A ‘lost’ Philippine pigeon reappears after 20 years — but its forest is disappearing
- Philippine conservation nonprofit CCIPH and Indigenous Iraya Mangyan forest patrollers documented a Mindoro bleeding-heart pigeon, providing the first confirmed image of the critically endangered species in two decades.
- Two independent ornithologists confirmed the identification based on the bird’s orange-red breast marking, iridescent green plumage, and other distinctive features.
- The image was recorded at an elevation above 900 meters (about 3,000 feet), higher than the species’ typical lowland range of 400-88 m (1,300-2,600 ft).
- Experts called for expanded camera-trap surveys, a comprehensive population. assessment, stronger habitat protection, and measures to address logging, poaching and accidental trapping.

Hidden cameras reveal macaws’ secret lives
High up in the Amazon canopy, camera traps have recorded the entire breeding cycle of red-and-green macaws in Peru’s Madre de Dios region. Researchers watched these birds team up to defend their nest, raise a chick, and face rivals — all from a single artificial nest box. As natural nesting spaces are lost to logging, […]
Koala on the road? AI signs could alert drivers in real time
- A new AI-powered camera system is being experimented in the Australian state of Queensland to identify koalas crossing the road in the dark.
- The cameras could be incorporated into smart road signs to warn drivers about koalas crossing up ahead.
- Vehicle strikes are a huge contributor to koala mortality; koalas are often forced to cross roads to move across habitats that have been left fragmented by deforestation and urbanization.

Counting bats in the dark
How do you count and keep track of bats? Advances in videography, including thermal cameras, have made it easier to spot bats. But these animals move fast, travel in big groups and are often found in the dark — making analysis of the data a tough task. Scientists have developed a new software called Thrutracker […]
Penguins are breeding much earlier in a warming Antarctic, study finds
- Penguins on the Antarctic peninsula and surrounding islands are breeding substantially earlier in the year than just a decade ago, according to new research.
- The study used remote cameras to track the breeding season of three penguin species across 37 colonies from 2012 to 2022.
- Gentoo penguins advanced their breeding season by about 13 days over the 10-year period, while Adélie and chinstrap penguins each shifted breeding by about 10 days.
- Researchers don’t yet know how the changes are impacting penguins, but it could lead to a mismatch in food availability for chicks or create competition among species for food and other resources.

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.

Indigenous myths reveal Amazon’s past truths: Interview with Stéphen Rostain
- Recent archaeological findings, bolstered by laser-based lidar mapping and by archaeologist Stéphen Rostain, reveal that the Amazon supported vast and complex ancient urban societies.
- In an interview with Mongabay, Rostain says the ancient Upano Valley culture in Ecuador collapsed due to severe drought, offering a stark warning for the Amazon’s current climate vulnerability.
- Rostain says he’s hopeful that a new archaeological understanding of the Amazon will challenge centuries of prejudice against Indigenous people and offer answers for the future.

Deep-sea shark recorded on video for first time using low-cost camera
Most of what’s known about the deep-sea painted swellshark, was learned when researchers found specimens in the fish markets of Bali and Lombok, Indonesia back in the early 2000s. However, a recent survey in Timor-Leste used low-cost deep-sea cameras to observe the painted swellshark in the wild for the first time. Researchers recorded footage of […]
Survey uncovers ‘wildlife treasure’ in Cambodian park — but also signs of threats
- A survey of a little-known patch of forest on Cambodia’s border with Thailand has uncovered a “treasure of wildlife,” including potentially new-to-science plant species.
- The Samlout Multiple Use Area was established 30 years ago to conserve natural resources while also developing economic activities, but deforestation rates in the region have matched the national average.
- The survey, conducted by Fauna & Flora and commissioned by the Maddox Jolie-Pitt Foundation, found about 140 bird, 30 mammal, 15 bat and 50 orchid species.
- But camera traps used in the survey also recorded the presence of armed humans in the area and evidence of snare traps, prompting calls for improved protection by law enforcement agencies.

Satellites and lidar get AI boost to count forest carbon stock worldwide
- A newly launched tool combines satellite images, lidar data and artificial intelligence to estimate carbon stored in forests around the world.
- The Forest Carbon Monitoring tool, developed by Earth-imaging company Planet, trained an AI model using the organization’s archival satellite data and globally available lidar data.
- The model is now being used in conservation efforts as well as in the voluntary carbon market.

Camera trap survey in Cambodia’s Cardamom Mountains finds 108 species
What’s new: The first ever camera trap study from Cambodia’s Central Cardamom Mountains has captured footage of 108 wildlife species, including 23 that are threatened with extinction. This survey confirms the area’s importance as a biodiversity hotspot, a recent report says. What the study says: The Central Cardamom Mountain Landscape (CCML), part of the Indo-Burma […]
New brown bear ‘stronghold’ in Nepal redraws species’ range map
- A population of brown bears has been discovered in western Nepal, extending the species’ known geographical range and suggesting a potential “contact zone” between the Himalayan and Tibetan brown bear subspecies.
- Researchers from the Himalayan Wolves Project discovered the bears during camera-trap studies in the Limi Valley, which is rich in biodiversity but has seen limited ecological research compared to other regions of Nepal.
- The bears exhibit physical traits associated with the Tibetan subspecies, but genetic analysis is necessary to confirm their subspecies classification and determine if they’re hybrids.
- Research indicates that habitat for brown bears in Nepal may shrink significantly due to climate change, with predictions showing up to 82% habitat loss by 2070 if global temperatures rise by 2.7°C (4.9°F) by end-century, emphasizing the urgent need for conservation efforts.

Collar cameras shed light on quirky baboon diet
- A new study has found that chacma baboons (Papio ursinus) like to feed on antelope poop, especially during drier months when vegetation might be sparse.
- Researchers deployed collar cameras attached to four baboons in South Africa as part of a documentary film in 2017; they later analyzed footage from two of them.
- They also gained insights into how baboons were interacting with other species that share their habitat.
- According to the study, collar cameras gave researchers a “primate-eye perspective” into the animals’ lives, and could be used in the future to gain more insights into other behavioral traits.

‘We’re doing so much with so little’: Interview with WildLabs’ Talia Speaker
- The use of technology for conservation and wildlife monitoring increased in recent years, with camera traps and remote sensing being the most popular tools, a report has found.
- The report by conservation technology network WildLabs also found that artificial intelligence was highly ranked for its potential impact, but was ranked low in terms of current performance because of accessibility issues.
- Marginalized groups, including women and people from lower-income countries, were found to face disproportionate barriers to accessing resources and training.
- “The motivation behind this research was to capture the experiences of the global conservation technology community, and to speak with a united voice,” says Talia Speaker, who led the research.

