesian timber firm
- Indonesian lawmakers have called for a government fact-finding investigation into alleged human rights abuses linked to a long-running land conflict between the Dayak Kualan Indigenous community and timber company PT Mayawana Persada.
- The community says the company cleared customary forests and sacred sites without its consent, while community leaders have faced criminal charges they describe as retaliation for opposing the project.
- The conflict coincides with one of Indonesia’s largest recent deforestation cases, with more than 42,500 hectares (105,000 acres) of forest, including peatlands and orangutan habitat, cleared inside the company’s concession since 2016.
- Indonesia’s human rights ministry says it will investigate the allegations, while lawmakers have urged police to halt criminal proceedings against community members and review the company’s operating permit.

The women leading a quiet conservation revolution in a Nigerian gorilla sanctuary
- Women’s conservation collectives in the communities surrounding Nigeria’s Afi Mountain Wildlife Sanctuary are working to defend the wildlife, forests and rivers in a protected area that’s home to threatened gorillas and chimpanzees.
- Funded by membership dues, these groups carry out patrols, investigate wildlife crimes, and work collaboratively with traditional leadership structures to censure violators.
- One of the groups’ notable successes comes in ensuring that rules aimed at protecting the environment are upheld without bias or favoritism.
- The successes of the pioneering women’s collectives have inspired the formation of similar initiatives in other villages surrounding the sanctuary.

Indonesia driver sentenced over organized crime group trafficking live orangutan
- A court in Sumatra’s East Aceh district court sentenced a 41-year-old farmer to three years in prison after he was found guilty in a wildlife trafficking case linked to international organized crime.
- Court documents show the farmer from East Aceh district accepted a delivery job driving a consignment in a small truck, and that he helped another individual transfer the protected wildlife at a meeting point in North Aceh district.
- Customs officials said they initiated an investigation following a tip from a member of the public. The customs office later said they believed the perpetrators intended to smuggle the animals to Thailand by boat from a small coastal village in Aceh.
- The presence of hornbills and numerous other species showed the animals were sourced from as far as eastern Indonesia, investigators said.

Leaked study warns of irreversible damage from iron ore mine in Guinea UNESCO site
- Ivanhoe Atlantic, a U.S. mining company, plans to mine iron ore in Guinea’s UNESCO-protected Nimba Mountains.
- Mongabay has obtained a copy of the confidential environmental and social impact assessment (ESIA) currently being reviewed by Guinean authorities, which details extensive and irreversible damage to Nimba’s endemic and endangered species and critical habitats.
- The ESIA concludes that the planned mine risks causing “lasting and significant damage” to the adjacent World Heritage Site.
- The document’s findings also indicate the project might be breaching globally recognized environmental and social safeguards that Ivanhoe has publicly committed to.

Before tourists can see bonobos, trackers must earn their trust
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. In Salonga National Park in the Democratic Republic of Congo, researchers and trackers are working to habituate a group of about 60 bonobos. The aim is to help the great apes accept a limited human presence, first for […]
Apes can imagine too
Turns out imagination is not unique to humans. A series of experiments has shown that a language-trained bonobo was able to distinguish real from fake objects and engage in pretend play. Scientists sat down for a “tea party” with Kanzi to understand how the ape would respond to make-believe scenarios. The results have shown that […]
Pulp and paper giant APRIL adds major deforesters as suppliers after revising sustainability policy
- The changes include lowering its deforestation cutoff date to the end of 2020, which allows APRIL to source wood from two companies responsible for some of Indonesia’s largest recent forest losses.
- APRIL says the move aligns with global standards and helps address fibre shortages caused by permit revocations affecting 15% of its wood supply.
- But critics say the changes weaken a longstanding no-deforestation safeguard and have questioned why APRIL selected these two suppliers among Indonesia’s many fibre producers.
- APRIL says its new suppliers will undergo satellite monitoring, compartment-level traceability and annual independent audits, but critics say transparency concerns remain.

Climate-fueled landslides killed an estimated 58 Tapanuli orangutans, study finds
- The study found that landslides triggered by extreme rainfall in November 2025 likely killed about 7% of the estimated global population of Tapanuli orangutans.
- Researchers warned that without swift intervention, the species could face increasingly frequent climate-driven disasters in the future.
- The study only quantified direct mortality from landslides and did not account for deaths caused by canopy collapse outside mapped landslide areas, starvation, injuries or longer-term ecological consequences.
- In a statement to Mongabay, the forest ministry said it “appreciates and is taking into consideration” scientific studies on the Tapanuli orangutan, including research estimating the impacts of floods and landslides on the species.

As human Ebola cases climb in DRC, critically endangered gorillas are at risk
- Gorillas are vulnerable to communicable diseases that infect humans and other nonhuman primates, including the Ebola virus.
- A new Ebola outbreak was announced in the Democratic Republic of Congo in mid-May, but so far, there have been no reported cases of gorilla infection. Previous outbreaks have devastated western lowland gorillas.
- Armed conflict hampers both conservation and efforts to monitor both Grauer’s and mountain gorilla populations in DRC. They also impair the public health response, which has also been seriously impacted by cuts in U.S. funding under the Trump administration.
- Gorillas are highly social animals, which facilitates spread of infectious disease. Infants and females are disproportionately affected, which has serious consequences for recovery of devastated populations.

Environmental group intervenes in lawsuit to help orangutans, tigers in Indonesia
- Indonesia’s largest environmental group, Walhi, has officially intervened in an environmental lawsuit filed by the government against major pulpwood producer PT Toba Pulp Lestari.
- Walhi says the lawsuit overlooks key ecological impacts, such as critical orangutan and tiger habitats, that should also be addressed through court-ordered restoration.
- TPL is one of dozens of companies whose forest-use licenses were revoked after their forest-clearing activities were blamed for exacerbating floods and landslides during torrential rains in late November 2025.
- Walhi is asking that any funds recovered from the lawsuit be directed toward environmental restoration activities on the ground.

Four years to earn their trust: Habituating bonobos in DRC’s Salonga National Park
- In the heart of Salonga National Park, one of Africa’s largest protected areas, researchers are trying to earn the trust of wild bonobos, one of the continent’s most endangered great apes.
- Conservationists say that habituation is a critical tool for protecting the species, allowing scientists to monitor their health, behavior and populations while strengthening long-term conservation efforts.
- As the Democratic Republic of Congo confronts a renewed Ebola outbreak in its eastern region, park officials acknowledge the ever-present risk of zoonotic disease transmission. However, when conducted under strict biosecurity protocols, bonobo habituation offers significant conservation, scientific and ecotourism benefits that outweigh the risks.

Confinement and disinfected bedding: An ape sanctuary in DRC responds to Ebola
- The Lwiro Primates Rehabilitation Center, located in South Kivu in the eastern Democratic Republic of Congo, has gone into lockdown to protect its primates.
- Primatologists say Ebola transmission from infected wild primates to humans has been documented repeatedly but there are no recorded cases of transmission from humans to great apes.
- Emergency plans have also been activated to limit the spread of the virus in the protected areas of the Greater Virunga Landscape, a transboundary area shared among the DRC, Rwanda and Uganda.
- As of May 27, the World Health Organization has already recorded 223 suspected deaths linked to the current outbreak.

Chimpanzees vs. a mega railway
A massive railway project, The Simandou corridor, in Guinea is cutting through one of West Africa’s most important ecosystems. The Simandou corridor is fragmenting forests that are home to the largest population of endangered western chimpanzees, putting their survival at risk. But why is this massive railway project being built? Deep within Guinea’s forests lie […]
In Java, a women’s collective is helping save gibbons through forest-inspired textiles
- A group of women in Indonesia’s West Java province have become skilled printers on fabric using motifs derived from various plant species found in their local environment.
- Last year, Indonesian primatologist Rahayu Oktaviani received an award in recognition of her organization’s work with Java’s silvery gibbon, which included formation of the grassroots printing collective.
- The most recent assessment estimates fewer than 4,500 Javan gibbons remain in the wild, with half of the world’s Javan gibbon population living in the national park contiguous to the site of the Ambu Halimun initiative.

Report alleges élite ties behind logging permits in Cameroon’s Ebo Forest
- A report by a Swiss advocacy group says a timber company logging Cameroon’s Ebo Forest is tied to a wider network of political élites in Yaoundé.
- The company, Sextransbois, is part of a network of logging and agriculture interests owned by prominent businessman Aboubakar Al Fatih.
- Corporate registry documents analyzed by the group show that Sextransbois was incorporated by relatives of President Paul Biya’s eldest son before being transferred to Al Fatih’s half-brother in 2014.
- Environmental groups have accused a number of companies owned by or linked to Al Fatih of breaking Cameroonian law.

Gunmen kill two rangers in latest deadly attack in DRC’s Virunga National Park
Gunmen have killed two rangers in Virunga National Park in the Democratic Republic of Congo, the latest deadly attack in a region roiled by militia violence. Park sources said a heavily armed group opened fire on a control post at Kamuhororo, on the southern shore of Lake Edward inside Virunga, early on May 21. Kasereka […]
Paying people to see wildlife: Inside a $1-per-hectare conservation experiment in Borneo
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Stop telling people to protect wildlife. Start paying them instead. That’s the idea in a new experiment in Kapuas Hulu district, in Indonesia’s West Kalimantan province, which is testing whether conservation can be made to work with local […]
In the Nimba Mountains, a film examines the paradox of mining-funded conservation
- The Nimba mountain range, which lies at the border of Liberia, Guinea and Côte d’Ivoire, is one of the most biodiversity-rich regions of West Africa.
- Home to western chimpanzees and other threatened species, it is also the site of some of the world’s highest-quality iron ore deposits.
- “Overburden,” a film produced by researchers and academics, explores the impact of mining on the Nimba range, and its increasingly close relationship with conservation.

Conservationists fear fires could erase years of orangutan habitat recovery
- Fires have burned part of a restoration site being prepared for orangutan habitat in Indonesia’s West Kalimantan province, raising fears that another severe fire season could undo years of recovery work.
- The restoration project, led by the government, Yayasan IAR Indonesia and local communities, has replanted about 300 hectares (740 acres) with 150,000 trees to help keep critically endangered orangutans out of nearby farms.
- Conservationists say the fires, likely sparked by nearby land clearing for oil palm, spread rapidly through dry peat and scrub vegetation, despite the area still being in the rainy season.
- With severe El Niño conditions forecast later this year, conservation groups warn they lack sufficient resources to fully prepare for another major fire season like the devastating 2015 crisis.

A new documentary film captures rare mountain gorilla behavior
“That might be something that you see in a decade, not in two years of filming,” Tara Stoinksi, CEO of the Dian Fossey Gorilla Fund, tells me. The behavior she’s referring to occurs in mountain gorilla groups, such as a “dominance transfer,” where a younger male silverback takes over leadership from an older male, and […]
Facebook is a hub for illegal wildlife trade, and that’s by design, report says
- Online sales of wildlife products from protected species are booming on Facebook. The platform hosted more than three-fourths of the 22,000 wild animals and their parts known to be sold online between April 2024 and March 2026, valued at $65 million, according to a recent report.
- Researchers found that about 84% of animals for sale on Facebook are banned from commercial cross-border trade under an international treaty. More than half of them were endangered or critically endangered species.
- Facebook’s architecture — its closed groups, anonymous users, content monetization and algorithms that push related content to users — makes it a go-to platform for traffickers, researchers say. The platform’s official policy bars the sale of wildlife, but the volume of animals offered for sale point to poor moderation.
- To combat this massive online trade, experts call for stricter regulation of content on Facebook and other platforms, as well as better oversight and increased collaboration between online platforms and law enforcement.

Endangered Javan gibbon baby born in UK rare species sanctuary
A rare Javan gibbon was born at a wildlife park in the U.K., one of the world’s main centers for the species’ captive breeding. Lima, now just over 2 months old, is a potential candidate for returning to the species’ native habitat on the Indonesian island of Java. The Javan gibbon (Hylobates moloch), known locally […]
Amid conflict and poaching, tech helps boost mountain gorilla numbers
- Mountain gorillas face serious threats as they lose habitat and are stalked by poachers, but populations have jumped by 73% since 1989, now numbering an estimated 1,063.
- A mobile tool called SMART is helping forest guards and conservationists collect data to better track and protect the apes and other wildlife.
- But budgets are tight; more staff, field equipment and data collection devices are needed, conservation experts say.
- The current security situation across the transborder region between Rwanda, Uganda and the Democratic Republic of Congo is a significant concern, both for forest rangers and gorillas.

To tackle trafficking in gibbons, experts probe what drives demand
- As gibbon trafficking reaches record highs, conservationists say reducing demand is critical to tackling the illegal trade.
- But motivations for wanting to buy a gibbon vary widely between buyer communities, which means the solutions must be tailored accordingly, experts say.
- Surveys of people who voluntarily surrendered gibbons to a sanctuary in Malaysia found that most cited as motivation a love of animals or desire for their children to have an animal to play with.
- In India, by contrast, a sanctuary manager says gibbons are coveted as status symbols, and most arrive at the center via confiscation rather than voluntary submission.

Studying the world’s largest gathering of forest elephants with sound and field observation
- At Dzanga Bai in the Central African Republic—one of the few places where forest elephants gather in large numbers—researchers can observe behaviors that are otherwise difficult to document in dense rainforest.
- Ivonne Kienast leads long-term research combining direct observation with acoustic monitoring, building a detailed record of elephant behavior, social structure, and change over time.
- Her work highlights how sustained presence, local collaboration, and incremental data collection shape understanding of both elephants and the broader forest system they inhabit.
- Kienast spoke with Rhett Ayers Butler, Mongabay founder and CEO, and David Akana, director of Mongabay Africa, over two weeks of conversations in the Central African Republic and the Democratic Republic of the Congo during March 2026. Her responses have been edited and consolidated.

Chimp ‘civil war’ follows rare community split in a Ugandan national park
- A 30-year study documents a rare split within a chimpanzee community in Uganda’s Kibale National Park — one that sparked a deadly war.
- Two rival chimp groups have staged coordinated raids that killed both adult males and infants.
- Researchers recorded at least 24 attacks between 2018 and 2024, suggesting unusually intense violence.
- The findings show how shifting social ties can fracture animal societies and trigger collective violence.

A chimpanzee’s rhythmic drumming with floorboards hints at origins of instruments
- A captive chimpanzee in Japan spontaneously ripped floorboards from a walkway and used them as instruments to perform structured, rhythmic drumming displays while vocalizing
- Researchers recorded 89 performances and found the drumming wasn’t random and followed a structured, rhythmic pattern similar to chimpanzee vocal calls.
- The chimp displayed play faces and what appeared to be laughter while drumming, suggesting the behavior was emotionally rewarding, not just a social display.
- The findings support the hypothesis that instrumental music may have evolved from vocal emotional expression, though the study is limited to a single individual in a captive setting.

See an orangutan, take a photo, earn some money: A viable conservation model?
- KehatiKu, a conservation program in Indonesian Borneo, pays citizen observers to document wildlife sightings and upload them via an app.
- Payments vary by species, with the highest rate, around $6, paid for verified orangutan sightings. Dedicated observers can make more than they would be paid at a full-time job.
- By paying citizen observers directly, the program aims to gather data on wildlife and incentivize conservation while spending much less than conventional conservation projects.
- The program has collected around 175,000 records in its first year of operations, but one expert notes that it has historically proven challenging to keep people engaged in long-term conservation initiatives.

George Schaller: The field biologist who helped redefine conservation
- Miriam Horn’s Homesick for a World Unknown traces the life of George B. Schaller, a field biologist whose work reshaped how animals are studied and understood.
- The book portrays a scientist defined by patience, close observation, and a disciplined effort to understand animals on their own terms, even as such an approach ran against prevailing scientific norms.
- Horn presents Schaller’s career across continents as both scientific and practical, showing how his research informed the creation of protected areas while gradually incorporating local knowledge and participation.
- Rather than probing for psychological insight, the biography mirrors its subject’s outward focus, offering a restrained account that raises broader questions about attention, conservation, and what it means to share a world with other species.

Defying conflict to track the world’s rarest chimpanzees
GASHAKA GUMTI NATIONAL PARK, Nigeria — Here in Nigeria’s largest protected wilderness area lies one of the last strongholds of the Nigeria–Cameroon chimpanzee (Pan troglodytes ellioti), the world’s rarest chimpanzee subspecies. For nearly a decade, however, this population has lived largely out of sight. Once a leading hub for field research in West Africa, Gashaka […]
The mother of orangutans
Dr Birutė Galdikas spent almost 50 years studying solitary and elusive orangutans in Borneo, at a time when no one believed it possible. Her pioneering work transformed scientific understanding of the great apes and their behavior. She passed on March 24 at the age of 79. Dr. Galdikas was one of three women who revolutionised […]
In zoos, ‘peaceful’ bonobos are just as aggressive as chimps, study suggests
A new study of our two closest living relatives finds that, at least in zoos, bonobos may not be more peaceful than chimpanzees. Bonobos (Pan paniscus) are only found south of the Congo River in the Democratic Republic of Congo, where food is abundant and evenly distributed. Chimpanzees (Pan troglodytes) range across West, Central and […]
‘Extraordinary’: Second set of rare mountain gorilla twins born in DRC’s Virunga
Virunga National Park in the Democratic Republic of Congo recorded the birth of a second set of mountain gorilla twins this year. According to park authorities, the twins were born into the Baraka family and are believed to be a male and a female, now about 2 weeks old. Their arrival follows a twin birth […]
Birutė Galdikas, primatologist who spent a lifetime studying & defending orangutans, has died at 79
- Birutė Galdikas established one of the longest-running field studies of any wild mammal, helping to transform scientific understanding of orangutans and their behavior.
- Her work combined research with hands-on rehabilitation, returning hundreds of orangutans to the wild while navigating debates over the role of intervention in field science.
- As Borneo’s forests declined, she expanded her efforts into conservation, founding an organization and working with local communities to protect habitat under growing economic pressure.
- As part of the “Trimates”, a group of female researchers recruited by Louis Leakey, she helped bring great apes into public view and frame orangutans as emblematic of broader environmental loss.

Palm oil clearing advances in Bornean orangutan habitat despite red flags
- A palm oil firm has cleared more than 3,000 hectares (7,500 acres) of forest inside a UNESCO biosphere reserve in Indonesian Borneo, threatening areas identified as orangutan habitat.
- The concession overlaps with a wildlife corridor linking two national parks, raising concerns over habitat fragmentation and increased human-orangutan conflict.
- Authorities have acknowledged the presence of the habitat inside the company’s concession, but proposed voluntary conservation measures rather than halting clearing, drawing criticism from environmental groups.
- The case highlights broader issues of weak enforcement, disputed land rights with Indigenous communities, and supply-chain loopholes that continue to allow deforestation-linked palm oil into global markets.

World Rewilding Day: Hope for species and ecosystems
World Rewilding Day on March 20 celebrates human efforts to rewild and restore degraded areas. Rewilding can focus on a single species, a city park, or even an entire island, and Mongabay has reported on such efforts from around the word. Rewilding in France’s Dauphiné Alps France’s largest rewilding project is underway in the Dauphiné […]
Facebook shuts Indonesia groups after Mongabay and Bellingcat report illegal wildlife trade
- Facebook parent company Meta has closed nine groups on the social network after reporters from Mongabay and Bellingcat found evidence of illegal wildlife trade being conducted openly on the platform in Indonesia.
- In one Facebook group, reporters last year found an advertisement for a rhinoceros hornbill (Buceros rhinoceros), a protected species.
- “Bad actors constantly evolve their tactics to avoid enforcement, which is why we partner with groups like the World Wildlife Fund and invest in tools and technology to detect and remove violating content,” Meta said in a statement.

A bonobo named Kanzi could play pretend, challenging ideas about animal imaginations
- Kanzi, a language-trained bonobo, identified and tracked pretend objects across tea party-like experiments, marking the first controlled demonstration of imagination in a nonhuman animal
- In three experiments, Kanzi repeatedly pointed to the correct location of imaginary juice and grapes, and chose real juice over pretend juice, showing that he understood the difference between real and imaginary objects.
- This study suggests that the cognitive capacity for imagination may date back 6 to 9 million years to the common ancestor of humans and great apes, though some researchers question whether simpler explanations could account for Kanzi’s responses.
- Kanzi died in March 2025 at age 44, but researchers hope to explore whether other apes, including those without extensive human language training, share this capacity.

Indonesia’s orangutan trafficking cases reveal need for a change in approach (commentary)
- Indonesia needs a new approach to illegal wildlife trafficking that does more than intercept and repatriate animals to their home habitats, a new op-ed suggests.
- Seizures of trafficked orangutans have been in the news often lately, and the nation needs to make trafficking of animals such as these unprofitable, unviable and socially unacceptable.
- “Repatriation brings (trafficking) victims home, but it should never become a routine that normalizes the crime. If a country celebrates each return while shipments keep moving through the next gap, it is responding, never preventing,” he argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

David Chivers, student of the singing apes
Field primatology expanded rapidly in the late 20th century as biologists began to study apes and monkeys where they lived rather than only in museums or laboratories. Southeast Asia’s rainforests became an important setting for that shift. Among the researchers who helped shape the discipline there was David Chivers, a British primatologist whose work […]
Cameroon’s decade of conflict leaves apes and conservationists in peril
- Dozens of protected areas in Cameroon’s anglophone regions, including parks that are home to great apes and other threatened species, have been swept up in a decade-long armed conflict between government forces and separatist militias.
- The ongoing conflict has blocked conservationists’ access to forests, and exposed conservationists, local civilians and the region’s wildlife to violence.
- Displaced people have turned to farming and hunting in forests in order to survive, while militias also hunt and camp in the forest.
- Conservationists have explored new strategies to keep their work alive, including working with local citizen scientists, but say the task of rebuilding organizations in the midst of a humanitarian crisis is huge.

Baby gorilla seized from traffickers languishes in Turkish zoo
- Türkiye has refused to return a western lowland gorilla named Zeytin, who was smuggled out of Africa a year ago; Turkish authorities seized him as an infant from the cargo hold of an airplane headed to Bangkok.
- The decision marks an about-turn in Türkiye’s plans to return him to Africa, where he’d be in a Nigerian sanctuary with other gorillas, after a DNA test ruled out Nigeria as his country of origin. Turkish authorities announced he will remain in the country permanently.
- Gorillas are social animals that live in family groups, and with no other gorillas in the country, conservationists worry Zeytin will be doomed to a life of isolation in a zoo.
- Conservationists urge Turkish officials to reconsider their decision and send the baby gorilla to a sanctuary in Africa as soon as possible so he has a better chance of possible release into the wild.

Risk-taking comes earlier in chimpanzees than in humans, study finds
- A study found that chimpanzees tend to take more physical risks as infants and young animals rather than as adolescents, like humans.
- The researchers hypothesize that the level of care humans provide may cut down on the risks young children might otherwise take.
- The team tracked how often 119 chimps dropped or leaped through the forests without holding onto any branches at Uganda’s Ngogo Chimpanzee Project, and analyzed the results according to the animals’ ages.
- Infant and young chimpanzees were more likely to launch themselves through the trees than adolescents or adults, despite the risk of injury.

Study ties same-sex behavior in primates to ecological and social pressures
- A recent study into same-sex behavior in primates finds that social organization and ecological factors, including climatic conditions, influence this behavior.
- In gorilla groups, same-sex relations can help strengthen social bonds, study lead author Chloë Coxshall told Mongabay, reducing competition and facilitating access to mates and resources.
- Gorilla groups typically consist of a dominant adult male, several adult females, and their offspring. If the dominant male has the exclusive right to mate with all females of the same group, sometimes this polygamy pushes the females to leave this family to look for other females with whom they develop intimate relationships, Malagasy primatologist Jonah Henri Ratsimbazafy said.
- Same-sex behavior doesn’t appear to have the same place in the lives of different primate species or even at various times for the same population, the study suggests. So species-specific research is needed, according to the study authors.

Indonesia revokes forest and mine permits over role in deadly Sumatra landslides
- Indonesia has revoked the permits of 28 companies after a post–Cyclone Senyar audit found environmental violations that authorities say worsened deadly floods and landslides in Sumatra in late 2025, which killed about 1,200 people.
- The revoked permits cover about 1 million hectares of forests and include major players such as pulpwood producer PT Toba Pulp Lestari, marking a shift toward framing permit enforcement as post-disaster accountability.
- Two high-profile projects in the Batang Toru ecosystem were hit: a nearly completed hydropower plant and the Martabe gold mine, both long criticized for operating in landslide-prone terrain that’s the only habitat of the critically endangered Tapanuli orangutan.
- Environmental groups have welcomed the revocations, but warn the move is incomplete, calling for transparency, ecosystem restoration, protection against permit transfers to new operators, and broader action to halt deforestation in vulnerable watersheds.

Indonesia sues 6 companies over alleged links to deadly floods & landslides
- Indonesia’s environment ministry is seeking 4.8 trillion rupiah ($284 million) in environmental damages from six companies it has linked to deadly floods and landslides triggered by Cyclone Senyar in November.
- Following the disasters, the ministry launched an investigation into dozens of companies in the region; the findings determined six companies were responsible for alleged damage to watersheds in North Sumatra.
- The areas affected include Batang Toru, an ecologically fragile ecosystem home to the Tapanuli orangutan, the world’s rarest great ape.

Twin infant mountain gorillas born in DRC
The birth of twin mountain gorillas in the Democratic Republic of Congo (DRC) is raising hopes for the survival of one of the world’s most threatened great apes. “For me, it is a huge sign of hope and a great way to start the new year,” Katie Fawcett, science director with the DRC-based Gorilla Rehabilitation […]
Chimpanzees and gorillas among most traded African primates, report finds
- A new report finds thousands of African primates, including chimpanzees and gorillas, are being traded both legally and illegally.
- Most of the legal trade in great apes is for scientific and zoo purposes, but the report raises some concerns on the legality of recent trade instances for zoos.
- Chimpanzees topped the list of the most illegally traded African primates, as the exotic pet trade drives the demand for juveniles and infants.

After Cyclone Senyar, Indonesia probes whether development amplified scale of disaster
- Cyclone Senyar triggered catastrophic floods and landslides in northern Sumatra in late 2025, but scientists and activists say decades of deforestation and landscape alteration in upland watersheds largely determined the scale of the destruction.
- The heavily hit Batang Toru landscape, home to the world’s only Tapanuli orangutan population, has become a national test case after the government ordered eight mining, energy and plantation companies to halt operations pending rare watershed-wide environmental audits.
- Investigations have raised concerns that forest clearing by a pulpwood producer, a hydropower project and a gold mine on steep terrain may have destabilized slopes and worsened runoff during extreme rainfall.
- Experts warn that once forest cover is lost in fragile tropical watersheds, disaster risks can persist for decades, making effective law enforcement — rather than weather alone — decisive for Batang Toru’s future.

Rare bats at risk as iron ore mine advances in Guinea’s Nimba Mountains
- Guinea’s government is assessing the potential impacts of a mining project in the Nimba Mountains, in a biodiversity hotspot that has been recognized as a UNESCO World Heritage Site while being threatened by mining.
- U.S. mining company Ivanhoe Atlantic recently submitted an environmental impact assessment for an iron ore mine at a site that is the only known home of two unique bat species, as well as critically endangered chimpanzees and threatened toads and frogs.
- Conservationists say open-pit mining in this ecologically sensitive region could spell extinction for Lamotte’s roundleaf bat and the orange-furred Nimba Mountain bat if their forest habitat is disturbed for mine infrastructure.

Tsunami veteran rescue elephants mobilized for Indonesia cyclone disaster relief
- The number of people killed by flash floods after Cyclone Senyar made landfall over Sumatra on Nov. 26 increased to 1,059 on Dec. 18. In Pidie Jaya district, on the north coast of the semi-autonomous region of Aceh, officials assigned a team of four rescue elephants, veterans of the recovery operation after the 2004 Boxing Day tsunami that killed more than 200,000 people in Aceh.
- The Aceh conservation agency said the elephants were uniquely able to help remove fields of logs carried down valleys by the worst flash floods to hit the region in years, with the scale of debris fields impassable to heavy machinery.
- “They are trained and experienced elephants,” the head of Aceh’s conservation agency told Mongabay, while emphasizing that officials went to great lengths to ensure the Sumatran animals’ welfare.
- At least one Sumatran elephant was presumed killed in flash floods caused by Cyclone Senyar, after residents in a village neighboring the rescue elephants’ workplace discovered the animal’s body Nov. 29.

Tapanuli orangutan, devastated by cyclone, now faces habitat loss under zoning plans
- A proposed zoning overhaul in Indonesia’s North Sumatra province could strip legal protections from nearly a third of the Batang Toru ecosystem, threatening the last remaining habitat of the critically endangered Tapanuli orangutan.
- The proposal came just before a powerful cyclone triggered floods and landslides that may have killed or displaced dozens of Tapanuli orangutans and severely damaged thousands of hectares of forest.
- The changes would weaken scrutiny of mining and plantation projects, including a planned expansion of a nearby gold mine, by removing the area’s “provincial strategic” designation.
- Conservationists say rolling back protections now would be a “nail in the coffin” for the species, calling for emergency protections and expanded conservation measures to prevent population collapse.

Orangutans rescued undergo re-training to return to the wild
NORTH SUMATRA, Indonesia — Welcome to jungle school, where orphaned orangutans are learning the basics for survival that they will need for life in the wild. At the Orangutan Information Centre (OIC) in North Sumatra, vets and biologists are rehabilitating orangutans who have been confiscated from the illegal wildlife trade. Once they have mastered the […]
Sumatran flood disaster may have wiped out a key Tapanuli orangutan population, scientists fear
- As many as 35 critically endangered Tapanuli orangutans — 4% of the species’ total population — may have been wiped out in the catastrophic floods and landslides that struck the Indonesian island of Sumatra recently, scientists warn, after the discovery of a carcass.
- Satellite and field evidence show massive destruction of the western block of the Batang Toru ecosystem, with thousands of hectares of steep forest slopes destroyed — an “extinction-level disturbance” for the world’s rarest great ape.
- Conservationists have lost contact with monitored orangutans in the disaster zone, raising fears more individuals were killed or displaced as feeding areas and valleys were obliterated.
- The tragedy has renewed calls to safeguard the Batang Toru ecosystem by halting industrial projects and granting it stronger protection, as climate-driven disasters escalate across Sumatra.

Wildlife and communities bear the cost as Simandou rail corridor advances across Guinea
- A 650-km (400-mi) railway corridor is being built that will link the iron ore mine in eastern Guinea to the country’s Atlantic port of Moribaya.
- Its route crosses forests that are home to some of the last populations of forest elephants and western chimpanzees in the country, with NGOs warning of disruptions and fragmentation of vital habitat, putting several species at risk of local extinction.
- Villagers along the route also complain that dust and pollution have impacted their livelihoods, and that compensation has been delayed or incomplete.
- Experts and civil society actors are calling for a strategic environmental study and better implementation of environmental and social management plans.

Indigenous Dayak sound alarm as palm oil firm razes orangutan habitat in Borneo
- Indigenous Dayak communities report wildlife encroaching into villages, land grabbing, and loss of cultural and livelihood resources as a palm oil company begins clearing forests on their customary lands — in some cases without consent or even prior notification.
- PT Equator Sumber Rezeki (ESR) has already cleared nearly 1,500 hectares (3,700 hectares) of rainforest inside this region that’s designated a UNESCO Biosphere Reserve and orangutan habitat, with much of the deforestation occurring this year and signaling far more destruction to come.
- The company’s parent group, First Borneo, is driving widespread deforestation across Kapuas Hulu with two other plantations, yet its palm fruit is still entering global “zero-deforestation” supply chains through intermediary mills despite corporate no-buy pledges.
- Environmental groups are urging the government to halt or revoke ESR’s permits and protect the orangutan-rich landscape, warning that continued clearing undermines Indonesia’s climate commitments and threatens both biodiversity and cultural survival.

Returning baby gibbons to the wild
Across Southeast Asia, the trafficking of gibbons is on the rise, as demand for them as pets on the black market has soared. On the frontline of this rising issue is the Sumatran Rescue Alliance which forms part of Orangutan Information Centre. But rehabilitating and releasing gibbons back to the wild can be a long […]
New population of the world’s rarest great ape discovered
A new population of the endangered Tapanuli orangutan has been discovered! Until now, we only knew of a population of around 800 individuals living in the Batang Toru forest in Indonesia’s North Sumatra province. But a new group has been found — in a peat swamp about 32 km (20 mi) away. In October last […]
Gibbon trafficking pushes rehabilitation centers to the max in North Sumatra
- Famed for their free-flow swinging through the forest canopy, gibbons are being relentlessly shot, stolen and incarcerated to supply an escalating illegal pet trade that targets babies in particular.
- Experts point to misleading social media content and a surge in private zoo collections as fueling the trade. Hundreds of the small apes have been confiscated by authorities across South and Southeast Asia in the past decade, with India and the UAE emerging as primary destinations.
- Gibbon rehabilitation centers, mostly operated by NGOs struggling for funding, are buckling under the numbers of animals in need of rescue and care.
- The trade imposes overwhelming suffering on the trafficked animals and immense wastage among the complex social groups gibbons live in, driving already threatened species ever closer to extinction.