In Laos, forest loss and carbon emissions escalate as agriculture intensifies
- Shifting cultivation is expanding into intact forest frontiers in Laos, triggering a spike in associated carbon emissions, according to a new study based on satellite data.
- As the dominant land use type in Laos, shifting cultivation has affected roughly one-third of the country’s total land area over the past three decades, the study says.
- The study also highlights how fallow land, a vital carbon store in Laos, is increasingly undermined by farming practices characterized by shorter fallow periods.
- The authors say their data can be used by policymakers to design programs that support more sustainable forms of shifting cultivation. Experts urge that such interventions sensitively consider why remote communities might be forced to transition away from traditional, subsistence-based farming toward intensified systems.

No animals harmed as wildlife specimen collection goes digital in 3D
- Conservationist and photographer Scott Trageser has developed a 3D scanning system that could potentially reshape how animals are studied in the wild.
- The system uses an array of cameras that work in sync to rapidly capture photos of animals in the wild, yielding a virtual 3D specimen viewable on smartphone or with a VR/AR headset.
- The noninvasive methodology will enable scientists to conduct research without euthanizing animals; digital specimens also have the advantage of not degrading over time.
- However, the high cost and technical skills required to assemble and operate the system, in addition to its inability to gather internal morphological data, are hurdles to its widespread use.

Betting on biodiversity: Q&A with Superorganism’s Kevin Webb & Tom Quigley
- Superorganism is a newly launched venture capital firm, touted to be the first that’s dedicated to addressing the biodiversity crisis.
- The firm aims to support startups that are developing and deploying technology to prevent biodiversity loss and protect nature.
- The firm’s early portfolio includes companies that are working to tackle extinction drivers and finding solutions that lay at the intersection of biodiversity conservation and climate change mitigation.

Can digital twins help save the Amazon? (commentary)
- Spread across highland forests, tropical steppes, and low-lying floodplains — all of which are affected by varying degrees of human influence — the Amazon is a complex ecosystem. Yet, it remains inadequately mapped.
- Considering the degree of threat facing the Amazon and its global importance, it is critical to develop better methods for monitoring and comprehending this ecosystem.
- Carlo Ratti, the director of MIT’s Senseable City Lab, and Robert Muggah, the co-founder of the Igarapé Institute, argue that creating a “digital twin” of the Amazonian ecosystem could potentially serve as a means to aid its preservation while fostering a regional bioeconomy.
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.

Origami-inspired sensor platforms tumble like leaves to study forests
- Scientists have developed a tiny, lightweight, shape-shifting platform that can hold a variety of environmental sensors and be dropped from drones to study far-flung locations.
- The design for the platforms, known as microfliers, was inspired by origami, the Japanese art of paper folding.
- Each microflier can snap between two shapes while in the air, allowing them to have different trajectories and thus disperse across a larger area when they land.
- Though they haven’t been used in any scientific studies yet, microfliers could be useful for the large-scale deployment of environmental sensors measuring and transmitting data on pressure, temperature, humidity, or lighting conditions, among others.

Taking the global pulse of biodiversity monitoring: Q&A with Andrew Gonzalez
- A group of scientists have put forward a proposal to set up a global network that centralizes biodiversity monitoring and facilitates seamless sharing of data.
- The group wants its proposed Global Biodiversity Observing System (GBiOS) to function similarly to the network of local weather monitoring stations across the world, whose data are used to analyze and monitor climate change.
- While the technology being used to monitor biodiversity has become more sophisticated over the years, there still exists a void in getting different communities to work together to address the broader challenges in dealing with the biodiversity crisis.
- “We would not only federate people who are working together more effectively, but also fill many of the gaps in the data that currently exist in the biodiversity field,” Andrew Gonzalez, who is leading the proposal for GBiOS, told Mongabay.

New Tree Tech: Real-time, long-term, high-tech reforestation monitoring
- This four-part Mongabay mini-series examines the latest technological solutions to help tree-planting projects achieve scale and long-term efficiency. Using these innovative approaches could be vital for meeting international targets to repair degraded ecosystems, sequester carbon, and restore biodiversity.
- Many people see reforestation as a quick fix to the climate emergency, but tree-planting projects often fail to put in place the monitoring programs needed to track newly planted forests. Traditionally, forest monitoring has been done by hand, one tree at a time, which is extremely expensive and time-consuming.
- Satellites are mapping and remapping the entire planet daily, providing real-time data that can be used to monitor forests remotely. Drones can fly over or through forests to collect data on tree growth, bridging the gap between on-site measurements and distant satellites.
- Sensors can be installed to monitor individual trees directly, while people can collect and analyze the data electronically from a safer and easier-to-access location. Multiple sensors can form a distributed network that returns detailed information on the growth of each tree within huge reforestation plots.

Air pollution sensors found to store crucial biodiversity data
- A team of scientists have discovered that two air quality monitoring stations in the U.K. also collected DNA samples that could benefit biodiversity monitoring.
- Scientists analyzed DNA samples trapped in the two air pollution sensors and identified 180 taxa of mammals, plants, birds and invertebrates.
- The findings signal the presence of a trove of biodiversity data hidden in air pollution sensors around the world.
- The sampling and analysis of airborne DNA is a relatively new methodology to survey biodiversity; experts say further studies are required to determine its wider applications.

New study identifies mature forests on U.S. federal lands ripe for protection
- A new mapping study conducted by NGOs finds that older forests in the U.S. make up about 167 million acres, or 36%, of all forests in the contiguous 48 states. About a third of this, or roughly 58 million acres, are on federal lands. The rest are controlled by non-federal entities, including large amounts held by private owners.
- Just 24% of U.S. Forest Service and Bureau of Land Management forests are fully protected, with the rest being at various levels of risk from logging, offering the Biden administration an opportunity to more thoroughly protect far more old-growth and mature forests on federal lands in order to help meet U.S. climate goals.
- The new study identified a challenge inherent in this strategy: The majority of federal lands are in the West, but one of the highest concentrations of U.S. mature and old-growth forests is in the Southeast, where most older forests are on private property. Privately held old-growth and mature forests are poorly protected in the U.S.
- If the U.S. wants to broaden its carbon emission reduction strategy, say researchers, then mature forest conservation should include both federal and private holdings. Private forests could be protected via state regulation, utilizing conservation easements and payments for verifiable carbon offsets, along with land trust acquisition.