International Gibbon Day: Spotlighting the overlooked, underprotected ‘lesser apes’
Gibbons, commonly called lesser apes, aren’t as well-known as some of their great ape cousins like chimpanzees or gorillas. But the lives of these highly arboreal primates are no less fascinating. They reside in the canopy of the tropical forests of South and Southeast Asia, living in small family groups, each patrolling its own territory, […]
Primatology goes high tech — from bioacoustics to drones & AI
- From thermal cameras to deep learning AI, researchers are reinventing how they study primates in the wild.
- What began with Jane Goodall’s observational notes has evolved into artificial intelligence that identifies chimpanzees and decodes their social lives.
- A custom-built “dronequi” with a thermal and a high-definition camera is helping scientists spot Brazil’s elusive and endangered muriquis from above the trees.
- Hidden microphones across Borneo’s rainforests capture haunting gibbon duets, revealing clues about hybridization and habitat loss.

New cluster of Tapanuli orangutans discovered in Sumatra peat swamp
- Researchers have confirmed that the critically endangered Tapanuli orangutan, previously thought to live only in Sumatra’s Batang Toru forest, also inhabits a peat swamp forest 32 kilometers (20 miles) away in the Lumut Maju village forest.
- DNA analysis of fecal samples verified the Lumut Maju apes as Tapanuli orangutans, marking the first confirmed record of the species outside Batang Toru.
- The discovery highlights the conservation value of nonprotected peat swamps, which are rapidly being cleared for oil palm plantations, threatening the orangutans’ survival.
- Conservationists warn that the isolated Lumut Maju population, likely fewer than 100 individuals, may not be viable long term unless habitat protection or relocation strategies are implemented.

Jane Goodall (1934–2025): primatologist, conservationist, and messenger of hope
- Jane Goodall, who began her career in 1960 with little formal training, transformed science’s understanding of chimpanzees and in the process reshaped the boundary between humans and animals. Her discoveries at Gombe forced the recognition of animal minds, emotions, and cultures once thought unique to humanity.
- She built on that science with activism: founding the Jane Goodall Institute in 1977, launching community-centered conservation programs across Africa, and creating sanctuaries for orphaned chimps. In 1991 she established Roots & Shoots, which grew into a vast youth movement spanning more than 100 countries.
- Beyond research and institutions, she became a global messenger, traveling up to 300 days a year to speak with audiences ranging from heads of state to schoolchildren planting trees. She insisted that empathy and objectivity could coexist and called on each person to remember that “every day you live, you make some kind of impact.”
- She described humanity as standing at the mouth of a dark tunnel with a star shining at the end—hope. To reach it, she said, required collective effort. That conviction defined her legacy: a life that reminded the world that hope is not wishful thinking but a discipline, and that every individual makes a difference.

Indonesia aims to redraw UNESCO site boundaries to allow geothermal projects
- Indonesia is proposing to redraw the boundaries of a UNESCO World Heritage rainforest, excluding two degraded areas, in order to free up geothermal potential in the region.
- Geothermal, which draws from the country’s volcanic geography, is an energy technology the government is aggressively promoting as the country moves away from fossil fuels.
- The area was declared a World Heritage Site in 2004 for its immense biodiversity: more than 10,000 plant species, 200 mammals and 580 birds, including critically endangered Sumatran orangutans, tigers, rhinos and elephants.
- The site is already on UNESCO’s World Heritage in Danger list due to deforestation, illegal logging, encroachment and road building; environmentalists warn that geothermal development risks worsening pressures on a forest ecosystem already in decline.

World Gorilla Day: What imperils our powerful cousins, and what brings hope
They’re powerful, intelligent and majestic, yet increasingly imperiled. Today, on World Gorilla Day, we recap recent Mongabay reporting that highlights both the threats facing gorillas, our great ape cousins, and some signs of hope. Emerging threats The Cross River gorilla (Gorilla gorilla diehli) continues to be one of the world’s top 25 most endangered primates, […]
In eastern Congo’s war-torn forests, Augustin Basabose gave hope to gorillas and people
- Dr. Augustin Kanyunyi Basabose, who died on August 18th, 2025, was a pioneering Congolese primatologist whose optimism and energy inspired colleagues and communities alike.
- He founded Primate Expertise (PEx), which combined science with community-led conservation, including the innovative “Ape Trees” project that restored forests while supporting livelihoods.
- Central to his work was the protection of Grauer’s gorillas, alongside training hundreds of students and urging international partners to prioritize local leadership.
- His influence is evident in eastern Congo’s forests, where gorilla populations are recovering and communities have become vital allies in conservation.

Global brands join drive for deforestation-free palm oil in Indonesia’s Aceh
- Major brands including Nestlé, PepsiCo and Unilever have launched the Aceh Sustainable Palm Oil Working Group to align with a new road map for deforestation-free palm oil in the Indonesian province.
- Aceh, on the island of Sumatra, is home to the Leuser Ecosystem and other critical habitats, but has lost nearly 42,000 hectares (104,000 acres) of forest since 2020, much of it driven by expansion of oil palm plantations.
- The initiative aims to boost the livelihoods of smallholder farmers, protect high conservation value forests, and help producers comply with new global rules like the EU Deforestation Regulation.
- While the plan has drawn international backing, civil society groups stress its success depends on ensuring accountability, transparency and sustained pressure to halt illegal deforestation.

Bonobos keep track of groupmates even when they can’t see them, study finds
Kanzi, a bonobo celebrated for his intelligence, died in March this year. A recently published study adds to his long list of cognitive abilities: he was able to track the location of people familiar to him, even when they were out of sight. He could also recognize the individual voices of his caretakers, a skill […]
World Orangutan Day: Ongoing threats & habitat loss haunt these great apes
Despite years of research into their complex behavior and intelligence, orangutans remain critically endangered on the islands of Borneo and Sumatra, where they’re endemic. Mongabay has extensively covered the threats they face from habitat degradation and what studies say about how human activities affect them. This World Orangutan Day, on Aug. 19, we take a […]
Indonesian farmers plant hope for isolated Javan gibbons
In Indonesia’s Central Java province, two groups of Javan gibbons have become isolated in two small forest patches. To help the gibbons make their way to larger forest areas, a local NGO, SwaraOwa, is working with farmers in the region to restore and build “corridors” that would connect the fragmented forest blocks, Mongabay reported in […]
Orangutans make up for lost sleep with daytime naps, study finds
- New research based on more than a decade of field observations indicates that wild Sumatran orangutans balance their sleep needs much like humans do, by napping during the day.
- The team found the shorter an individual’s sleep period overnight, the longer was its cumulative nap period the next day.
- Orangutan sleep also varied with temperature, activity levels and proximity of others, indicating the great apes have to trade off between foraging, socializing, traveling and sleep.
- Deforestation, habitat fragmentation and climate change are all likely to influence the capacity of orangutans to manage their sleep needs, with clear consequences for their overall health and survival.

World Chimpanzee Day: the strength — and fragility — of chimp memory
The more we try to understand chimpanzees, one of our closest relatives, the more we find ourselves humbled by the richness and complexity of their lives — and of their intelligence. Today, on World Chimpanzee Day, we look back at some of the latest studies that reveal facets of these great apes’ long, powerful memories. […]
Friendship benefits male and female mountain gorillas differently, study shows
- A 21-year study of 164 wild mountain gorillas found that strong social bonds produce different health effects for males and females, with males experiencing more illness but fewer injuries when they have close friendships.
- Female gorillas with strong social bonds generally had better health outcomes, experiencing 19% fewer injuries and 14% less illness compared to those with weaker social bonds.
- The benefits and costs of friendship varied based on group size, with females in small groups having fewer offspring despite better health, while those in large groups had more babies but higher rates of illness.
- The research helps explain why animals exhibit such diverse social behaviors and may inform conservation efforts for this endangered species, which numbers just over 1,000 individuals.

Signs of hope for rescued gorillas rewilded in DRC, but security concerns linger
- In October 2024, conservationists released four gorillas from the Gorilla Rehabilitation and Conservation Education Center (GRACE) in the eastern Democratic Republic of Congo back into the wild.
- The release took place in Virunga National Park — raising some concerns about their safety, as the park has been largely controlled by the armed rebel group M23 since January 2025.
- To reduce poaching in the area, GRACE says it focuses on working closely with local communities and integrating them into the organization.
- As for the released gorillas, GRACE reports that they joined a wild gorilla family and were even observed mating with the dominant male, raising hopes of a successful rewilding.

Natural bridges to reconnect the last Javan gibbons
JAVA — Indonesia. Throughout the misty mountains of central Java, the call of the Javan gibbon (Hylobates moloch) once echoed throughout the forest. Today, their voices are fading. Java is one of the most densely populated regions on Earth, and decades of logging, agriculture and infrastructure development have fragmented the forest, while rampant hunting and […]

Female bonobos wield power through unity: Study
Male bonobos are larger and stronger than females, so researchers have found it puzzling that the female apes enjoy high status in bonobo society. After analyzing three decades of behavioral data, researchers recently shared a study that pinpoints their source of power: female alliances and coalitions. “Only [among] bonobos, females form coalitions to gain power […]
Peril and persistence define the path of Africa’s conservationists
- Local conservationists across Africa face threats, isolation and underfunding, as illustrated by Nigerian conservationist Itakwu Innocent, who survived an assassination attempt and has endured years of violence and ostracism for protecting wildlife and opposing poaching in his community.
- Women and young scientists in particular face systemic barriers in conservation, including gender bias and limited access to funding and recognition, despite taking leadership roles and driving grassroots initiatives in places like Kenya, Uganda and Nigeria.
- Funding disparities and broken promises by international NGOs have undermined trust in conservation efforts, making it harder for local scientists like Owan Kenneth to gain community support without financial incentives.
- Despite these challenges, recognition and success stories are emerging, with initiatives like fellowships and community-led reforms helping figures such as Adekambi Cole, Bashiru Koroma and Asuquo Nsa Ani make tangible conservation gains and inspire others.

Fighting back against Guinea-Bissau’s illegal chimpanzee trade
- Guinea-Bissau is home to around 5% of critically endangered western chimpanzees, who face numerous threats including habitat loss, disease and illegal trade.
- A recent study found numerous chimps held in private residences and hotels, often taken from the wild as infants and held in poor conditions.
- The study’s authors recommend revising laws and penalties regulating hunting or keeping chimpanzees captive, training for officials responsible for enforcement, and a public awareness campaign about the dangers of keeping wild animals.

Silvery lining for Java’s endangered gibbon as Rahayu Oktaviani wins Whitley prize
- Indonesian conservationist Rahayu Oktaviani, known for her work with Java’s silvery gibbon, received this year’s Whitley Award for achievements in grassroots conservation.
- The 50,000 British pound ($67,000) prize will be used to expand her foundation’s work carried out local communities near Gunung Halimun-Salak National Park in West Java province.
- Halimun-Salak is where up to half of the 4,000-4,500 silvery gibbons estimated to exist in the wild remain.
- Indonesia is home to nine species of gibbon, but only one of those species lives on Java, the world’s most-populous island.

‘Satellites for Biodiversity’ upgrades with new projects and launches insight hub

Chimpanzees filmed sharing alcoholic fruits for the first time
Researchers have for the first time filmed wild chimpanzees feasting on alcoholic fruits together. It’s the “first evidence for ethanolic food sharing and feeding by wild nonhuman great apes,” they say in a new study. The research team, led by scientists at the University of Exeter, U.K., captured the footage on camera traps they set […]
Top 25 most threatened primates highlighted in new report urging action
- The latest list of the 25 most endangered primates includes nine from Asia, six from the Americas, six from the African mainland, and four from Madagascar.
- Madagascar is home to 112 known lemur species, nearly all of which face the threat of extinction or what they report calls “collective endangerment,” where entire taxonomical groups are at risk of dying out.
- Several primates feature on the list for the first time, including the Sahafary sportive lemur, red-bellied monkey, northern pygmy slow loris, Myanmar snub-nosed monkey, Central American squirrel monkey, and Bornean banded langur.
- The report is also designed to spur conservation efforts for the listed species, as happened in the case of Brazil’s pied tamarin, a species for which the Brazilian government created a strict reserve in 2024.

In Cameroon’s forgotten forests, gorillas and chimps hang on
- Many forest reserves in southern Cameroon, despite being highly degraded and fragmented, harbor significant biodiversity.
- A recent study using camera traps in two such forest reserves captured the first evidence of great apes — a gorilla and several chimpanzees — foraging in and navigating the mosaic of fragmented landscapes.
- Some of the videos show apes and humans using the same parts of the forests at different times, highlighting the risk of human-ape conflicts that could impact the already threatened great apes.
- Conservationists say the presence of great apes outside protected areas indicates the need to protect these areas, and that further research is needed to understand how great apes use fragmented landscapes close to human communities.

Poaching intensifies in M23-occupied areas of Virunga National Park
- On March 11th, 2025, Virunga National Park authorities discovered a young gorilla named Fazili caught in a poacher’s trap.
- The closure of Virunga National Park eco-guard patrol posts in areas under M23 occupation has prevented regular patrols and monitoring since April 2024, said researchers, and some locals are taking advantage of the security situation to benefit from the park’s resources, collaborate with armed groups for land, or take part in the wild meat trade.
- No species have completely disappeared from the park, and the population of gorillas continued to rise in 2024 but there has been a 50% decrease in wildlife since the M23 resurgence in 2021 and poaching is expanding, said park officials.
- About one hundred community trackers are working to protect wildlife during the security crisis.

Indigenous stewardship plays a key role in protecting imperiled primates
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. While most people are familiar with monkeys, the great apes, and possibly lemurs, fewer may realize that there are more than 500 known species of primates, making them one of the most diverse groups of mammals. These species […]
Orangutan habitat under siege as palm oil company clears forest in Borneo
- Indonesian palm oil company PT Equator Sumber Rezeki (ESR), part of First Borneo Group, has begun clearing critical orangutan habitat in West Kalimantan province, threatening high conservation value (HCV) forests and the survival of the critically endangered Bornean orangutan.
- Despite only partial clearing so far, conservationists warn that ESR plans major expansion, risking the loss of up to 10,000 hectares (about 25,000 acres) of forest, and further undermining Indonesia’s biodiversity and climate goals.
- First Borneo Group has a long record of large-scale deforestation through multiple subsidiaries, prompting major palm oil buyers like Nestlé and Musim Mas to suspend or end sourcing from the group, though some companies remain linked via supply chains.
- Environmental groups are calling for an immediate halt to ESR’s land clearing, comprehensive ecological audits, and urgent action from companies still sourcing from First Borneo Group to prevent a potential ecological disaster for orangutans and the region’s forests.

An interview with orangutan conservationist and advocate Gary Shapiro
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Orangutans, with their expressive eyes and human-like behaviors, have long fascinated us. Few people, however, have delved as deeply into their world as Gary L. Shapiro. His five-decade career began with a groundbreaking study in primate communication, where […]
Illegal trafficking of siamang gibbons is a concerning and underreported crisis (commentary)
- As authorities have continued to criminalize great ape trafficking, “small apes” like gibbons, which are also coveted by the illegal pet trade and whose trade is also lucrative, are likely to see an increasing threat to their long-term survival if nations don’t act to protect them too, a new op-ed states.
- Of all gibbon species, the siamang is the most trafficked, making it one of the most, if not the most trafficked ape species, as highlighted by a recent siamang trafficking bust at a major Indian airport.
- “Urgent action is needed to combat this ongoing crisis before the song of the siamang and other gibbons vanishes from the forests of Sumatra,” the author argues.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Bonobos combine calls in ways that resemble human language, study finds
Bonobos, one of humanity’s closest relatives, appear to string together vocal calls in ways that mirror a key feature of the human language, a new study carried out in the forests of the Democratic Republic of the Congo has found. While bonobos (Pan paniscus) produce grunts, peeps, whistles and hoots, they also combine these calls […]
Kanzi the bonobo redefined what it means to be human
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives, and story summaries. Few apes have done more to unsettle human certainties than Kanzi the bonobo. He wasn’t the first nonhuman primate to use symbols to communicate, but he was the first to do so with such fluency, subtlety and apparent […]
Mongabay investigation finds gorilla trade more widespread than previously thought
A Mongabay investigation has uncovered exclusive details about the clandestine market for gorilla and chimpanzee body parts in northeastern Nigeria, revealing that the trade works in a larger area than previously believed and kills more critically endangered gorillas than previously acknowledged. Speaking to hunters, traffickers and customers of a trade steeped in both taboo and […]
Famous bonobo Kanzi, known for smarts & gaming, dies at age 44
Kanzi, the world’s most celebrated bonobo who learned to communicate and play Minecraft with humans, died last week in Iowa, U.S., at the age of 44. Ape Initiative, a research organization in the city of Des Moines dedicated to the study and conservation of endangered bonobos (Pan paniscus) and where Kanzi lived since 2004, said […]
As apes adapt to human disturbance, their new behaviors also put them at risk: Study
- Worldwide, the most frequent causes of disturbances to ape habitats are land conversion for agriculture or logging, a recent study concludes.
- The study found that the most common ways apes adapted to habitat change included foraging for human crops, changing nesting patterns, and traveling along human-made paths.
- These changes can help apes survive in the short term, but can increase long-term risk, especially when behaviors like crop foraging bring them into conflict with humans.
- While some patterns were observed worldwide, human responses to behaviors like crop foraging varied widely, highlighting the need for local voices and priorities to be a central part of conservation planning.

Baby sightings spark hope for critically endangered gibbons in Vietnam
A community conservation team saw not one but two baby Cao-vit gibbons, one of the world’s rarest apes, in the remote forests of northern Vietnam in 2024, the NGO Fauna & Flora announced this month. The first infant sighting was in February 2024 and the second in November, in two separate troops. “It is very […]
Global outcry as petitioners demand no mining expansion in orangutan habitat
- Nearly 200,000 people have signed a petition urging U.K. multinational Jardine Matheson to halt the expansion of the Martabe gold mine in Indonesia’s Batang Toru Forest, home to the critically endangered Tapanuli orangutan.
- Agincourt Resources, a subsidiary of Jardine’s Astra International, plans to clear up to 583 hectares (1,441 acres) of forest for a new mining waste facility, which conservationists warn will push the Tapanuli orangutan closer to extinction and harm other protected species.
- Environmental groups accuse Jardines of misleading sustainability claims and the Indonesian government of failing to enforce conservation laws, despite awarding Agincourt a “green” compliance rating.
- Protesters have demanded Jardines adopt a “no deforestation, no peat, no exploitation” (NDPE) policy for its mining operations and provide clarity on conflicting deforestation figures and the compliance of its expansion plan with its approved permits.

When a chimp community lost its males, it also lost part of its love language
- A new study from Côte d’Ivoire highlights the urgent need to integrate chimpanzee cultural preservation with conservation.
- The study documents the loss of a socially learned behavior — a mating signal — among a group of chimpanzees following the poaching of all of the group’s male members.
- Once lost, behaviors that could be crucial to chimpanzee survival take years to reemerge.
- Researchers say it’s essential to preserve entire chimpanzee communities and their cultural knowledge, as well as simply protecting individuals.

The environmental toll of the M23 conflict in eastern DRC (Analysis)
- The escalating armed conflict in the Democratic Republic of Congo (DRC) has had significant — and overlooked — environmental impacts. The rate of tree cover loss in Kahuzi-Biega and Virunga National Parks has sharply increased since the conflict reignited in late 2021.
- Armed groups, both state and non-state, have profited by taxing the illegal charcoal and timber trade coming from inside these protected areas.
- Yet the impacts are complex: the broader geopolitical context also provides incentives for the M23 group to support conservation efforts in order to project themselves as providers of good governance in the region.

‘Some people will die’: Conversations with Nigeria’s gorilla hunters
- Mongabay traveled to rural villages and urban wildlife markets, gathering testimonies from hunters who have violated cultural taboos to kill apes, as well as the traffickers and traditional medicine practitioners who trade in ape parts.
- Hunting remains a key threat to the survival of gorillas and chimpanzees in Nigeria.
- In the traditions of many Nigerian clans, apes — especially gorillas — are imbued with a deep spiritual significance and recognized for their close relation to humans.
- In some cases, these beliefs contribute to the protection of apes and strong taboos against hunting or harming them; in other cases, they fuel a demand for ape parts for ritual and medicinal uses.

Guinea greenlights gold mine in habitat of critically endangered chimpanzees
The government of Guinea has issued an environmental compliance certificate to an Australian company to go ahead with its plan to mine gold within an area that’s home to critically endangered western chimpanzees. In January, Guinea’s Ministry of the Environment and Sustainable Development accepted the environmental and social impact assessment that Predictive Discovery had commissioned […]
DRC government directive triggers panic in ape sanctuaries amid ongoing conflict
- In January, the Congolese national authority in charge of the country’s protected areas issued a controversial directive asking its partner primate sanctuary to send juvenile chimpanzees to the Kinshasa zoo for a breeding program.
- Critics say the five-year program planned at the Kinshasa and Kisangani zoos, lacks the necessary infrastructure and a concrete plan, raising suspicions about the true intent of the chimpanzee transfers.
- The ongoing conflict in the country adds further uncertainty to the future of sanctuaries and the already threatened apes in the country.

Bonobos can recognize ignorance and help, a new ‘milestone’ in ape intelligence
Bonobos, one of humanity’s closest relatives, can tell when a human doesn’t know something and steps in to help — a cognitive ability never before identified in nonhuman apes, a study found. Researchers tested this in a game with three bonobos (Pan paniscus) living at Ape Initiative in Iowa, U.S. One bonobo, Kanzi, 44, is […]
Surge in legal land clearing pushes up Indonesia deforestation rate in 2024
- Indonesia’s deforestation increased in 2024 to its highest level since 2021, with forest area four times the size of Jakarta lost; 97% of this occurred within legal concessions, highlighting a shift from illegal to legal deforestation.
- More than half of the forest loss affected critical habitats for threatened species like orangutans, tigers and elephants, particularly in Borneo and Sumatra.
- Key industries driving deforestation include palm oil, pulpwood, and nickel mining, with significant deforestation in Kalimantan, Sumatra and Papua; a new pulp mill in Kalimantan in particular may be driving aggressive land clearing.
- Despite an existing moratorium on new forest-clearance permits, there’s no protection for forests within existing concessions, allowing continued deforestation, and spurring calls for stronger policies to safeguard remaining natural forests.

Chimps remember, for years, the location of ant nests that provide food
- Multiple studies have indicated that wild chimpanzees rely on memory to find ripe fruit, but less has been known about what role memory plays in sourcing foods of animal origin.
- A recent study monitored ant-feeding behaviors in savanna chimpanzees in Senegal, concluding that the apes also rely on memory to locate underground ant nests, rather than simply stumbling across nests opportunistically.
- The chimpanzees were also observed using tools and multiple senses to determine whether ant nesting sites were inhabited.

Camera traps capture first glimpse of genetically distinct chimps in southwestern Nigeria
In a win for Nigeria’s only Indigenous grassroots conservation organization, camera traps installed in Ise Conservation Area have captured the first known video of a resident Nigeria-Cameroon chimpanzee. The individual, seen swinging between tree branches and feeding on figs, is a mature male in his prime, said Rachel Ashegbofe Ikemeh, founder director of the South-West/Niger […]
To conserve chimps, understand their genetic traits and local adaptations, says study
- Chimpanzees are adapted to live across diverse habitats in Africa, but little is known about the potential adaptation of chimps in different environments.
- A new study has found that these apes possess genetic traits that help them adapt to different habitat conditions, some of which may be protecting them against malaria.
- The scientists say that, as human activities and climate change continue to threaten chimpanzees’ existence, understanding their genetics and natural history enhances knowledge of how to ensure their long-term survival and conservation.
- Given their vital ecological roles, evolutionary significance, and precarious status, chimpanzee conservation is an urgent global priority.

Increase in gibbon trafficking into India has conservationists worried
- In recent months, seizure incidents of gibbons trafficked from Southeast Asia into India have increased.
- The growing demand for gibbons as pets is behind the increased trafficking, fueled by social media and aided by porous borders and weak enforcement of wildlife laws.
- Since the trafficked gibbons are caught from the wild, the process of capture causes deaths, disturbs gibbon social structures, and causes life-long trauma for those captured alive.
- In light of increased trafficking incidents, conservationists call for stricter law enforcement, improved training to detect wildlife crimes, increased awareness, and repatriation of seized gibbons to their countries of origin.

Justice for people, animals and the environment are inextricable, Arcus Foundation says
Bryan Simmons, communications vice president at the Arcus Foundation, joins Mongabay’s podcast to discuss the 25-year-old foundation’s philosophy, human rights focus, and how the latter is linked with conservation. “ We think about humans, nonhuman animals, and the environment as one inextricable whole that has many, maybe even an unlimited number of component elements that are […]
Coming to a retailer near you: Illegal palm oil from an orangutan haven
- A surge of deforestation for oil palm plantations in a Sumatran orangutan reserve means top consumer brands may be selling products with illegal oil palm in them, a new report says.
- Rainforest Action Network (RAN) says satellite imagery shows much of the deforestation in Rawa Singkil Wildlife Reserve occurred from 2021 onward.
- That means any palm oil produced from plantations established on land cleared during that time would be banned from entering the European market under the EU’s antideforestation regulation (EUDR).
- Brands such as Procter & Gamble and palm oil traders like Musim Mas have responded to the findings by dropping as suppliers the mills alleged to be processing palm fruit from the deforested areas.

Five-month-old male gorilla, victim of illegal wildlife trade, seized in Istanbul
On Dec. 22, 2024, Turkish customs officers conducting a random search of a plane’s cargo hold found a surprise stowaway inside a small wooden crate with holes: a malnourished baby gorilla dressed in a soiled T-shirt. The Turkish Airlines flight was headed from Nigeria to Thailand and was transiting via Istanbul, authorities told local media. […]
Elephants, gorillas and chimps hold out in Cameroon’s largest protected landscape
- A new survey finds that populations of forest elephants, lowland gorillas and chimpanzees have remained relatively stable in a large landscape in southeastern Cameroon.
- In some cases, populations actually rose significantly in the region’s protected areas, but declined on the outskirts.
- Officials attribute this “positive” trend to hard work and the implementation of a “permanent presence technique” to deter poaching by engaging more closely with local communities.
- However, they say more effort is still needed to combat poaching for tusks and the trafficking of great apes.

Bonobo numbers in DRC park stable, but signs of decline appear
Bonobo populations in the Democratic Republic of Congo’s Salonga National Park remained steady between 2002 and 2018, but there are worrying signals of decline, a recent study has found. For decades, Salonga has been known to host the largest known population of bonobos (Pan paniscus), an endangered great ape found only in the DRC. However, […]
Indonesian company defies order, plants acacia in orangutan habitat
- The Indonesian company PT Mayawana Persada has shifted focus from clearing peatlands in western Borneo to planting acacia on previously cleared lands in defiance of a government order to restore damaged peatlands.
- The lands are home to the critically endangered Bornean orangutan (Pongo pygmaeus), and any habitat loss pushes the animal closer to extinction.
- Mayawana Persada’s concession spans nearly 140,000 hectares (345,900 acres), overlapping with more than 83,000 hectares (205,100 acres) of carbon-rich peatlands and more than 90,000 hectares (222,400 acres) of Bornean orangutan habitat.

Rare new Guinean flower is ‘canary in a coal mine’ — but in an actual iron mine
- Scientists have described a new species of flower that appears to only grow in a small forest patch on the slopes of a mountain range in Guinea, West Africa, where extensive open-cast mining for iron ore is set to begin soon.
- There are thought to be as few as 100 of the Gymnosiphon fonensis flowers in existence in the Boyboyba Forest, which is part of the Pic de Fon classified forest reserve in the southeast of the country.
- Mining firm Rio Tinto has pledged to protect the Boyboyba Forest and the plants and animals that live in it.
- But Boyboyba makes up only a tiny fraction within a mosaic of forests and grasslands whose ecological integrity depends on linkages extending across Simandou’s 100-kilometer (60-mile) length.

Armed conflict, not Batwa people, at heart of Grauer’s gorillas’ past decline in DRC park
- The decline in critically endangered Grauer’s gorillas between 1994 and 2003 in the highland sector of Kahuzi-Biega National Park in the Democratic Republic of Congo was due to the impacts of armed conflict, rather than the presence or absence of Indigenous communities, according to a new study.
- The finding, including recent analysis of forest loss in parts of the park where Indigenous Batwa people returned, challenges simple but competing narratives that the region’s Batwa people are either forest destroyers or forest guardians, say various primatologists.
- After the onset of the Rwandan genocide and Congo Wars, which drove an influx of refugees, poaching, hunting and mining in the region, estimates of Grauer’s gorillas dropped from about 258 to 130 individuals, only to rise again once the Second Congo War ended.
- Researchers and conservation authorities say conservation in Kahuzi-Biega National Park remains challenging, but that Indigenous people should be included in environmental stewardship.

Monitoring group cracks down on deforestation in Cameroon gorilla sanctuary
- Mengame Gorilla Sanctuary was created to protect some 26,780 hectares in southern Cameroon, and is the only large functional protected area in the region.
- In addition to critically endangered western lowland gorillas, Mengame is a refuge for an abundance of wildlife, including forest elephants (Loxodonta cyclotis) — also critically endangered — and endangered chimpanzees (Pan troglodytes).
- Logging concessions and villages surround Mengame, and satellite data show forest loss encroaching on the sanctuary and trickling into it.
- Cameroonian civil society organization Action for Sustainable Development investigated encroachment into the reserve after noticing deforestation alerts via satellite data.

Illegal gold mining drives deforestation in DRC reserve home to ‘African unicorn’
- The Okapi Wildlife Reserve in the Democratic Republic of the Congo protects vast tracks of primary Congo Basin rainforest, and is a stronghold for endangered species including the iconic okapi (Okapia johnstoni) and African forest elephant (Loxodonta cyclotis).
- The reserve is also the home to Indigenous Mbuti and Efe forest peoples, who depend on forest resources.
- Deforestation in the reserve remained high in 2023, and continued to spread this year, according to satellite data from the Global Forest Watch platform.
- Illegal artisanal and semi-industrial gold mining within the reserve is driving deforestation, poaching and environmental destruction.

A Nigerian reserve, once a stronghold for chimps, is steadily losing its forest to farming
- Oluwa Forest Reserve once protected an island of old growth forest in southwestern Nigerian.
- But satellite data show only about half of its intact forest remained at the turn of the century — and it’s only dwindled further since then.
- Poverty-driven smallholder farms and profit-driven industrial plantations are the main causes of deforestation in the reserve.
- Researchers worry that habitat loss in Oluwa is driving endangered species — such as the Nigeria-Cameroon chimpanzee — to local extinction.

Gibbons found to perform dance routines akin to ‘the robot,’ but why?
- Scientists have documented scores of animal species that perform elaborate dance displays for a variety of purposes: from courting cranes to pair-bonding penguins and waggle-dancing honeybees.
- New research and video evidence show that adult female crested gibbons also perform captivating dances in both captive and wild settings.
- The funky sequences of rump, arm and leg twitches have in the past been likened to the human “robot dance” and hypothesized as fulfilling a role in gibbon courtship.
- Experts say improved understanding of the dance brings new insight into small ape cognition and social structures, which will ultimately help conservationists better design and implement interventions to protect them.

Study finds bonobos more diverse, and more vulnerable, than previously thought
- Recently published research finds that bonobos show a much deeper degree of genetic diversity than previously thought, with the species split into three distinct subgroups that diverged tens of thousands of years ago.
- The study is based on a detailed analysis of the genomes of 30 wild-born captive bonobos, cross-referenced with more limited data from 136 wild bonobos.
- Separation into three genetically isolated groups means that each group is more vulnerable than a single unified population would be, and that loss of any of these groups would result in a significant loss of the species’ genetic diversity.

Conservationists mobilize to save Sierra Leone national park and its chimpanzees
- Sierra Leone’s Loma Mountains National Park (LMNP) encompasses the highest mountain peak in West Africa, along with valuable habitat for many threatened animals — including critically endangered western chimpanzees.
- However, satellite data show the park lost 6% of its primary forest cover between 2002 and 2023.
- Clearing in the park is being driven by farmers and ranchers who say there is not enough agricultural land in their communities and no other livelihood options; illegal marijuana cultivation is also an issue in the park.
- Conservationists, park officials, international agencies and local residents are working together to protect the park through efforts such as planting trees, training rangers, implementing educational programs in schools and promoting alternative livelihoods for surrounding communities.

Canopy bridges serve a lifeline for Sumatra’s tree-dwelling primates
- An NGO is working with local authorities in Indonesia’s North Sumatra province to build canopy bridges for primates to safely cross roads that fragment their forest habitats.
- Pakpak Bharat district has seen rapid growth of new roads to improve communities’ access to schools and hospitals, with the trade-off being that many of these roads disrupt wildlife connectivity.
- The bridges, designed to meet the needs of different species, have been used by various wildlife, though not yet the critically endangered orangutans that the designers had in mind, and are monitored regularly through camera traps and maintenance checks.
- Conservationists highlight the bridges’ role in preventing inbreeding among isolated populations and sustaining the ecosystem’s biodiversity, with hopes to expand the initiative across Sumatra.

WWF report offers glimmer of conservation hope — yet warns of a planet in peril
- WWF’s recent “Living Planet Report” offers a bit of hope, showing that mountain gorilla populations increased by 3% between 2010 and 2016.
- Conservation interventions such as dedicated management of protected areas, extensive engagement with communities surrounding parks, close monitoring of habituated gorilla groups and veterinary interventions where needed are thought to have contributed, WWF notes.
- Still, the report shows that wildlife populations across Africa have declined by 76% in the past 50 years.
- The peril of the planet is also linked to the fact that financing is inadequate, with public and private entities very often investing in activities that harm ecosystems and drive climate change.