In Gabon, camera-trap developers find the ideal proving ground for their craft
- Rich in forests and biodiversity, the Central African country of Gabon has long proved a fruitful testing ground for camera-trap technology.
- Snapshots of species once thought extinct in the country, such as lions, have helped inform conservation policy, including the establishment of national parks and protection of vast swaths of forest.
- The wealth of data generated means there are large data sets from various projects that researchers just don’t have the resources or time to sift through — which is why Gabon has also become a testing ground for artificial intelligence tools to aid in that task.
- Key limitations remain the cost of camera traps and the fact that many forms of data capture and analysis simply can’t be done by camera traps or AI, and still require human involvement.

Can conservation technology help save our rapidly disappearing species? | Problem Solved
- Humanity knows, in a best-case scenario, only 20% of the total species on Earth.
- Yet humans have, at a minimum, increased species extinction 1,000 times above the natural extinction rate, raising concerns among field monitoring experts who worry they may be “writing the obituary of a dying planet.”
- The establishment of protected areas often depends on the ability of conservationists to effectively monitor and track land-based species — but is this happening fast enough?
- For this episode of “Problem Solved,” Mongabay breaks down three of the most innovative pieces of conservation technology and how they can advance the field of species monitoring, and ultimately, conservation.

Tech revolution holds world of promise for conservation, but challenges persist
- Technology has rapidly changed the face of conservation and is now at a critical juncture where cutting edge tools are available, but aren’t necessarily as accessible or affordable as they need to be.
- A recent survey by WILDLABS, an online platform connecting conservation technology experts, shows that environmental DNA, networked sensors and artificial intelligence tools are the fields that hold the most promise.
- Yet despite the progress that’s been made, there are still many barriers to accessibility for local and Indigenous communities.
- Experts say collaboration and partnerships between conservationists, tech developers and local and Indigenous communities will be key to ensuring that conservation tech can continue having an impact.

Camera trap study shows conservation efforts ‘are working’ on Costa Rica’s Osa Peninsula: Video
- The largest-ever camera trap study in Central America, on Costa Rica’s Osa Peninsula, has revealed how human disturbance affects where animals live and how they’re grouped.
- Protected areas and healthy forests held a greater diversity of animals as well as larger species like tapirs, jaguars and pumas, while places with more human activity had fewer species, which tended to be smaller, more common animals like opossums and agoutis.
- The camera trap study, begun in early 2018, shows many species have recovered completely in the forest reserves around Corcovado National Park, indicating that conservation efforts over the past 30 years have been largely effective.
- Local conservation groups are now focused on creating wilderness corridors so larger species like jaguars can rebound in neighboring forests.

Hungry like the maned wolf pup: Clips give rare glimpse of elusive canine
- New camera-trap clips show three maned wolf pups nursing and eating regurgitated food from their mother.
- This is the first time this behavior has been observed and documented in wild maned wolves, experts say.
- Wild maned wolves have recently recolonized Iberá National Park in Argentina, thanks to conservation efforts.

The cat is back: Wild Amur tigers rebound in China, thanks to govt policies
- Camera trap footage taken between 2013 and 2018 revealed that about 55 endangered Amur tigers are now living in northeastern China.
- Experts say the tigers’ reemergence in the region is largely due to Chinese national policies favoring environmental stewardship, including the Natural Forest Protection Project and the establishment of several reserves.
- According to a recent paper, northeastern China could actually support about 310 tigers, including 119 breeding females, if further efforts are taken to minimize human pressures and ecological corridors are established between tiger habitats.
- While tiger numbers are growing in China, the species continues to face threats of poaching, habitat loss and fragmentation, and human-wildlife conflict.

Human impacts leave reefs short on sharks and long on moray eels
- A new study found that moray eels are more abundant on reefs where sharks are absent due to human pressures.
- The paper hypothesizes that moray eels might be benefiting from a reduction in predators and competition for food, although this hasn’t been proven.
- The authors say a lot more research is needed to assess the relationship between sharks and moray eels, and to understand the ecological role moray eels play in the marine environment.

Lasers find forest gaps to aid tree mortality studies in Brazilian Amazon
- Using airborne light detection and ranging technology, more commonly known as “lidar,” a team of researchers remotely studied tree death and canopy gaps across the Brazilian Amazon.
- Gaps in the forest, the researchers found, were mostly driven by water stress, soil fertility, floodplains and forest degradation. The data also pointed to strong correlations between the patterns of tree gaps and water deficit, a lack of water that can slow down photosynthesis.
- In the southeastern and western Amazon, a pattern of 20 to 35% higher gap dynamics emerged, meaning trees are dying and creating gaps more frequently there than in other regions.
- Aircraft lidar is helpful for studying remote areas of the Amazon and could be used effectively to monitor for illegal logging and deforestation, as well as for calibrating satellite technology.

Cat fight: Jaguar ambushes ocelot in rare camera trap footage
- Camera trap footage revealed a jaguar killing an ocelot at a waterhole in the Maya Biosphere Reserve of northern Guatemala.
- While this kind of killing event is considered rare, it can occur when two predator species are competing with each other over resources such as water.
- Prolonged drought, compounded by climate change, may have influenced this event by making water scarcer than usual, according to the researchers who documented the incident.
- However, other experts say that climate change wouldn’t have necessarily influenced this behavior since ocelots and jaguars have lived together for a long time.

The Amazon’s short-eared dog was thought to be a scavenger. Now there’s video
- After installing a camera trap near a dead armadillo, a biologist unexpectedly recorded video of the elusive short-eared dog (Atelocynus microtis) scavenging on the carcass, and subsequently published a field report about the incident.
- While there was previous anecdotal evidence that short-eared dogs scavenge, this field report provides the first published documentation of this behavior, according to its author.
- In general, very little is known about the short-eared dog, including information about the species’ biology and ecology, although researchers are working to fill these gaps.

Don’t cross this tiger mom: Close encounter in Russia’s Far East
- A researcher working for the Wildlife Conservation Society (WCS) in Russia had a close encounter with an Amur tiger and her cub in the Sikhote-Alin Biosphere Reserve in mid-September.
- Amur tigers are considered to be endangered species, with fewer than 600 believed to be living in China and Russia.
- The biggest threat to Amur tigers is poaching, although conservationists say that recent changes in Russian law have made is easier to convict hunters and traffickers.

Paper giant APP linked to Indonesia peat clearing despite sustainability vow
- Greenpeace Southeast Asia has identified nearly 3,500 hectares (8,650 acres) of peatland clearing in pulpwood plantations in Sumatra supplying Asian Pulp & Paper.
- Analysis of satellite imagery showed the clearing began in August 2018 and continued through June this year, despite APP having a “no peatland” and “no burning” policy that it also imposes on its suppliers.
- Greenpeace and local NGO Jikalahari also found evidence of fires in the concessions in question, which appeared to have been set deliberately to clear the land for planting.
- APP has denied clearing the peatland or setting the fires, calling into question the accuracy of the maps used and saying the fires spread from neighboring farms.

Bubbles, lasers and robo-bees: The blossoming industry of artificial pollination
- Ninety percent of flowering plants require the help of animal pollinators to reproduce, including most of the food crops we eat.
- But massive declines in the populations of bees, the most efficient pollinators around, and the rising cost to farmers of renting them to pollinate their crops, has spurred the growth of the artificial pollination industry.
- The technologies being tested in this field include the delivery of pollen by drones and by laser-guided vehicles and even dispersal via soap bubbles.
- Proponents of artificial pollination say it can both fill the gap left by the declining number of natural pollinators and help in the conservation of these species; but others say there may not be a need for this technology if there was a greater focus on conservation.

Camera snaps first ever glimpse of a troop of the world’s rarest gorilla
- A camera in Nigeria’s Mbe Mountains captured the first known images of a large group of Cross River gorillas, including adults, juveniles and babies, according to the Wildlife Conservation Society (WCS).
- It’s estimated that there are about 300 Cross River gorillas left in the world, with about a third of the population living in three contiguous sites in Nigeria, and 30 to 35 individuals based in the Mbe Mountains.
- Due to conservation efforts, no Cross River gorillas have been reported poached since 2012, according to WCS.

Treetop cameras capture first known video of a wild roloway monkey
- Treetop cameras in Côte d’Ivoire’s Tanoé-Ehy forest recently captured the first known video of a wild roloway monkey, a critically endangered species that spends most of its time high up in trees.
- There are only about 300 roloway monkeys left in the wild, and 36 individuals living in captivity, so conservation efforts are paramount to preserve the species, according to experts.
- Conservationists are also hoping to capture video of the critically endangered Miss Waldron’s red colobus monkey, which hasn’t been spotted in 42 years.

Tigers caught on camera lounging in a Jacuzzi-sized watering hole
- Camera traps in Thailand’s Western Forest Complex captured an array of animals, including tigers, a banteng, elephants, sambar and muntjac deer, a wild boar, a long-tailed macaque, a crab-eating mongoose, a crested serpent eagle, a blue magpie, and a jungle fowl.
- The Western Forest Complex, or WEFCOM, is Thailand’s largest block of intact forest, and home to at least 150 species of mammals, 490 birds, 90 reptiles, 40 amphibians, and 108 fish, many of which are threatened and endangered species.
- Poaching and habitat encroachment have placed many species living in WEFCOM under duress, but populations are slowly recovering in response to increased conservation efforts.

Success of Microsoft’s ‘moonshot’ climate pledge hinges on forest conservation
- One mechanism by which the 2015 Paris Climate Agreement incentivizes greenhouse gas reductions is via carbon offsets, payments that compensate nations, states and private landowners who agree to keep forests intact in order to preserve carbon storage capacity and biodiversity.
- But problems exist with forest carbon offset initiatives: corrupt landowners, lack of carbon accounting transparency, and low carbon pricing have caused wariness among investors, and failed to spur forest preservation.
- Now, in a landmark move, Microsoft has pledged to go “carbon negative” by 2030, and erase all the company’s greenhouse gas emissions back to its founding in 1975 by 2050. A big part of achieving that goal will come via the carbon storage provided by verified global forest conservation and reforestation projects around the globe.
- To achieve its goal, Microsoft has teamed with Pachama, a Silicon Valley startup, that seeks to accurately track forest carbon stocks in projects in the Brazilian and Peruvian Amazon, the U.S. and elsewhere using groundbreaking advanced remote-sensing technology including LiDAR, artificial intelligence and satellite imaging.

Tool use in puffins may point to ‘underestimated’ intelligence in seabirds
- A camera trap in Iceland captured video of an Atlantic puffin using a stick to scratch itself.
- The discovery, along with a similar observation in Wales in 2014, is the first evidence of tool use in seabirds.
- The findings suggest that seabirds like puffins may be more intelligent or possess greater problem-solving skills than once thought.

LIDAR technology leads Brazilian team to 30 story tall Amazon tree
- A research team using cutting edge LIDAR technology is mapping the Brazilian Amazon to create a detailed biomass map in order to track the impacts of land use change on forest carbon emissions — data collection required under the Paris Climate Agreement and paid for by the Amazon Fund.
- While conducting their LIDAR survey by aircraft, the study team detected several groves of immense trees on the border between Pará and Amapá states. One individual, a red angelim (Dinizia excelsa Ducke) was recorded as being 88.5 meters (just over 290 feet) tall.
- A team of 30 researchers, guided by riverine community guides, made the arduous journey to the giant tree groves. They found some of the trees growing atop a hill, which is unusual because big tropical trees generally thrive in low places safe from wind. Further research is needed to learn why they grow there.
- The giant trees are more than a source of wonder: each can sequester up to 40 tons of carbon, nearly as much as a hectare (2.4 acres) of typical forest. So, when managing a forest and deciding which trees to cut, it is important to consider tree size. In this particular case, the loss of one giant red angelim’s carbon footprint would be huge.

‘No place to hide’ for illegal fishing fleets as surveillance satellites prepare for lift-off
- A low-cost satellite revolution is paving the way for real-time monitoring of fishing vessels using synthetic-aperture radar (SAR).
- SAR allows researchers to monitor ‘dark vessels’ that aren’t transmitting Automatic Identification Signals (AIS) location data.
- Disabling or manipulating AIS transmitters is a tactic commonly used by vessels engaged in illegal fishing activity.

Tests show multi-rotor UAVs can improve cetacean behavioral studies
- Researchers assessing the utility of small, multi-rotor unmanned aerial vehicles (UAVs) to survey and study humpback whales found that video data collected from a UAV improved upon data recorded by an expert observer from a research vessel, a standard technique.
- The observer mischaracterized certain behaviors, primarily socializing and nurturing, as other activities, such as traveling or resting, that the aerial viewpoint of the UAV captured clearly, even when the animals were below the surface.
- The whales did not show changes in behavior when the UAV approached or remained present at 30 meters above them.
- Their results suggest that small UAVs add value to cetacean behavioral research as a non-invasive research tool that can capture information that is otherwise difficult to detect from the angle and distance of a ship or shore observer.

Baby whale wears a camera, reveals its travel and nursing behavior: video
- A video taken by a camera carried by a baby whale shows underwater nursing behavior from the calf’s perspective.
- The CATS Cam camera used in the filming incorporates multiple environmental sensors, such as depth and temperature, as well as movement and acceleration by the calf.
- The unusual perspective may help researchers better understand the nursing process of a baby whale, including surfacing to breathe while its mother remains underwater and suckling from mammary slits on each side of its mom.