Orangutan conservation and communication: Gary Shapiro’s half-century journey from zoos to the wilds of Borneo
- Gary Shapiro’s work on orangutan cognition and communication spans five decades, beginning with his pioneering studies teaching sign language to ex-captive orangutans in Borneo.
- His research evolved into a lifelong commitment to orangutan conservation, leading him to co-found organizations like Orangutan Foundation International, focusing on protecting orangutans and their rainforest habitats from logging and palm oil plantations.
- Shapiro advocates for “orangutan personhood,” emphasizing their intellectual and emotional capacities, and calls for global action to save both the orangutans and their critical habitats amidst the ongoing climate and biodiversity crises.
- Shapiro recently spoke with Mongabay Founder and CEO Rhett Ayers Butler about his work and the state of orangutans in the wild.

Indigenous knowledge proves key in a study of plants gorillas use to self-medicate
- Seeking plants with potential medical properties, a team of researchers in Gabon looked to the practices of two distinct groups: traditional healers living on the fringes of Gabon’s Moukalaba-Doudou National Park, and the gorillas that live inside the park, which are known to host pathogens like E. coli without developing serious illnesses.
- The researchers interviewed Indigenous Vungu healers and herbalists about their medical usage of local plants, then followed gorillas in the park to observe which plants the apes also consumed, ultimately selecting four plant species to test.
- The bark extracts tested by the team were found to have antimicrobial and antioxidant properties, as well as other bioactive compounds.
- This research, one expert says, highlights the shared evolutionary history of humans and gorillas, and the importance of preserving both apes and their habitats.

From selfies to treetops: Thai NGOs rescue and release captive gibbons
- Thailand is home to four gibbon species, all of which are listed as endangered due to habitat loss and wildlife trafficking.
- Rescue, rehabilitation and release projects play an important role in protecting gibbon welfare and restoring ecosystems, but effectively rehabilitating and releasing gibbons is both difficult and costly.
- Two organizations, the Gibbon Rehabilitation Project and Wildlife Friends Foundation Thailand, have been rehabilitating gibbons in Thailand for more than 20 years.

Chatterbox chimps converse just like humans (but with more gestures)
- Across human languages and cultures, conversing involves listening to the speaker and rapidly responding to them. This phenomenon, known as turn-taking, has so far been associated with human languages.
- A new study that analyzed conversations between five groups of chimpanzees finds that one of our closest relatives also take rapid turns in their chatter, mainly involving gestures. Chimpanzees take about 200 milliseconds between gestures before responding back and forth, just like humans.
- While researchers observed minor differences in the timing across groups, the findings suggest this is a species-wide phenomenon that can possibly be seen in all apes.
- The findings suggest that turn-taking during conversations likely evolved before languages were born.

Africa’s great ape sanctuaries are feeling the heat from climate change
- While a growing body of research highlights the impacts of climate change on wild apes, sanctuaries caring for apes are also feeling the impacts of a warming world.
- Sanctuaries across Africa are affected by changing weather patterns, including both droughts and floods, increasing the challenges of caring for resident apes.
- Extreme weather also increases the likelihood of human-wildlife conflict in conservation areas, and makes daily life more difficult for sanctuary staff and their families and communities.

Sick chimps seek out medicinal plants to heal themselves, study finds
- A new study concludes that chimpanzees displaying a range of ailments seek out plants with known medicinal properties to treat those ailments.
- The finding is important because it’s a rare instance where a species is shown to consume a plant as medicine rather than as part of its general diet.
- The study identified 13 plant species that the chimpanzees in Uganda’s Budongo Forest relied on, which can help inform conservation efforts for the great apes.
- The finding could also hold potential for the development of new drugs for human use.

Setback for Guinea mine that threatens World Heritage chimp reserve
- Liberian President Joseph Boakai is backing U.K.-Indian firm ArcelorMittal over access to a key railway in northern Liberia.
- U.S. firm HPX wants to use the rail line to ship ore from its own project in neighboring Guinea to the Liberian port at Buchanan.
- HPX’s plan to mine ore from Guinea’s Nimba Mountains has encountered fierce opposition from some environmentalists, who say it would imperil the area’s tool-using chimpanzees.
- HPX has said it will partner with South Africa’s Guma Group to build a new railway in Liberia that runs parallel to the existing one, but the plans are reportedly in jeopardy over financing.

Hold my ointment: Wild orangutan observed healing wound with medicinal plant
- Researchers observed a wild orangutan in Sumatra treating a facial wound with a plant known for its healing properties, marking the first documented case of such behavior in a wild animal.
- The adult male Sumatran orangutan was observed chewing on the plant Fibraurea tinctoria, which has pain-relieving and anti-inflammatory effects, and rubbing the resultant ointment on the wound, which later healed without infection.
- This finding supports the idea that orangutans might self-medicate, demonstrating their cognitive abilities and drawing parallels to human practices.
- Conservationists have welcomed the finding, highlighting its significance for understanding forest biodiversity and the urgency of protecting orangutan habitat amid declining populations and persistent threats.

Chimps are lifelong learners, study on tool use shows
- A recent study assessed wild chimpanzees’ use of sticks as a tool, monitoring how chimps of different ages gripped and manipulated the implement to retrieve food from tricky places.
- The study found that older chimps were more adept at choosing the right grip for the task at hand, indicating that chimpanzees, like humans, refine tool-use skills well into adulthood.
- The researchers say this continued development of skills is critical for chimpanzees’ survival in a changing climate, and that it highlights the importance of conservation interventions aimed at supporting the preservation of chimpanzee cultures.

Indonesian company defies order, still clearing peatlands in orangutan habitat
- Indonesian Pulpwood producer PT Mayawana Persada is continuing to clear peatlands on critical Bornean orangutan (Pongo pygmaeus) habitat, despite a government order to stop clearing.
- An NGO coalition analysis found that 30,296 hectares (74,900 acres) of peatland, including 15,560 hectares (38,400 acres) of protected lands, had been converted as of March; 15,643 hectares (38,700 acres) of known Bornean orangutan habitat were cleared between 2016 and 2022.
- Conservationists are calling on the Ministry of Environment and Forestry to revoke the company’s permits.

Indonesian capital project finally gets guidelines to avoid harm to biodiversity
- Beset by criticism over its environmental and social impacts, the controversial project of building Indonesia’s new capital city in the Bornean jungle has finally come out with guidelines for biodiversity management.
- The country’s president has hailed the Nusantara project as a “green forest city,” but just 16% of its total area is currently intact rainforest.
- The new biodiversity master plan outlines a four-point mitigation policy of avoiding harm, minimizing any inevitable impacts, restoring damaged landscapes, and compensating for residual impacts.
- The master plan considered input from experts, but several didn’t make it into the final document, including a call for the mitigation policy to extend to a wider area beyond the Nusantara site.

Sierra Leone cacao project boosts livelihoods and buffers biodiversity
- The Gola rainforest in West Africa, a biodiversity hotspot, is home to more than 400 species of wildlife, including endemic and threatened species, and more than 100 forest-dependent communities living just outside the protected Gola Rainforest National Park and dependent on the forest for their livelihoods.
- In the last few decades, logging, mining, poaching and expanding agriculture have driven up deforestation rates and habitat loss for rainforest-dependent species, prompting a voluntary REDD+ carbon credit program in 2015 to incentivize conservation and provide alternative livelihoods.
- One activity under the REDD+ project is shade-grown cacao plantations, which provide a wildlife refuge while generating income for cacao farmers in the region.
- Independent evaluations have found that the REDD+ program has slowed deforestation, increased household incomes, and avoided 340,000 metric tons of CO2 emissions annually — all while enjoying support from local communities.

Bonobos, the ‘hippy apes’, may not be as peaceful as once thought
- Bonobos have a reputation of being the hippies of the ape world, due to their propensity to “make love, not war.”
- But a new study reveals that bonobos, found only in the Democratic Republic of Congo, may not be as peaceful as once thought.
- Researchers discovered aggressive acts between bonobos from the same group exceeded those recorded among chimpanzees, and that aggressive male bonobos were more successful in mating.
- The study provides a more nuanced analysis of these endangered apes, but also highlights the need to protect them from hunting and habitat loss.

Jane Goodall at 90: On fame, hope, and empathy
- Jane Goodall's 90th birthday is today, April 3, 2024. To mark the occasion, Goodall sat down with Mongabay Founder and CEO Rhett Ayers Butler at his home in California.
- In the conversation, Goodall delves into the evolving consciousness regarding environmental degradation and the loss of biodiversity, while stressing the importance of fostering hope amidst the doom and gloom often associated with these issues.
- "I've come to think of humanity as being at the mouth of a very long very dark tunnel and right at the end there’s a little star shining. And that's hope," she said. "However, it’s futile to just sit and wonder when that star will come to us. We must gird our loins, roll up our sleeves, and navigate around all obstacles that lie between us and the star."
- The conversation also touches upon the transformative power of youth engagement in environmental activism. Goodall highlights the influence young people can have on older generations, emphasizing the importance of voting in elections as a means to support candidates who prioritize environmental concerns.

Report links pulpwood estate clearing Bornean orangutan habitat to RGE Group
- NGOs have accused PT Mayawana Persada, a company with a massive pulpwood concession in Indonesian Borneo, of extensive deforestation that threatens both Indigenous lands and orangutan habitat.
- In a recent report, the NGOs also highlighted links that they say tie the company to Singapore-based paper and palm oil conglomerate Royal Golden Eagle (RGE).
- RGE has denied any affiliation with Mayawana Persada, despite findings of shared key personnel, operational management connections, and supply chain links.
- The report also suggests the Mayawana Persada plantation is gearing up to supply pulpwood in time for a massive production boost by RGE, which is expanding its flagship mill in Sumatra and building a new mill in Borneo.

Smaller population estimate underscores urgency of saving Cao-vit gibbon
- A recent survey based on “vocal fingerprinting” puts the total population of Cao-vit gibbons at just 74 individuals, down from previous estimates of 120.
- Researchers say the lower number represents more precise data, not an actual decline in gibbon numbers.
- However, habitat loss and hunting, along with a slow rate of reproduction, have pushed Cao-vit gibbons to the edge of extinction.
- Reforestation and establishing protected forest corridors are key to increasing population numbers, while inbreeding remains a concern for the small population.

Palm oil deforestation persists in Indonesia’s Leuser amid new mills, plantations
- Deforestation for palm oil persists in Indonesia’s Leuser Ecosystem, including inside a national park that’s supposed to be off-limits to plantation activity, a new investigation has found.
- The Rainforest Action Network (RAN) characterizes the current deforestation trend as a “death by a thousand cuts,” with a large number of small operators hacking away at the ecosystem, in contrast to past deforestation carried out by a small number of large concession holders.
- RAN’s investigation also identified two new palm oil processing mills near the deforesting concessions, indicating that the presence of the mills, which need a constant supply of palm fruit, may be a driver of the ongoing deforestation.
- There’s a high risk that mills in the area may ultimately be supplying deforestation-linked palm oil to major global consumer products companies, including those with stated no-deforestation policies.

Norway pension fund breaks with U.K. conglomerate Jardines over endangered orangutan habitat
- Norway’s state pension fund, the world’s largest sovereign wealth fund, has cut ties with Jardine Matheson (Jardines) due to concerns that the conglomerate’s gold mining activities in Indonesia could damage the only known habitat of the world’s most threatened great ape, the Tapanuli orangutan (Pongo tapanuliensis).
- The fund joins 29 financiers that have excluded Jardines and/or its subsidiaries from financing due to climate and environmental concerns, according to data from the Financial Exclusions Tracker.
- The Tapanuli orangutan was only first described in 2017, and its estimated population numbers fewer than 800 that survive in a tiny tract of forest; 95% of the ape’s historical habitat has been lost to hunting, conflict killing and agriculture.
- The Martabe mining concession in northern Sumatra lies in the portion of the orangutan’s habitat, the Batang Toru forest, with the largest orangutan population, where the probability of the species’ long-term survival is highest; the fund worried that further expansion of the mine would increase threats to the ape.

Indonesian gold mine expanding in ‘wrong direction’ into orangutan habitat
- A gold mine in the only known habitat of the critically endangered Tapanuli orangutan is expanding, prompting alarm from activists and conservationists.
- The Martabe mine on the Indonesian island of Sumatra, run by a company associated with the U.K.’s Jardine Matheson Holdings, already cleared 100 hectares (about 250 acres) of forest from 2016 to 2020, and looks set to clear another 100 hectares.
- Advocacy group Mighty Earth says the expansion will impact an area recently established to help protect the orangutan and other threatened species.
- Jardines says an independent forestry and sustainability assessment concluded that the long-term impact of the planned exploration and development work was minimal.

No joking: Great apes can be silly and playfully tease each other, finds study
- Cracking a good joke is no laughing matter, but the complex cognitive abilities that underpin humor have so far been studied mostly in humans, with our great ape cousins going largely overlooked.
- Now, a new study reports playful teasing behavior — a precursor to joking — in small groups of chimpanzees, gorillas, bonobos and orangutans.
- The study is the first to define playful teasing as a distinct behavior separate from play in great apes and describe its various forms.
- The findings suggest that the cognitive requirements for joking and playful teasing evolved at least 13 million years ago in ancestors common to humans and great apes.

Impunity for Cambodia’s exotic pet owners as trade outpaces legislation
- High-profile interventions by Cambodia’s former leader and weak legislation have allowed the illegal wildlife trade to persist largely in the open.
- The case of a gas station menagerie in western Cambodia is emblematic of the ease with which even endangered species can be bought and sold.
- The collection, owned by a police officer, includes cockatoos from Indonesia, marmosets and parakeets from South America, and a native gibbon.
- Authorities said they were aware of the collection, but were “following the format” set in the wake of their 2023 seizure of peacocks from a breeder, which culminated in them having to return the birds after then-prime minister Hun Sen criticized their actions.

Male dominance isn’t the default in primate societies, new study shows
- A recent study challenges the notion that it’s a man’s world when it comes to primate social groups.
- The study found that while a majority of species (58%) exhibited male-biased power structures, female- or co-dominant structures were identified in every major primate group.
- The pattern held true for apes as well; all five gibbon species studied were classified as non-male-dominant, as were bonobos among the great apes.
- Experts say that long-held beliefs in male power as the default among primates could have developed due to chance (the earliest studied primate species happen to have male-dominant structures), or due to “who’s been doing the research and publishing.”

Skywalker gibbons confirmed in Myanmar for the first time
- Skywalker hoolock gibbons have been confirmed for the first time in the forests of northeastern Myanmar, with researchers using acoustic monitoring and DNA analysis to identify 44 groups of the imperiled primates.
- The discovery officially extends the range of the endangered species, first described as recently as 2017, beyond the borders of China; the population found in Myanmar is the largest known population of the species on the planet.
- The researchers also conducted a threat analysis, identifying habitat loss from logging and mining and hunting for the illegal wildlife trade as major pressures.
- Given the prevailing political conflict and paucity of well-managed protected areas in Myanmar, local communities and experts recommend scaling up grassroots and Indigenous-led conservation efforts to protect the threatened primates and their forest home.

Bees bring honey and hope to a forest reserve in Nigeria
- Nigeria’s Ngel Nyaki Forest Reserve boasts more plant species than any other montane forest in Nigeria.
- The reserve is also home to a small population of endangered Nigeria-Cameroon chimpanzees.
- However, human pressures have resulted in deforestation of portions of Ngel Nyaki.
- An initiative hopes to safeguard and rehabilitate Ngel Nyaki’s habitat by training community members in beekeeping.

Great apes can remember long-lost friends and relatives
Great apes, such as bonobos (Pan paniscus) and chimpanzees (Pan troglodytes), exhibit remarkably enduring social memories. In one notable experiment, a bonobo was able to recognize her sister after being apart for 26 years, setting a record for the “longest-lasting nonhuman social memory” observed in scientific research. Researchers employed eye-tracking cameras to monitor the apes’ […]
Bid to mitigate gold mine’s impact on orangutans hit by stonewalling, data secrecy
- An international conservation task force says a gold mine operator in Indonesia resisted its efforts to carry out an independent review of the project’s impact on Tapanuli orangutans, the world’s most threatened great ape species.
- The ARRC Task Force, which had been engaged by the Martabe gold mine in early 2022 to advise on minimizing its impacts on the critically endangered species, said the task force was expected to carry out a mere “tick box exercise.”
- U.K. conglomerate Jardine Matheson Holdings Ltd., which ultimately owns the mine, said the reason the engagement fell through was Indonesian legal restrictions on data sharing, which meant the ARRC couldn’t access the government-held data it needed.
- Part of the Martabe concession overlaps onto the Batang Toru Forest, the only home of the Tapanuli orangutan; advocacy group Mighty Earth says most of the deforestation detected recently in the concession occurred in orangutan habitat and carbon-rich landscapes.