Conservation tech prize with invasive species focus announces finalists
- The Con X Tech Prize announced its second round will fund 20 finalists, selected from 150 applications, each with $3,500 to create their first prototypes of designs that use technology to address a conservation challenge.
- Seven of the 20 teams focused their designs on reducing impacts from invasive species, while the others addressed a range of conservation issues, from wildlife trafficking to acoustic monitoring to capturing freshwater plastic waste in locally-built bamboo traps.
- Conservation X Labs (CXL), which offers the prize, says the process provides winners with very early-stage funding, a rare commodity, and recognition of external approval, each of which has potential to motivate finalists and translate into further funding.
- Finalists can also compete for a grand prize of $20,000 and product support from CXL.

Film that fish: Stereo-video speeds surveys of marine fish communities
- Researchers use underwater visual surveys to assess the sizes of fish in marine communities and their associated habitats, but diver-based data collection is time-consuming and requires expertise, and results may vary among different data collectors.
- A multinational research team recently published the first guide to help researchers using diver-operated stereo-video methods (stereo-DOVs) to standardize surveys of fish assemblages (species and their abundances) and their associated habitat.
- The video provides a permanent, shareable record of each survey transect, including the species and numbers of fish seen, while the stereo option allows researchers to measure fish using overlapping images.
- The guide provides information on appropriate equipment; designing a stereo‐DOV if needed; operating it during underwater studies; processing the video data after collection; and analyzing fish behavior, population features and habitat in the resulting video.

Models, maps, and citizen scientists working to save the Great Barrier Reef
- As global warming drives more events that impact coral reefs, managing the Great Barrier Reef’s resilience demands comprehensive and detailed mapping of the reef bed.
- Available surveys and maps with geographically referenced field data have been limited and fragmented.
- A diverse research team recently demonstrated a successful approach, applying statistics to image data to build predictive models, integrate diverse datasets on reef conditions, and provide a comprehensive map of the Reef that informs reef management decisions.

Lift-off for thermal-imaging system to estimate wildlife populations
- A research team hailed a breakthrough in their imaging system’s ability to detect and identify orangutans in tropical rainforest.
- They now plan for computer algorithms to report back what a thermal camera has seen in real time.
- The researchers believe the system could also be used to spot poachers targeting rare species.

Virtual Reality 360-degree video: An “empathy-generating machine” for conservation outreach?
- New video technology that films in 360 degrees brings viewers into the middle of the action and is set to become a powerful outreach tool to build understanding and empathy for wildlife and wild places.
- Small off-the-shelf cameras rugged enough to film in the wild are relatively inexpensive, easy enough for field researchers and other filming novices to use, and sufficiently sophisticated to collect videos of resolutions higher than 5 megapixels.
- At a recent presentation at National Geographic, four VR-360 filmmakers strongly endorsed the technology as a tool to inspire and nurture empathy in viewers for a range of conservation issues.

Climb confirms that the world’s tallest tropical tree tops 100 meters
- A team of scientists has found and mapped the tallest tree on record in the tropics, standing at more than 100 meters (328 feet).
- Climber Unding Jami with the South East Asia Rainforest Research Partnership scaled the tree and verified its height.
- The structure of the tree, determined from airborne lidar surveys as well as laser scans from the ground and drone photographs, provides insight into why these trees grow so high.

Those kicks were fast as lightning: Kangaroo rats evade deadly snake strikes
- A research team has shown that desert kangaroo rats fend off predatory rattlesnakes through a combination of speedy reaction times, powerful near-vertical leaps, and mid-air, ninja-style kicks.
- Locating snakes through radio tracking and filming snake-kangaroo rat interactions with high-speed video cameras enabled the team to analyze strike and reaction speed, distance and angle the rats moved to avoid being bitten, and aspects of the impressive maneuverability displayed by most kangaroo rats in the recordings.
- About 81 percent of recorded snake strikes were accurate, yet the snake actually bit the kangaroo rat in just 47 percent of the strikes and latched on long enough in just 22 percent of strikes to actually kill and eat the kangaroo rat.
- The slowed-down videos demonstrate the importance of kangaroo rats’ physical features, including long tails and powerful legs, and mid-air maneuverability in escaping predation.

Combining artificial intelligence and citizen science to improve wildlife surveys
- Migratory species play a key role in the health of the Serengeti ecosystem in East Africa, but monitoring their populations is a time- and labor-intensive task.
- Scientists studying these wildebeest populations compared expert observer counts of aerial imagery to corresponding counts by both volunteer citizen scientists and deep learning algorithms.
- Both novel methods were able to produce accurate wildebeest counts from the images with minor modifications, the algorithms doing so faster than humans.
- Use of automated object detection algorithms requires prior “training” with specific data sets, which in this case came from the volunteer counts, suggesting that the two methods are both useful and complementary.

AI and drone-based imagery improve power to survey cryptic animals
- Developing effective management strategies for threatened species like koalas requires knowing where and how many are in a target area, but surveying cryptic low-density animals can lead to variable estimates.
- A recent study has introduced a new automated method for wildlife detection using a pair of object detection machine learning algorithms to detect animals’ heat signatures in drone-derived thermal imaging.
- By understanding error rates of different survey methods and including appropriate technology, the researchers say, wildlife monitoring can become more efficient and effective.

The odor side of otters: Tech reveals species’ adaptations to human activity
- Recent studies of an elusive otter species living in the highly modified mangroves and reclaimed lands on the coast of Goa, India offer new insights into otter behavior that could inform future conservation efforts.
- Researchers have studied these adaptable otters with camera traps, ground GPS surveys, and satellite images; they’re now testing drone photogrammetry to improve the accuracy of their habitat mapping.
- Using data gathered over a period of time, the researchers aim to pinpoint changes in the landscape and, in combination with the behavioral data gathered by the camera traps, understand how otters are reacting to these changes.

A snapshot of camera traps reveals user frustrations and hopes
- A team of camera trapping experts surveyed researchers and conservation professionals to identify limitations to their successful use of remote cameras, assess their wish list of technological developments, and predict what next-generation camera trapping will look like.
- Their recently published study revealed that cost, theft, vulnerability of the cameras to environmental conditions, and several ongoing technical issues may be limiting the effectiveness of this popular technology in providing the utility the users seek.
- The survey respondents offered numerous predictions for next-generation camera trapping, including solar and lithium-ion power sources, a wider range of sensors, and software-driven automation.

The good luck black cat, revealed by camera traps
- Camera traps enabled researchers and a professional photographer to document the presence of a rare melanistic (black) leopard, confirming reports of the cat in northern Kenya.
- Five different remote camera stations, positioned near water sources and trails, recorded the young female leopard over three months.
- The case demonstrates the value of remotely placed sensors in capturing both shy, cryptic animals and rare events in nature, such as melanism, which results from genes producing a surplus of pigment in an animal’s skin or hair so that it appears black.

How do you assess if a reintroduced species is thriving? Listen for it
- Researchers in New Zealand combined sound data from acoustic monitoring devices with species occupancy models to assess the success of translocating an endangered New Zealand bird, the hihi, to invasive species-free locations.
- The scientists say in their paper that advances in acoustic monitoring and statistical techniques have made it possible to infer spatial and temporal changes in population dynamics without needing to track individual animals.
- As wildlife managers increasingly release animals back to their historic ranges, cost-effective, non-invasive data collection, automated pattern recognition, and analysis techniques that predict the likelihood of species occupying a given location over time could improve the success of the reintroduction process.

Camera traps and customary wisdom help redefine bear conservation
- Camera traps set up around a Canadian artic research camp led to the first published documentation of all three North American bear species in the same locations.
- Although more than 90 percent of the 401 bear visits recorded by the cameras were of polar bears, the presence of grizzlies, which have been seen as threatening polar bears, has caused debate among scientists, conservation managers and local communities.
- The camera data did not document interactions among polar, grizzly and black bears, though the researchers say the spatial overlap of the species suggests potential for interspecies interactions to occur, raising questions about how they might affect bear conservation efforts in the future.
- Some conservation managers, aware that their values align with those of the region’s Indigenous communities, are increasingly marrying traditional wisdom to scientific methods to inform their work.

Study finds bears react, then habituate, to drones
- Small drones increasingly serve as tools to monitor wildlife, detect habitat change, or search for poachers, but their use may be stressing out the animals being studied or other species.
- A research team tested whether black bears would habituate to the repeated presence of drones flying overhead and, if so, whether they would remain habituated to additional flights conducted after a break.
- The bears showed an increased tolerance to drone flights in the short term, which they maintained after a nearly four-month pause.
- With the expanding use of drones in wildlife and habitat studies, the researchers expect their findings to help inform best practices that could reduce animal disturbance in the long run.

As animal tagging goes cutting-edge, ethical questions abound
- An increasing number of animal tracking devices, known as biologgers, also measure environmental variables such as sound, temperature, and ocean salinity.
- Data from biologgers complement information on an animal’s movements and help scientists understand its environment, but can have measurable effects on the animal’s behavior or reproduction.
- As the field of biologging rapidly grows, scientists are trying to develop ethical frameworks for applying devices to wild animals.

New space lasers offer best 3D look at global forests yet
- Forest monitoring has increasingly turned to satellites over the past several decades, and 2018 was no exception.
- In the last few months, NASA launched two sensors into space that will play a prominent role in monitoring forest biomass and structure over the next decade: the Global Ecosystem Dynamics Investigation (GEDI) now attached to the International Space Station, and the Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2).
- These two satellites, which in combination provide complete coverage of the planet, are equipped with lidar sensors that record forest structure in 3D, contributing to an ongoing wave of large-scale forest ecosystem measurements.

Drones with thermal cameras help detect camouflaged species
- Scientists tested the capacity of small drones equipped with thermal cameras to survey European nightjar nests in areas where construction or logging is planned.
- Nightjars use camouflage and cryptic behavior to avoid predation, which makes them difficult to observe on the ground and avoid disturbing, as required by U.K. law. Finding a faster, more cost-effective survey method to detect their presence could help forestry and construction managers comply with regulations more efficiently.
- The scientists say that the drone-thermal camera combination would be suitable for surveying other open-country wildlife, and could be aided by automated analysis of the thermal signatures of target species.

Overseeing this global environmental news empire provides Rhett with a wealth of insight into the science and trends that are shaping conservation.

Eavesdrop on forest sounds to effectively monitor biodiversity, researchers say
- Recording and analyzing forest soundscapes can be an effective way of monitoring changes in animal communities in tropical forests and human presence, researchers say in a new commentary published in Science.
- Bioacoustics, which can be used to cover a vast range of animal groups over large landscapes, can also fill the gap between the bird’s-eye view of satellites and the finer focus of on-the-ground surveys, to give a clearer picture of animal population trends over large landscapes.
- Moreover, bioacoustics has the potential to be an important tool in assessing what’s working and what’s not working in conservation, such as to monitor forests maintained by companies under certification or zero-deforestation commitments.
- The researchers have called for improvements in processing and analysis of huge acoustic data sets, which at the moment are the major bottlenecks in soundscape research.

Top camera trapping stories of 2018
- Camera traps, remotely installed cameras triggered by motion or heat of a passing person or animal, have helped research projects document the occurrence of species, photograph cryptic and nocturnal animals, or describe a vertebrate community in a given area.
- Camera trapping studies are addressing new research and management questions, including document rare events, assess population dynamics, detect poachers, and involve rural landowners in monitoring.
- And with projects generating ever-larger image data sets, they are using volunteers and, more recently, artificial intelligence to analyse the information.

10 ways conservation tech shifted into auto in 2018
- Conservation scientists are increasingly automating their research and monitoring work, to make their analyses faster and more consistent; moreover, machine learning algorithms and neural networks constantly improve as they process additional information.
- Pattern recognition detects species by their appearance or calls; quantifies changes in vegetation from satellite images; tracks movements by fishing ships on the high seas.
- Automating even part of the analysis process, such as eliminating images with no animals, substantially reduces processing time and cost.
- Automated recognition of target objects requires a reference database: the species and objects used to create the algorithm determine the universe of species and objects the system will then be able to identify.

Drone 3D models help assess risk of turtle nesting beaches to sea level rise
- In a recent study, researchers took drone-based images to map the structure of sea turtle nesting beaches in northern Cyprus to determine their susceptibility to flooding from sea level rise.
- Automated drone flights with on-board cameras can record sequences of photos of the surface below, which can be merged in a process called photogrammetry to construct three-dimensional models of the survey area.
- The fast pace of innovation and versatility of drones can improve sea turtle conservation efforts through cheaper, more efficient monitoring.

Hobby-grade drones can monitor marine animals beneath the surface
- Researchers in The Bahamas have been testing just how good drone videos can be for estimating the abundance and distribution of large marine animals found just beneath the ocean’s surface.
- They flew aerial surveys using commercial-grade drones along six tidal creeks facing high and low human impact, to count sharks, rays, and sea turtles — groups that are both threatened and difficult to monitor. The findings from multiple sites suggest that shoreline development negatively affects the abundance and distribution of various marine species.
- The study also showed that using lower-cost consumer drones equipped with video cameras could help researchers effectively and non-invasively estimate abundance of these marine megafauna in shallow waters and compare data across sites.