Freeing trees of their liana load can boost carbon sequestration in tropical forests
- Lianas are woody, vining plants, many of which thrive in areas where forest has been disturbed — often to the detriment of the trees they use to climb towards the sun.
- New research shows that liana cutting is a low-cost natural climate solution that can boost the amount of carbon absorbed by a tree.
- The study’s results indicate that freeing just five trees per hectare of their liana load could remove 800 million tons of C02 from the atmosphere over a 30 year period if applied across 250 million hectares of managed forest.
- Liana cutting is also seen as a way for foresters and conservationists to work together, improving both the forest’s power to sequester carbon and the quality of the timber that is being logged, as well as a way to generate income for local communities.

Western hoolock gibbon conservation in Bangladesh urgently needs funding (commentary)
- Western hoolock gibbons play an important role in seed dispersal for forest regeneration in northeastern India, western Myanmar, and eastern Bangladesh.
- But the species is among the world’s most threatened primates, and faces a host of threats in Bangladesh ranging from deforestation for agriculture to the illegal wildlife trade.
- These animals “urgently require a comprehensive program that not only focuses on habitat conservation but also on scientifically sound translocations of isolated groups and individuals….Without significant financial support, the survival of Bangladesh’s gibbons remains in jeopardy,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.

A rush for ‘green’ iron is on in Guinea. Will chimpanzees be a casualty?
- In December, Anglo-Australian mining giant Rio Tinto announced plans to sink $6.2 billion into a long-delayed iron ore mine in Guinea’s Simandou mountain range.
- Simandou contains the largest undeveloped high-grade iron deposits on earth, certain to be in high demand due to their suitability for low-emissions steel production.
- In the nearby Nimba mountains, another major iron deposit is moving closer to production, as a World Bank-backed project run by a subsidiary of HPX moves forward with feasibility studies.
- Both the Simandou and Nimba mountain ranges are home to critically endangered western chimpanzees, and conservationists say that mining operations there could pose a major threat to them.

Bonobos and chimps recall friends and family even after years apart: Study
- An experiment with bonobos and chimpanzees suggests the great apes remember their friends and family even after years apart.
- Louise, a bonobo who participated in the study, recognized a sister she had last seen 26 years ago, in what is now evidence of the “longest-lasting nonhuman social memory” on the scientific record.
- Laura Simone Lewis and her colleagues designed an experiment to track eye movement (used as an indicator of recognition) when the animals were faced with two photos side by side — one of a former group mate and the other of a stranger from their species.
- The team found that the kind of relationship shared by two individuals also influences recognition; if they had a more positive relationship as group mates, the bonobo or chimp directed more attention to that individual.

Newly described tree species from Sumatra could be vital for threatened orangutans
- A new species of stone oak has been described from the forests of northern Sumatra, the first of its kind found on the island in more than 10 years.
- The two lone trees are located in the remote Batang Toru forest, the only known habitat of the critically endangered Tapanuli orangutan, which was itself only described in 2017.
- The new stone oak’s acorns seem to be an important part of the orangutans’ diet, but ongoing habitat destruction means this tree is also likely to be critically endangered.
- Urgent conservation action is needed to save the remaining Batang Toru forest and establish cultivated populations of the rare oak to prevent its extinction, researchers say.

Incentivizing conservation shows success against wildlife hunting in Cameroon
- Providing farming support to communities living near a wildlife reserve in Cameroon has been shown to lower rates of hunting, according to a three-year study.
- Thirty-five of the 64 hunters enrolled in the study near Dja Faunal Reserve were able to increase their income from fishing or cacao farming, the two main economic activities aside from hunting in the region.
- The participants spent more time working on their farms and less in the forest hunting with guns, an important indicator that they weren’t targeting “animals of conservation importance and primates in particular.”
- While the results of the experiment are promising, experts say it’s not a silver bullet and should be used alongside other solutions, including education, governance, and sustainable natural resource management.

Poverty and plantations: Nigerian reserve struggles against the odds
- Located in southern Nigeria, Oluwa Forest Reserve is supposed to be a bastion for the region’s wildlife – which includes critically endangered Nigeria-Cameroon chimpanzees.
- But the influx of thousands of settlers into the reserve is coming at the cost of its rainforests, with satellite data and imagery showing ongoing clearing into primary forest.
- Palm oil companies are also establishing industrial plantations in the reserve.
- Conservationists and officials warn that vulnerable wildlife populations may be wiped out if forest loss and bushmeat hunting continues at its current rate.

Killings of Bornean orangutans could lead to their extinction
- Human actions have led to the deaths of more than 100,000 Bornean orangutans since 1999, mainly for crop protection, bushmeat or the illegal wildlife trade.
- For the first time in 15 years, researchers surveyed residents of Kalimantan, the Indonesian section of Borneo, to find out why people kill the great apes and whether conservation projects help protect them.
- Researchers found that killings seriously threaten orangutan numbers, and that conservation projects have not yet helped.

Are flame retardants about to burn a hole in biodiversity? (commentary)
- Researchers recently mapped more than 150 species of wild animals across every continent contaminated with flame retardant chemicals.
- These chemicals are added to furniture, electronics and vehicles but routinely escape such products and are found in the blood of wildlife species such as baboons, chimpanzees, and red colobus monkeys with unknown effects, but in humans these exposures are associated with lower IQs, reduced fertility, and an elevated risk of cancer.
- “Even though we lack data on flame retardants in wildlife from most tropical areas with high levels of biodiversity, the findings from Uganda strongly suggest that wildlife in other tropical ecosystems are probably affected as well,” a new op-ed states in arguing for a rapid reduction in their use.
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.

Burn now, pay later: Fines trickle in from Indonesia’s crackdown on forest fires
- Ten years since a landmark lawsuit over forest fires, the palm oil company at the center of the case has finally begun paying its $23 million fine in installments.
- The case against PT Kallista Alam (KA) was supposed to set an example for how the government is cracking down on companies that allow burning in their concessions, but has instead highlighted the difficulty of collecting on the fines.
- KA has paid just $3.6 million of its total fine, and despite a 2021 regulation barring fine payments in installments, the company has been allowed to stagger its payments over time.
- The company is one of 22 sued by the government since 2013 for fires; 14 of these have been found liable and ordered to pay a combined 5.6 trillion rupiah ($353 million), but only one has paid in full.

Myanmar’s primates and their guardians need more support, study says
- Myanmar is home to 20 species of primates, making it the seventh most primate-rich country in Asia. However, a new study shows that all species are suffering population declines, with 90% of them threatened with extinction.
- The conflict-torn country’s researchers and conservationists are working in challenging conditions and are in dire need of more support from the international community, the study says.
- Despite the bleak outlook, experts say the wealth of in-country expertise, young primatologists and local communities engaged in conservation action for primates in Myanmar is cause for hope.
- The study authors encourage conservation funders to not view Myanmar as a “no-go” zone due to the political situation, and propose recommendations to strengthen the field of primatology within the country.

Gorilla permit fraud dents community-led conservation efforts in Uganda
- Foreign tourists pay $600-$700 per person for gorilla-tracking permits issued by the Uganda Wildlife Authority, which allow them to track and spend an hour with human-habituated mountain gorilla families.
- A recent audit at the UWA showed that some corrupt officials were issuing fake permits, diverting revenue away from the agency and impacting its conservation work, including project funding for communities at the frontline of gorilla conservation.
- In response, the agency suspended 14 staff members suspected of fraud, initiated a thorough probe, and rolled out a new system for issuing permits and collecting revenue.
- Communities living near the gorilla parks, many of whom have faced restrictions on traditional rights to the forests as a result of their protected status, say they’re aware of the scandal and that it’s only the latest in their litany of grievances against the UWA.

Young firefighter killed battling inferno in Borneo orangutan habitat
- Said Jaka Pahlawan, an oil palm plantation foreman, was killed on Sept. 30 while fighting a fire in Indonesia’s Tanjung Puting National Park, a key orangutan habitat.
- The 23-year-old worked for PT Kumai Sentosa, a plantation company that had been fined in 2019 by an Indonesian court over wildfires on its concession.
- The fire this time around was in the national park, where Jaka and other employees went to tackle the blaze as government firefighters responded to fires elsewhere.
- Friends of the young firefighter told Mongabay that Jaka was a dedicated professional who had participated in conservation activities in the area.

Deforestation surges in hotspot of critically endangered Bornean orangutans
- Deforestation within a pulpwood concession that overlaps with key orangutan habitat in Indonesian Borneo has escalated in recent months.
- Concession holder PT Mayawana Persada cleared 14,000 hectares (34,600 acres) of forest between January and August, or 40 times the size of New York’s Central Park, of which 13,000 hectares (32,100 acres) were areas identified as orangutan habitat.
- In July alone, the company cleared 4,970 hectares (12,300 acres), the highest monthly deforestation figure recorded.

Deforestation for palm oil continues in Indonesia’s ‘orangutan capital’
- Carbon-rich peatlands continue to be cleared and drained in an Indonesian protected wildlife reserve known as the “orangutan capital of the world,” with 26 kilometers (16 miles) of new canals dug so far in 2023, up from 9 km (5.6 mi) in 2022, according to an investigation by the advocacy group Rainforest Action Network (RAN).
- While new plantations appeared to have not been established yet along the new canal channels, there is a mosaic of illegal oil palm around the locations of the new canal, indicating a future development of palm oil.
- As new canals continue to be dug, deforestation has also picked up, reaching 372 hectares (919 acres) in the first six months of 2023, a 57% increase from the same period in 2022.
- RAN has called on global brands like Procter & Gamble, Nestlé, PepsiCo and Unilever to address the development of new canals and illegal plantations as their supply chains are tainted with illegal palm oil from the wildlife reserve.

Study: Wild meat trade from Africa into Belgium a health and conservation risk
- Up to 4 metric tons of wild meat is illegally entering Europe through Brussels’ international airport alone every month, a new study says.
- The source for much of this meat is West and Central Africa, with some of the seized meat found to be from threatened or protected species such as tree pangolins and dwarf crocodiles.
- The study comes more than a decade after the same group of researchers found an estimated 5 metric tons of bushmeat entering via Charles de Gaulle airport in Paris weekly, suggesting enforcement since then hasn’t been effective.
- Experts are calling for better detection of wild meat trafficking and stricter enforcement of penalties against the trade in protected species, as well as more frequent checks of the legal trade to uncover illegal shipments.

Elephants invade as habitat loss soars in Nigerian forest reserve
- Elephants straying out of Afi River Forest Reserve in the Nigerian state of Cross River are reportedly damaging surrounding farms.
- This uptick in human-wildlife conflict comes as satellite data show continuing and increasing deforestation in the Afi River reserve and other protected areas.
- The habitat in Afi River Forest Reserve provides a crucial corridor that connects critically endangered Cross River gorilla populations in adjacent protected areas.
- As in other Nigerian forest reserves, agriculture, poverty and a lack of monitoring and enforcement resources are driving deforestation in the Afi River reserve.

World’s top sovereign fund latest to cut ties with dam in orangutan habitat
- The Norwegian state pension fund has recommended excluding a major Chinese hydropower developer from further investment, due to its association with a dam in Indonesia that threatens the world’s rarest great ape.
- The dam is being built by a subsidiary of Chinese state-owned multinational Power Construction Corporation of China Ltd. (PowerChina) in the only known habitat of the critically endangered Tapanuli orangutan, a species with a total population of less than 800.
- The Norwegian pension fund’s ethics council launched an investigation into the project and concluded that it will “have a destructive and permanent impact on the environment, which will pose a serious threat to the survival of this orangutan species as well as other critically endangered species.”
- Environmentalists say Norway’s recommendation further reinforces the risks the dam project poses on the orangutan and should prompt the project’s main backers, the Chinese and Indonesian governments, to abandon the project.

Migrating orangutan males imitate locals to learn about food: Study
- Male orangutans that resettle to a new area appear to be imitating the behavior of a local individual in an effort to survive and find a future home range, a new study says.
- The researchers have dubbed the behavior learning skill as “peering” and describe it as when migrant male orangutans intensively observe over a period of time a certain local they have chosen as a role model.
- The scientists analyzed data of hundreds of Sumatran and Bornean orangutans in research stations in Aceh and Central Kalimantan.
- Indonesia is home to the world’s three orangutan species: Sumatran, Tapanuli (P. tapanuliensis) and Bornean orangutans.

Drones improve counts of rare Cao-vit gibbon, identify conservation priorities
- A survey using drones has come up with a more accurate, albeit smaller, population estimate for the critically endangered Cao-vit gibbon in the border region between Vietnam and China.
- Researchers emphasize the lower estimate isn’t the result of a population decline, citing the discovery of new gibbon groups.
- The finding, they say, “feeds into our assessments of how viable the population is [and] helps us decide what conservation actions are the most urgent.”
- The survey is the latest to underscore the “limitless” utility of drones and their growing importance in wildlife surveys and wildlife research in general.

Poverty-fueled deforestation of Nigerian reserve slashes hope for rare chimps
- Less than 20 year ago, Akure-Ofosu Forest Reserve was regarded as a potential conservation site for endangered Nigeria-Cameroon chimpanzees.
- But between 2001 and 2022, the reserve lost nearly half of its old growth forest cover, a trend that shows no sign of stopping.
- Akure-Ofosu’s forest is being lost due to the proliferation small-scale farms within the reserve.
- Facing an unemployment rate surpassing 50% and a soaring level of poverty, many Nigerians have few options other than to settle in the country’s protected areas and hew farms from forest.

Orangutan ‘beatboxing’ offers clues about human language, study says
- Researchers have discovered that orangutans possess vocal abilities similar to beatboxing, where they can produce two different sounds simultaneously.
- The study suggests that these vocal abilities in orangutans may have existed in ancient, extinct relatives of humans and could have influenced the development of human speech.
- The vocal control and coordination abilities of wild great apes, including orangutans, have been underestimated compared to the focus on vocal abilities in birds.
- Further research is needed to understand how orangutans develop their beatboxing-like calls and to explore the connections between bird vocalizations, great ape vocalizations, and human speech.

Big potential and immense challenges for great ape conservation in the Congo Basin, experts say
- Great apes are on track to lose 94% of their range to climate change by 2050 if humans do nothing to address the problem, according to research.
- In the great apes stronghold of the Congo Basin, national interests in natural resource exploitation, a lack of security in areas like the Albertine Rift, hunting, and the illegal wildlife trade all greatly impact populations of bonobos and mountain gorillas.
- In this episode of Mongabay Explores, Gladys Kalema-Zikusoka, Kirsty Graham, Terese Hart, and Sally Coxe speak with Mongabay about the threats to bonobos and mountain gorillas, the lessons learned from decades of conservation efforts, the importance of great apes for the protection of Congo Basin rainforest, and ways forward for conservation as well as livelihoods for Indigenous and local communities.

Why did the orangutan cross the toll road to Indonesia’s new capital city?
- The sighting of a Bornean orangutan crossing the sight of an under-construction toll road to Indonesia’s new capital city has renewed questions about the government’s claims about how “green” the $32 billion project really is.
- It’s not the first wildlife sighting in the construction area; there have already been five instances of clouded leopards seen in the area.
- Activists say these sightings indicate that the development of the new capital and its supporting infrastructure is being carried out without proper planning and thus will threaten the region’s ecosystem and wildlife.
- The toll road project has cleared hundreds of hectares of forests that serve as a buffer zone to a protected forest area that’s a habitat for threatened species such as orangutans, sun bears, proboscis monkeys and Irrawaddy dolphins.

Survival and economics complicate the DRC’s bushmeat and wild animal trade
- Hunting for bushmeat can impact the populations of rare and threatened wildlife in forests around the world.
- In the Democratic Republic of Congo, subsistence hunting is often intertwined with the trade of bushmeat and in some cases live animals to sate the demand from larger markets, which can increase the pressure on wildlife populations.
- The trade of bushmeat provides one of the few sources of income for hunters, porters and traders, as well as a source of protein for families, in the town of Lodja, which sits close to forests that are home to unique species.
- Activists in Lodja and the DRC are working to save live animals from entering the illicit trade of endangered species and encourage alternative sources of income to the commercial trade of wild meat and animals.

Ground-nesting chimps hold lessons for conservation — and for human evolution
- Eastern chimpanzees in the northern Democratic Republic of Congo frequently build nests and sleep overnight on the ground even in areas where predators are present, a recent study finds.
- The ability of these relatively small-bodied apes to sleep on the ground without fire or fortifications suggests that other hominids, including early humans, could have moved from the safety of trees earlier than thought.
- The study also found that chimpanzees were not deterred from ground nesting when they shared space with humans — as long as those humans were not hunting.
- This, the researchers say, suggests chimpanzee conservation and human use of forests can coexist.