A monitoring network in the Amazon captures a flood of data
- Cameras and microphones are capturing images and sounds of the world’s largest rainforest to monitor the Amazon’s species and environmental dynamics in an unprecedented way.
- The Providence Project’s series of networked sensors is aimed at complementing remote-sensing data on forest cover change by revealing ecological interactions beneath the forest canopy.
- Capable of continuously recording, processing and transmitting information to a database in real time, this high-tech experiment involves research institutions from three countries and the skills of biologists, engineers, computer scientists and other experts.
- The monitoring system will connect to a website to disseminate the forest biodiversity data interactively, which the researchers hope will contribute to more effective biodiversity conservation strategies.

Peru’s Brazil nut harvesters learn to monitor forests with drones
- Brazil nut and ecotourism concessions in the Amazon maintain intact rainforest, but deforestation by illegal loggers, miners, and agriculturalists threaten the integrity of these lands and the Brazil nut industry.
- The Peruvian NGO Conservación Amazónica – ACCA is training concessionaires and forestry officials in southeastern Peru to fly drones and monitor the properties they manage using drone-based cameras.
- The resulting high-resolution aerial images enable concessionaires to detect and quantify deforestation within their Brazil nut, ecotourism, and other forest concessions and support their claims of illegal activity to the authorities.

For the birds: Innovations enable tracking of even small flying animals
- Advances in satellite communications have revolutionized wildlife telemetry, yet tracking the movements of small animals, especially ones that fly, and marine species, which rarely break the ocean’s surface, has remained a challenge.
- In a November 20th virtual meetup on next-generation wildlife tracking, three speakers introduced developments that have broadened telemetry’s reach to new species and new types of data being collected.
- Recent innovations — including the ICARUS tracking system, hybridization of communications platforms, and miniaturization of sensors — are producing tiny solar-powered tracking tags and tags carrying various environmental sensors that function within private networks flexible enough to use the most efficient of several communications technologies available at a given site.

Virtual meetup highlights networked sensor technology for parks
- To encourage communication between the conservation community and technology developers, the WILDLABS platform began a series of virtual meetups earlier this month.
- Speakers in the first meetup represented three groups developing and deploying networked sensors for improving wildlife security and reducing human-wildlife conflict.
- The three tech developers described lessons they’ve learned on meeting the needs of rangers and reserve managers, using drones to fight poaching, and adapting technology to function in remote areas under difficult conditions.

Camera-wielding robot records effects of pesticide on bees’ behavior
- Bee populations are on the decline, and studies have linked this to the use of pesticides containing neonicotinoid compounds, which can impact insect behavior.
- Researchers built a robotic platform that allowed them to observe the impacts of neonicotinoid compounds on bumblebee behavior inside bee colonies over a 12-day period.
- The robotic observation platform held computer-programmed movable cameras that could monitor up to 12 colonies at a time, which included foraging and nesting chambers with simulated “daytime” and “nighttime” conditions.
- The team found that bumblebees exposed to environmentally realistic amounts of neonicotinoid compounds reduced their nursing and caretaking activities at night and were less able to regulate the colony’s temperature, among other behavioral changes that may impact their population.

Pod-cast: New app streams whale songs for web users in real time
- Researchers have developed a web application to enable citizen scientists to listen for the sounds of a population of killer whales off North America’s northeast Pacific coast in real time.
- A network of underwater microphones will stream sounds from under the sea to citizen scientists, who can then report any unusual noises and help decode orca language.
- The researchers have found that human listeners can readily detect unusual sounds amid a stream of underwater noise, and their participation can complement machine-learning algorithms being developed.

Speed trap: Cameras help defuse human-cheetah conflict in Botswana
- Increases in human-wildlife conflict could undermine Botswana’s conservation efforts, with farmers in some areas shooting carnivores preventatively to protect their livestock.
- Camera traps have helped researchers in Botswanan farmland to monitor cheetahs and other elusive or low-density predators without habituating them to human presence, a key feature in areas where farmers believe they will kill livestock.
- Communicating with local farmers and sharing camera-trap data on cheetahs’ territorial behavior and long-distance travel can help show farmers there may be far fewer individuals than they realize — “the cheetah seen today on one farm may be the same one seen [earlier] several farms away.”

Satellite technology unites Kenyans against bush fires
- The Eastern and Southern Africa Fire Information System (ESAFIS), an online application developed in Kenya, uses MODIS satellite information to detect bush fires in eastern Africa.
- The freely available app maps and categorizes bush fires in near-real time and shows details of each fire , including the time it was detected, its location with respect to towns and protected areas, and its relative intensity.
- By providing an early fire warning system, the system helps forest management authorities respond to fires in their early stages and prioritize limited resources to fire hotspots.

AI simplifies statewide study of leopards in south India
- A six-year study of leopards in the wildlife-rich southern Indian state of Karnataka, using grids of motion-sensor camera traps across the state, suggests the big cats are thriving in a variety of habitats and land uses.
- The researchers’ use of machine-learning algorithms significantly reduced the workload needed to identify 363 individual leopards from the sample’s 1.5 million camera-trap images. The figure indicates there are an estimated 2,500 leopards living in Karnataka.
- Although a forest department official said the state was unlikely to expand its protected forests in the foreseeable future, the researchers said such a policy was necessary for leopard conservation, stressing that the proximity of natural landscapes to agricultural fields allows leopards to use those unprotected areas.

How porpoise sounds helped researchers test acoustic devices
- A team of scientists used playbacks of recorded and artificial porpoise clicks to develop an adaptable method to assess the area in which acoustic monitoring devices can reliably detect these sounds
- Researchers need to know how far away they can expect acoustic data loggers to capture the sounds of target animals to estimate the density of those animals from the recordings.
- The cetacean data loggers could reliably detect the click signals up to nearly 200 meters (656 feet), which translated to a circular sampling area of 11 hectares (27 acres) per device.
- The data logger algorithms could correctly classify the clicks as porpoise sounds only up to 72 meters (236 feet), representing a reliable sampling areas of just 1.6 hectares (4 acres) that could be used to estimate the density of a specific species, an issue affecting researchers working with more than one echolocating species.

The Osa Camera Trap Network: Uniting people to monitor biodiversity
- The Osa Camera Trap Network monitors big cats and their prey on public and private lands across Costa Rica’s Osa Peninsula.
- Concern about connectivity for apex predators between Corcovado National Park and mainland Costa Rica has encouraged the participation of a diverse cadre of stakeholders that has broadened the scale of the project.
- Clear communication, together with a few photos of resident jaguars, have allowed the network’s 23 institutions and communities to install and maintain more than 200 cameras providing the baseline data needed for long-term monitoring of the area’s mammals.