Camera trap images of rare gorillas with infants bring hope in DRC
- Camera traps in the Tayna Nature Reserve in the Democratic Republic of Congo have recorded two mother-infant pairs of eastern lowland gorillas, confirming the presence of healthy family groups in one of their last strongholds.
- This subspecies is critically endangered, with only 6,800 individuals left in the world, and is threatened by hunting, deforestation and mining activities
- Gorilla Rehabilitation and Conservation Education (GRACE) operates the world’s only sanctuary for rescued eastern lowland gorillas, and employs local communities in a key role in monitoring efforts in Tayna.

Fight for survival: The battle to save the last Tapanuli orangutans
North Sumatra, Indonesia — In 2017, the Tapanuli orangutan was identified as a new species of great ape — and immediately became the most endangered great ape on the planet, with a total population of less than 800. The orangutans are restricted to a small area of the Batang Toru ecosystem in Indonesia’s North Sumatra […]
World’s newest great ape faces habitat loss, multiple threats: Will it survive?
- Scientists designated the Tapanuli orangutan (Pongo tapanuliensis) as a new species in 2017, and it was immediately noted as being the rarest and most threatened great ape with fewer than 800 individuals in western Indonesia.
- The IUCN estimated the apes’ population fell by 83% in recent decades, and the species continues to face grave threats due to habitat loss, a gold mine, a hydroelectric plant and the expansion of croplands.
- While some conservation efforts offer hope, researchers say a coordinated plan is needed to ensure the species survives.

Saving the last Tapanuli orangutans
- The Tapanuli orangutan was described in 2017 as a new great ape species, and with a population of less than 800, is the most endangered great ape on the planet.
- Its habitat has been drastically reduced by deforestation driven by mining, agriculture and logging.
- A Chinese-backed hydropower dam project, under construction since 2015, is cutting across the forests where the orangutans live, increasing their risk of extinction.
- People living in surrounding areas have opposed the dam project over fears of losing their homes and livelihoods, but have faced attempts to silence their resistance.

Guinea’s crab-fishing chimps are in good health, study shows, but threats loom
- An international team has used genetic censusing — analyzing DNA from fecal samples — to work out the size of a population of critically endangered chimpanzees in Guinea.
- At least 136 adult chimpanzees were identified living in four communities on the western flanks of Guinea’s Nimba Mountains, part of a UNESCO World Heritage Site.
- Iron ore mining is planned in a northern section of the mountains, in an area the chimpanzees use to disperse between their separate communities.
- The scientists warn that human activities that hinder or restrict chimpanzee movements or territories can trigger deadly battles between rival communities of the apes and compromise their genetic diversity.

To save Hainan gibbons, Earth’s rarest primate, experts roll out the big tech
- As scientists and the Chinese government ramp up efforts to protect the critically endangered Hainan gibbon, technology is playing an important part in helping track and monitor the species better.
- In recent years, bioacoustics, infrared technology and machine learning are among the tools that have been used to make data collection and analysis easier in the study of Hainan gibbons.
- According to estimates, there are only 35 or 36 individuals of the species left, limited to Bawangling National Nature Reserve in China’s Hainan province.

Palm oil deforestation hits record high in Sumatra’s ‘orangutan capital’
- Deforestation in a protected wildlife reserve known as the “orangutan capital of the world” hit a record high in 2022, according to various analyses.
- The forest loss was driven by clearing for oil palm plantations by well-connected local elites, rather than smallholders, according to advocacy group Rainforest Action Network (RAN).
- RAN’s investigation found that palm oil from these illegal plantations had wound up in the global supply chains of major brands like Procter & Gamble, Nestlé, PepsiCo and Unilever, among others.

DRC’s endangered bonobos face another threat to their survival: malaria
- Along with humans, great apes like gorillas and chimpanzees are known to get infected with malaria, but evidence about the parasite’s effects on bonobos has been scant.
- A recent study that analyzed the feces of bonobo across the species’ range found that one bonobo population showed evidence of both malaria infection and a genetic variation that would likely protect them against severe disease.
- This genetic variation was less common in other populations, suggesting that other bonobo groups could be in trouble if climate change brings malaria-carrying mosquitoes into their habitats.

Orangutan death in Sumatra points to human-wildlife conflict, illegal trade
- The case of an orangutan that died shortly after its capture by farmers in northern Sumatra has highlighted the persistent problem of human-wildlife conflict and possibly even the illegal wildlife trade in Indonesia.
- The coffee farmers who caught the adult male orangutan on Jan. 20 denied ever hitting it, but a post-mortem showed a backbone fracture, internal bleeding, and other indications of blunt force trauma.
- Watchdogs say it’s possible illegal wildlife traders may have tried to take the orangutan from the farmers, with such traders known to frequent farms during harvest season in search of the apes that are drawn there for food.
- Conservationists say the case is a setback in their efforts to raise awareness about the need to protect critically endangered orangutans.

In Sumatra, increased orangutan sightings point to growing threats to the apes
- Villagers in the Batang Toru forest in northern Sumatra say orangutan sightings in their farms and settlements have increased recently.
- They attribute this to the animals being driven out of their forest habitat by ongoing construction of a hydropower plant and dam.
- The construction activity puts added pressure on the already critically endangered Tapanuli orangutan, which numbers fewer than 800 individuals scattered in populations that could be cut off from each other by the project.
- Villagers say it’s important to preserve the animals, as they’re a key seed disperser for the fruit trees that farmers here depend on.

Trafficking and habitat loss spell doom for Bangladesh’s western hoolock gibbons
- The western hoolock gibbon is a globally endangered species but in Bangladesh is considered critically endangered, due to continued habitat depletion, hunting and trafficking.
- According to a 2021 study, the country’s hoolock gibbon population dropped by around 84% over the past four decades, with the total estimated population now at just 469 individuals.
- Wildlife experts say the apes are hunted for food locally, and trafficked across the border to India and China for the illegal pet trade and for use in traditional medicine.
- They’ve called for an urgent conservation initiative to protect the gibbons and their habitats, including greater involvement by border guards and intelligence agents to crack down on trafficking.

Chimpanzee nut cracking leaves telltale marks on stones, providing clues to human evolution
- Groups of chimpanzees in West Africa use stone tools in distinctly different ways to crack open nuts.
- Researchers used 3D scans to trace wear patterns on the tools, called “hammerstones” and “anvils.”
- The different tool uses may help archaeologists identify signs of early stone tool technology in human ancestors more than 3 million years ago.

Fears for academic freedom as Indonesia doubles down on scientists’ ban
- Indonesian academics continue to question the government’s justification for banning five foreign scientists who called out the official narrative that the country’s orangutan populations are increasing.
- The initial ban made nebulous accusations that the scientists had “negative intentions” that could “discredit” the government, but the environment ministry now claims they broke the law — without specifying how.
- Indonesian scientists campaigning for academic freedom say the government’s move is a form of anti-science policy and power control over the production of knowledge.
- The environment ministry has refused to engage with either the foreign scientists or the academic freedom caucus, with researchers saying this is part of a larger trend of independent science being constrained.

What can Half or Whole Earth conservation strategies do for orangutans?
- In a recent study, a team of researchers attempted to predict how the application of two global conservation ideas, Half-Earth and Whole Earth, would impact orangutan conservation on the island of Borneo in Southeast Asia.
- Numbers of all three species of orangutans continue to drop due to habitat loss and killing by humans, despite an estimated $1 billion spent on conservation efforts in the past two decades.
- The researchers surveyed orangutan experts about their thoughts on the application of the two ideas on Borneo; the resulting analysis predicts continued declines for Bornean orangutans under both Half-Earth and Whole Earth paradigms, though they report that the species would fare better under Half-Earth.
- Proponents of the Whole Earth paradigm argue that the authors of the study misinterpreted some of the idea’s central tenets, however.

Indonesia’s orangutans declining amid ‘lax’ and ‘laissez-faire’ law enforcement
- The widespread failure by Indonesian law enforcers to crack down on crimes against orangutans is what’s allowing them to be killed at persistently high rates, a new study suggests.
- It characterizes as “remarkably lax” and “laissez-faire” the law enforcement approach when applied to crimes against orangutans as compared to the country’s other iconic wildlife species, such as tigers.
- Killing was the most prevalent crime against orangutans, the study found when analyzing 2,229 reports from 2007-2019, followed by capture, possession or sale of infants, harm or capture of wild adult orangutans due to conflicts, and attempted poaching not resulting in death.
- The study authors call for stronger deterrence and law enforcement rather than relying heavily on rescue, release and translocation strategies that don’t solve the core crisis of net loss of wild orangutans.

Mountain gorilla reproduction slows with female transfers, study shows
- Successful conservation interventions have helped mountain gorilla populations recover from 620 in 1989 to more than 1,000 today.
- However, mountain gorilla habitat is not expanding, and a growing body of research indicates that increasing density comes with a price: More groups sharing territory leads to more frequent intergroup violence.
- A new study finds that when intergroup contact increases, so do transfers of females between groups, leading to delayed reproduction.
- The study also emphasizes that multiple factors, such as delayed reproduction and increased mortality, cascade to create a slowdown in population growth.

Tunnel collapse at dam project in orangutan habitat claims yet another life
- A tunnel collapse, the second this year, at the site of a planned hydroelectric dam in Sumatra has killed another Chinese construction worker.
- The latest incident brings the death toll at the project site to 17 in the space of less than two years.
- The police have declared the death to be accidental, but the string of incidents has raised concerns over the safety of the project, which is already controversial because it threatens to fragment the only known habitat of the critically endangered Tapanuli orangutan.

Severe malaria cases in rescued orangutans raises concerns for wild populations
- Researchers in West Kalimantan, Indonesia, sampled orangutans and found a high prevalence of malaria.
- In some cases, malaria resulted in severe illness among the great apes, causing concern about the conservation implications for the animals.
- On the plus side, all of the orangutans inflicted with severe illness responded well to treatment and recovered.
- Some experts says these findings underline the need for a precautionary principle when translocating or reintroducing orangutans that test positive for malaria.

Study highlights ‘friends with benefits’ relation between gorillas and chimps
- A new long-term study points to lasting social relationships between chimpanzees and gorillas in the wild.
- The study showed that individuals from both species actively seek out each other in a variety of contexts.
- The benefits of these interactions go beyond protection from predators, and include learning social skills and finding fruiting trees.
- But these social interactions also provide the potential for transmission of deadly diseases like Ebola, which pose as big a threat to the long-term survival of gorillas and chimps as hunting and habitat destruction.

Easygoing bonobos accepting of outsiders, study says
- Bonobos are well known for their peaceable relations within family groups, but there’s less scientific consensus about how much tolerance they extend to individuals outside of their core groups.
- A recent study set out to examine this question by observing members of habituated bonobo communities in the Democratic Republic of Congo, and comparing their behavior to observations of chimpanzee groups in Uganda’s Kibale National Park.
- The researchers found that, compared to chimpanzees, bonobos maintain strong and distinct core groups, but also exhibit frequent and peaceable between-group interactions.
- The findings give conservationists a better understanding of bonobo social behavior, which in turn can inform conservation actions.

Thai zoos come under scrutiny again as tourism rebounds from COVID-19
- The welfare of rare and often threatened species in Thailand’s tourism and pet trades has long been a concern for animal rights activists.
- The conditions in which many of the animals are kept became even direr during the COVID-19 pandemic, when border shutdowns meant no visitor revenue to care for the animals.
- NGOs are working to rescue and rehabilitate some of the animals from zoos and private owners, but acknowledge that few, if any, of the animals can ever be released back into the wild.
- They add that rescue and rehabilitation is only part of the solution, and that more focus should go on protecting the natural environment and habitats of these animals over the long term.

As Indonesia paints rosy picture for orangutans, scientists ask: Where’s the data?
- Foreign scientists who were apparently banned for questioning the Indonesian government’s claim that orangutans are widely increasing in number insist none of the available data support the claim.
- Erik Meijaard, Julie Sherman, Serge Wich, Marc Ancrenaz and Hjalmar Kühl were blocked from carrying out conservation-related research in the country after writing an op-ed that the forestry ministry deemed had “negative indications” that could “discredit” the government.
- “If the government says that populations are growing I assume they have data that none of us have access to,” Meijaard told Mongabay. The ministry didn’t respond to requests for comment.
- The banning of the five is the latest in a string of actions by the current government that local and foreign academics have slammed as “repressing science.”

Trafficked: Kidnapped chimps, jailed rhino horn traffickers, and seized donkey parts
- Armed intruders who kidnapped three young chimpanzees from a sanctuary in the DRC have threatened to kill them unless a ransom is paid for the apes’ return.
- Calls for renewed focus on organized crime in wildlife trafficking, as specialized courts in Uganda and the DRC are delivering convictions for wildlife crimes that in the past would likely have gone unpunished.
- A seizure in Nigeria has sounded the latest alarm over growing exports of donkey parts for traditional Chinese medicine.
- Trafficked is Mongabay’s bi-weekly bulletin rounding up brief stories from the illegal wildlife trade in Africa.

With less than 10 years to save Sumatran elephants, what’s being done?
- The provinces of North Sumatra and Aceh in Indonesia’s embattled and highly deforested island of Sumatra are some of the last holdouts for the critically endangered Sumatran elephant.
- With the clock running out to save them, and extractive industries like oil palm fragmenting their habitat, pushing them to the brink, villagers are taking measures into their own hands by reducing human-elephant conflict to save the species from further harm.
- Also in North Sumatra lies a controversial planned hydroelectric dam site in the last habitat of the critically endangered Tapanuli orangutan, a project that has also claimed 16 human lives in less than two years.
- On the Mongabay Newscast this week, Leif Cocks, founder of the International Elephant Project and the Orangutan Project, weighs in on the status of the Sumatran elephant and the Tapanuli orangutan.

‘Cursed’ dam project in orangutan habitat claims 16th life in less than 2 years
- A tunnel collapse at the site of a planned hydroelectric dam in Sumatra has killed a Chinese construction worker, bringing the death toll at the project site to 16 in the space of less than two years.
- The project is already hugely controversial because it sits in the only known habitat of the Tapanuli orangutan, a critically endangered species that scientists warn will be pushed further toward extinction if their habitat is fragmented by the dam.
- Opponents of the Chinese-backed project have long argued that the site’s topography and location near a fault line make it “wholly unsuitable” for a large-scale infrastructure project, and that the developers should abandon it.

Snares: Low-tech, low-profile killers of rare wildlife the world over
- Snares are simple, low-tech, noose-like traps that can be made from cheap and easily accessible materials such as wire, rope or brake cables. Easy to set, a single person can place thousands, with one report warning that snares “are a terrestrial equivalent to the drift nets that have devastated marine and freshwater biodiversity.”
- Used throughout the tropics, one estimate says 12 million snares are present in protected areas of Cambodia, Laos and Vietnam, with the number likely far greater across the wider Southeast Asian region. Snaring is also common in Africa.
- While many hunters target smaller game to eat or sell, snares are indiscriminate, and often maim or kill non-targeted animals such as elephants, lions and giraffes, and endangered species including gorillas, banteng, dhole and saola. One report calls snares “the greatest threat to the long-term presence of tigers in Southeast Asia.”
- Snaring is difficult to stop. Hunters hide snares from their prey, which makes them hard to spot, though rangers are known to collect thousands. It’s “like a game of hide and seek,” says one expert. “Forest rangers hasten to dismantle snare lines even as poachers reconstruct them at other locations.” Behavior change is one solution.

Study highlights elusive Cameroonian gorillas, and the threats encircling them
- Ebo Forest in southwestern Cameroon hosts a rare and enigmatic population of western gorillas.
- A new study analyzes how gorillas use the forest, finding they primarily inhabit just 2,200 hectares (5,400 acres) within the 200,000-hectare (490,00 acre) forested area, and seem to spend much of their time in small patches of grassland rather than forest.
- Experts say they hope the findings will help guide conservation efforts for the critically endangered species.
- While not directly targeted for hunting, the gorillas face a multitude of threats, including gathering of forest products, a road construction project, and the secondary effects of other species in their habitat being hunted for bushmeat.

Deforestation intensifies in northern Malaysia’s most important water catchment
- The Ulu Muda rainforest is one of the last large, continuous tracts of forest in the Malay Peninsula, providing vital habitat for countless species as well as water for millions of people in northern Malaysia.
- Satellite data indicate deforestation activities are intensifying in the greater Ulu Muda landscape, including in protected areas such as Ulu Muda Forest Reserve.
- Sources say the forest loss is likely due to legal logging.
- Conservationists worry that the loss of Ulu Muda rainforest will have detrimental impacts on the region’s biodiversity and water security, as well as contribute to global climate change.

Chimps digging wells shows learned behavior that may help amid climate change
- A recent study using camera traps and direct observation documented well-digging behavior in a group of chimpanzees in Uganda, initiated by a female that had immigrated into the group.
- Researchers were surprised to observe this behavior in this rainforest-dwelling population as water tends to be easily accessible in this habitat.
- The findings suggest this learned behavior may be helpful for the conservation of this group, as the chimps have picked up an adaptive measure that could help them survive a drought.

Deforestation in Borneo threatens one in four orangutans, study says
- Deforestation in Borneo will destroy the habitat of more than 26,000 orangutans, a quarter of the population of the critically endangered species, by 2032, a new study says.
- Researchers used historical data and modeling with known drivers of deforestation to project that orangutan habitat a tenth the size of Italy could be lost over the next decade.
- Forests at highest risk of deforestation include those near areas that have already experienced forest loss, as well as industrial timber and oil palm plantation concessions.
- The study suggests the largest immediate conservation gains could come from curbing deforestation in and around plantation landscapes, through efforts such as zero-deforestation pledges, sustainability certification, ecosystem restoration, and a halt on clearing land.

Plantations threaten Indonesia’s orangutans, but they’re not oil palm
- A significant portion of orangutan habitat in Indonesia lies within corporate concessions, but industrial tree companies, like pulp and paper, don’t have strong enough safeguards and commitment to protect the critically endangered apes, a new report says.
- According to the report by Aidenvironment, there are 6.22 million hectares (15.37 million acres) of orangutan habitat within corporate oil palm, logging, and industrial tree concessions.
- Of the three types of concessions, industrial tree companies are the “key stakeholder” as they operate with much less transparency and scrutiny than the palm oil sector, Aidenvironment says.

Inside Sierra Leone’s Tacugama Chimpanzee Sanctuary
- The Tacugama Chimpanzee Sanctuary, located on the outskirts of Freetown, is a refuge for orphaned chimpanzees in Sierra Leone.
- Part of a network of sanctuaries in West Africa, Tacugama provides a home for orphaned western chimpanzees, which are critically endangered.
- Mongabay’s Ashoka Mukpo visited Tacugama in April and sat down with Bala Amarasekaran, the sanctuary’s founder.

Data from droppings: Researchers draw up a genetic ID map for chimps
- As part of a broader project studying the cultural and genetic diversity of chimpanzees across Africa, researchers have used fecal samples from 48 sites across the continent to create a genetic identity data set of chimpanzees across the species’ range.
- The data set supports the division of chimpanzees into the four currently recognized subspecies, as well as shedding light on historic gene flow between subspecies and between chimpanzees and bonobos.
- The data set can help conservationists determine the genetic origin of chimpanzees confiscated from the illegal wildlife trade and identify poaching hotspots, researchers say.

Wildlife don’t recognize borders, nor does climate change. Conservation should keep up
- A set of studies focused on the China-Vietnam border demonstrates that the impacts of climate change will make transboundary conservation even more important for endangered species like the Cao-Vit gibbon and tiger geckos.
- Conservation in transboundary areas is already challenging because of physical barriers, like fences and walls, as well as non-physical ones, such as different legal systems or conservation approaches between countries on either side.
- Changes in climatic factors such as temperature and rainfall are likely to mean that, for many species, suitable habitat may be in a different place than it is now — and in many cases, this could be in a different country

Côte d’Ivoire’s chimp habitats are shrinking, but there’s hope in their numbers
- Despite a decade of uncontrolled poaching, researchers have found what they describe as a “healthy” population of 200 chimpanzees in Côte d’Ivoire’s Comoé National Park.
- With the help of camera-trap footage, researchers found that the Comoé chimps display unique types of behaviors not found in other chimp populations in West Africa.
- Like elsewhere in West Africa, the chimps’ habitat remains under pressure from farming and herding.

Road projects threaten integrity of Uganda’s mountain gorilla stronghold
- Ugandan authorities are considering two road projects through Bwindi Impenetrable National Park, home to half of the world’s population of endangered mountain gorillas.
- The proposed new road will impact connectivity between Bwindi and Sarambwe Nature Reserve in the neighboring Democratic Republic of Congo, says the International Gorilla Conservation Programme.
- Most conservationists don’t dispute the need for improved road infrastructure for nearby communities, but say they’re concerned the government is overlooking less harmful alternatives.

Protecting the last Cross-River gorillas | Chasing Deforestation
Cross River State, Nigeria — Chasing Deforestation is a series that explores Earth’s most threatened forests through satellite data and reporters on the ground. In the first episode, your host, Romi Castagnino, takes you to the forests of Cross River State in Nigeria. We do a deep dive into the history and social dynamics that […]
Bonobos torn from the wild make their return, with a helping hand
- An NGO in the Democratic Republic of Congo has returned 14 bonobos into the wild — only the second time ever a bonobo group has been reintroduced to their natural habitat.
- Friends of Bonobos runs a bonobo sanctuary in the DRC where bonobos orphaned by illegal poaching are tended to and rehabilitated.
- The nonprofit released the first group of bonobos in the Ekolo ya Bonobo Community Reserve in 2009, and after more than a decade of preparation and several delays, the second batch was safely moved into the reserve in March.
- The Ekolo ya Bonobo Community Reserve was officially designated a protected area in 2019, and Friends of Bonobos plans to seek National Park status for the forest. This effort could help ensure the two groups remain safe in the wild.

How many orangutans does $1 billion save? Depends how you spend it, study finds
- A recent study evaluating spending on orangutan conservation, calculated to amount to more than $1 billion over the past 20 years, found wide variations in the cost-effectiveness of various conservation activities.
- The study found habitat protection to be by far the most effective measure, followed by patrolling.
- By contrast, habitat restoration; orangutan rescue, rehabilitation, and translocation; and public outreach were found to be less cost-effective.
- The study relied on building a model that correctly accommodated numerous factors, something both the researchers and outside experts highlight as a challenge.

Saving Nigeria’s gorillas was also meant to help communities. It hasn’t (analysis).
- In this analysis, Mongabay contributor Orji Sunday reflects on conversations with people living in and around Nigeria’s Cross River National Park, established in 1991 to protect Cross River gorillas and other threatened species.
- For many people in the area, conservation, whether under British colonial rule or since independence, has been experienced as a loss of autonomy and livelihood, and as a string of broken promises of prosperity.
- With few alternatives and a growing population, people describe becoming ever more dependent on forests and wildlife to survive, regardless of their personal feelings about conservation and apes.
- Well-designed and monitored alternative livelihood initiatives show some chances of success, but scaling them up, and consistently monitoring them, remain challenging.

Deforestation on the rise as poverty soars in Nigeria
- Akure-Ofosu Forest Reserve was established to help protect what is now one of largest remaining tracts of rainforest in Nigeria, and is home to many species.
- But fire and logging is rampant in the reserve, with satellite data showing it lost 44% of its primary forest cover in just two decades; preliminary data indicate deforestation may be increasing further in 2022.
- Sources say poverty is the driving force behind the deforestation of Akure-Ofosu and other protected areas in Nigeria.
- According to the World Bank, 4 in 10 Nigerians – about 80 million people – were living below in poverty in 2019, with the COVID-19 pandemic pushing another 5 million people below the poverty line by 2022.

Civil conflict in Cameroon puts endangered chimpanzees in the crosshairs
- Declared a national park in 2009, Mount Cameroon hosts an array of biodiversity, including endangered Nigeria-Cameroon chimpanzees.
- Efforts to protect the area have been complicated by an armed conflict, the Anglophone crisis, that has displaced hundreds of thousands of people and pushed both refugees and armed combatants into the area’s forests.
- The conflict compounds existing conservation challenges including population pressure, land clearing and conversion, demand for bushmeat, and weak law enforcement.

In Nigeria, a decade of payoffs boosted global wildlife trafficking hub
- An investigation by Nigeria’s Premium Times and Mongabay has found evidence of systematic failure by Nigerian law enforcement and the judicial system to hold wildlife poachers and traffickers accountable.
- Our analysis of official wildlife crimes data, supported by numerous interviews with prosecutors, environmental campaigners and traders at wildlife markets in Lagos, Cross River, Abuja, Ogun and Bauchi states, found a near-total reliance on minor out-of-court settlements in trafficking cases.
- Despite numerous high-profile, multimillion-dollar trafficking busts at Nigeria’s ports since 2010, no one has faced jail terms as a result.
- The reliance on informal payments to local officials encourages corruption, experts say, while sporadic crackdowns on wildlife markets have not stopped traders operating in the country’s commercial capital.

Refuge of endangered ‘African unicorn’ threatened by mining, poaching, deforestation
- Okapi Wildlife Reserve in the Democratic Republic of the Congo (DRC) shelters some 470 mammal and bird species, including up to 20% of the world’s remaining endangered okapi (Okapia johnstoni), which are related to giraffes.
- While Okapi Wildlife Reserve has escaped much of the environmental destruction affecting surrounding areas, satellite data show deforestation has been increasing in the reserve in recent years.
- Satellite imagery shows the expansion of what appear to be gold mines in the latter half of 2021.
- Conservationists say illegal mining is attracting more people to the reserve, which in turn increases poaching and deforestation.

Call for COVID rules that reduced infections in gorilla parks to remain
- Respiratory infections recorded among mountain gorillas in Rwanda’s Volcanoes National Park dropped from a pre-pandemic average of 5.4 outbreaks among family groups to just 1.6 per year since the start of the COVID-19 pandemic in March 2020.
- Conservation group Gorilla Doctors, whose Rwanda team recorded the decrease in infections, says the decline correlates with lower visitor numbers to the park as well as masking requirements and an increase in the distance tourists must stay from habituated apes.
- In a recent letter in the journal Nature, Gorilla Doctors and the park’s chief warden called for these stricter measures to be kept in place permanently.

The chimp doctor will see you now: Medicating apes boost the case for conservation
- Researchers in Gabon’s Loango National Park observed chimps applying insects to their own wounds, as well as the wounds of other individuals.
- Researchers identified 76 instances of this behavior being repeated on 22 different chimps.
- Experts say these findings could help guide conservation efforts for not just these endangered great apes, but also their entire ecosystem.

Malaysia’s white-handed gibbons may be two subspecies, not one, study shows
- Scientists sequencing the genes of white-handed gibbons of the Malaysian subspecies (Hylobates lar lar) have discovered unusual mutations that hint at the existence of a separately evolving population in the peninsula.
- This particular population is so genetically different, it could potentially qualify as a new and distinct subspecies, the researchers said.
- For scientists looking to translocate and reintroduce captive gibbons into the forest, knowing the finer details like which subspecies and population a particular animal originated from can help reduce interbreeding and ensure the gibbons stay healthy in the long run.
- For researchers looking to differentiate between gibbons of the same subspecies, focusing on a particular segment of mitochondrial DNA can be a powerful method for pinpointing the population an animal originated from.

Greater Mekong primates struggle to cling on amid persistent threats: Report
- The Greater Mekong region is home to 44 species of non-human primates, including gibbons, lorises, langurs, macaques and snub-nosed monkeys, several of which were first described within the last few years.
- Habitat loss and hunting driven by the wildlife trade and consumption have driven many of the region’s primates to the brink of extinction, with many species now only existing as tiny populations in isolated, fragmented pockets of habitat.
- Experts say controlling the illegal wildlife trade is complicated by the presence of legal markets for primates, often for use in biomedical research.
- Despite the challenges, conservation action at local levels is achieving results for some primate species in the region while also enhancing livelihoods and ecosystem services for local communities.

Endangered chimps ‘on the brink’ as Nigerian reserve is razed for agriculture, timber
- As rainforest throughout much of the country has disappeared, Nigeria’s Oluwa Forest Reserve has been a sanctuary for many species, including Nigeria-Cameroon chimpanzees – the rarest chimpanzee subspecies.
- But Oluwa itself has come under increasing deforestation pressure in recent years, losing 14% of its remaining primary forest between 2002 and 2020.
- Oluwa’s deforestation rate appears to be increasing, with several large areas of forest loss occurring in 2021– including in one of the last portions of the reserve known to harbor chimps.
- Agriculture and timber extraction are the main drivers of deforestation in Oluwa; smallholders looking to eke out an existence continue to move into the reserve and illegally clear forest and hunt animals for bushmeat, while plantation companies are staking claims to government-granted concessions.

Deadly raids are latest case of abuse against Indigenous Batwa in DRC park, groups say
- The number of attacks by security forces on Indigenous Batwa villages in the Democratic Republic of Congo’s Kahuzi-Biega National Park has tripled in the past four weeks, according to the Forest Peoples Programme (FPP).
- DRC soldiers and park rangers are accused of burning several Batwa villages to the ground, killing one man and possibly a pregnant woman, and injuring at least two other women during raids that continued until mid-December.
- Indigenous rights groups have demanded a formal investigation into the reports, and called on park funders to pay attention to alleged crimes committed using their money.
- Park officials have denied that there are any Batwa communities officially living inside the park, and say the target of the raids is an armed man that carried out a deadly attack in the city of Bukavu.

Lockdown underscores Uganda’s overreliance on tourism to fund conservation
- When the COVID-19 pandemic broke out in March 2020, Uganda quickly shut down parks like Bwindi Impenetrable National Park to protect the gorillas and chimpanzees from getting infected.
- Tourism provides up to 60% of the Uganda Wildlife Authority’s operating revenue and is also an important source of income for communities living around Bwindi.
- Poaching in Bwindi rose sharply during lockdown in 2020 as some villagers entered the park to hunt for food or an income.
- One NGO reinforced its programs supporting public health and livelihoods in an attempt to reduce this pressure.

Uganda’s ‘Dr. Gladys’ honored by U.N. for work linking conservation and health
- The United Nations on Dec. 7 recognized Gladys Kalema-Zikusoka as one of its “champions of the Earth” for promoting the One Health approach to conservation in Africa.
- The Ugandan conservationist, a trained wildlife veterinarian, established the NGO Conservation Through Public Health (CTPH) in 2003 to ensure better health care access for communities living around Bwindi Impenetrable National Park and to lower the risk of human pathogens jumping to mountain gorillas.
- UNEP selected Kalema-Zikusoka for its science and innovation category; the other awardees were Barbados Prime Minister Mia Mottley, Kyrgyz youth activist Maria Kolesnikova, and the nonprofit Sea Women of Melanesia.
- “If you make the community feel that you care about them, then there’s less need to fight them,” Kalema-Zikusoka said.

U.K. conglomerate Jardines ‘caught red-handed’ clearing orangutan habitat in Sumatra
- A U.K. conglomerate’s Indonesian subsidiary is deforesting the only known habitat of the critically endangered Tapanuli orangutan, despite promising to stop doing so, satellite imagery indicates.
- Since April this year, PT Agincourt Resources has cleared 13 hectares (32 acres) of rainforest in Sumatra for its Martabe gold mine, on top of the 100 hectares (247 acres) deforested since 2016.
- Agincourt is a subsidiary of Astra International, Indonesia’s biggest conglomerate, which in turn is a subsidiary of London-listed Jardine Matheson; the latter in 2019 agreed not to expand farther into Tapanuli orangutan habitat following a campaign by the NGO Mighty Earth.
- But the latest satellite imagery shows it has been “caught red-handed,” said Mighty Earth, which also noted that customers of Astra International’s palm oil subsidiary, including Unilever and Hershey’s, were also calling for a group-wide no-deforestation commitment.

Extinction not only threatens primates—their parasites are in danger, too
- Primates threatened with extinction have highly specific parasites that will likely vanish if their hosts go extinct.
- Parasites play essential roles in ecosystems, but most are so understudied that scientists don’t understand the consequences of losing them.
- If in peril due to a diminishing number of hosts, parasites may try to jump to new host species—potentially triggering unforeseen infections.

For world’s rarest gorillas, camera traps prove pivotal for protection
- Cross River gorillas are Africa’s rarest and most endangered ape, once thought to have already been driven to extinction.
- Camera traps have emerged as a critical tool for monitoring the health and population sizes of the subspecies.
- Recent images have shown multiple young gorillas, which conservationists take as a sign that protection measures are working, and which have also helped raise awareness and funding for Cross River gorilla conservation.

Report: Orangutans and their habitat in Indonesia need full protection now
- A new report underscores the urgency of protecting Indonesia’s orangutans and conserving their remaining habitat, warning that Asia’s only great ape is in crisis.
- The report from the Environmental Investigation Agency says the Indonesian government has systematically failed to protect orangutan habitat, enforce existing wildlife laws, or reverse the decline of the three orangutan species.
- “For decades, Indonesia has prioritized industry and profit over environmental health and biodiversity protection, and orangutans have paid the price,” said EIA policy analyst Taylor Tench.
- The report calls for protecting all orangutan habitat (much of which occurs in oil palm and logging concessions), halting a dam project in the only habitat of the Tapanuli orangutan, and recognizing Indigenous claims to forests adjacent to orangutan habitat.