Machine-learning app to fight invasive crop pest in Africa
- To monitor the invasive fall armyworm caterpillar in Africa, the UN’s Food and Agriculture Organization and Pennsylvania State University have collaborated on an AI add-on to FAO’s existing phone app to help farmers detect agricultural pests.
- The fall armyworm, an invasive pest of over 80 plant species, is native to the Americas but reached Africa in early 2016 and has wreaked havoc on their maize, threatening food security.
- The add-on, called Nuru, identifies leaf damage in photos taken by farmers and sends information to authorities to help monitor the presence of the pest.
- Detecting the pest quickly can help reduce unnecessary pesticide use that can damage human and ecosystem health.

The iNaturalist species data sharing platform reaches one million users
- The iNaturalist species data-sharing platform reached a milestone earlier this month with its one millionth observer.
- The 10-year-old platform and mobile app use several smartphone technologies, crowd-sourced data, and artificial intelligence to help observers identify the species of plants and animals they see.
- Co-founder Scott Loarie highlighted the rapid progress in computer vision technology as a surprisingly helpful technology that complements crowdsourcing to speed the image identification process for a large number of photos, though it has also introduced other concerns, including how to maintain high data quality.

For an Amazon tribe, phone cameras shine a light on their wildlife
- Armed with smartphone cameras, teams of indigenous Matsés people have partnered with North American herpetologists to inventory the reptiles and amphibians of their territory along the remote divide between Peru and Brazil.
- The easy-to-use cameras are robust, small enough to carry while climbing a tree or crossing a stream, store thousands of images, and can be recharged with low-cost solar panels.
- The teams have built a database of more than 2,000 photos, including several new species, and they have expanded the known distributions of other species.
- The long-term project complements rapid ecological assessments of a poorly studied region and empowers Matsés elders to pass on their knowledge of the region’s forests to both their families and the outside world.

Tech prize finalists promote collaboration to fight extinction
- Conservation X Labs recently announced 20 finalists for the Con X Tech Prize. As finalists, each project receives $3,500 seed money to develop ideas that may be early stage or broad in scope.
- Among the finalists, the Wild N.O.S.E technology will use olfactory data to detect animals or animal parts and help stem trafficking, and the Right Whale Auto-Detect project listens for and identifies whale calls and then warns ships of whales in the area.

Decoding the language of bats key to their conservation
- Uruguayan scientists have developed a new artificial intelligence algorithm and reference library of bat ultrasound pulses to enable the use of acoustic monitoring of this understudied regional fauna.
- Bats in the Southern Cone are threatened by wind turbines, but their species and sonar emissions differ from other areas, requiring the scientists to build their own acoustic library and predictive algorithms.
- The scientists are collaborating with wind farm companies and international academics to help expand the reference library and improve the algorithm’s accuracy and speed.

Nepali scientists deploy drones to count endangered crocodiles
- Researchers in Nepal used drone images to survey critically endangered gharial crocodiles along the banks of the Babai River, comparing their results to those of multi-team ground surveys.
- Analysis of the drone images produced counts of gharials and mugger crocodiles similar to those of ground survey teams, in less time and at a lower cost.
- The researchers stressed the importance of conducting aerial surveys when environmental conditions are most conducive, such as during the winter months when water clarity in the Babai River enables counts of gharials just under the water’s surface.

Video analysis shows baby birds avoid predators while building strength
- By monitoring grassland bird nests with small video cameras, researchers are learning why and when chicks first venture into the outside world.
- A recent study using video footage showed that nestlings of different species left their nests at different times of the day and over varying lengths of time, from less than one hour to three days for nests with multiple chicks.
- Smaller and more affordable video equipment is allowing scientists to study events, such as bird nest predation and fledging, that happen quickly, generally when humans are absent.

An anti-poaching technology for elephants that is always listening
- Summer 2018 marked the successful completion of the first of three test phases for a new anti-poaching technology elephants can wear on a tracking collar.
- Called WIPER by its development team, the device integrates with wildlife tracking collars and listens for the shockwave, or sonic boom, of a high-powered rifle, a common weapon in the industrial killing of elephants and other megafauna.
- WIPER’s design overcomes two key challenges for high-tech wildlife monitoring: power source (by creating a sleep mode) and cost (by putting designs in the public domain).
- WIPER provides real-time alerts and location data when a rifle is fired within 50 meters (50 yards) of the collared animal. WIPER may not protect the animal wearing it, but it helps security personnel close in on poachers, which may deter future poaching.

Underwater tech unlocks the secrets of The Bahamas’ Exuma Sound
- Scientists in The Bahamas plunged 800 meters (2,624 feet) into the Exuma Sound in manned submersibles for two separate expeditions, carried out in April and August this year.
- Using high-tech cameras, lights and sensors, researchers mapped the underwater terrain, collected samples and obtained footage of rare and undocumented deep-sea species.
- The team hope their research will further conservation efforts in the area, specifically the creation of new marine protected areas that include deep-water habitats.

Fire, more than logging, drives Amazon forest degradation, study finds
- Forest degradation has historically been overlooked in accounting and monitoring carbon stocks.
- A recent study combined ground-based inventory, satellite and LiDAR data to record the loss of carbon due to forest degradation in areas exposed to logging, fire damage, or both, in the arc of deforestation of the southeastern Amazon.
- The study revealed that fire damage causes greater losses than logging, and fire-damaged forests recovered more slowly than logged forests.
- Accurate depictions of both deforestation and degradation are necessary to establish emissions baselines used to inform programs to reduce emissions from deforestation and forest degradation (REDD+).

Automating drone-based wildlife surveys saves time and money, study finds
- Reserve managers have begun to survey wildlife in savanna ecosystems by analyzing thousands of images captured using unmanned aerial vehicles (UAVs, or drones), a time-consuming process.
- A research team has developed machine learning models that analyze such aerial images and automatically identify those images most likely to contain animals, which, according to the authors, is usually a small fraction of the total number of images taken during a UAV survey effort.
- The new algorithms reduced the number of images that needed human verification to less than one-third of that using earlier models, and they highlight the patterns in those images that are most likely to be animals, making the technique useful for image-based surveys of large landscapes with animals in relatively few images.

In Kenya’s Maasai Mara, detection dogs are a ranger’s best friend
- For World Ranger Day 2018, we highlight how detection dogs help rangers keep wildlife — and the rangers themselves — safe in Kenya’s Maasai Mara National Reserve.
- Sniffer dogs search vehicles for ivory and firearms, while tracker dogs enable rangers to track and capture wildlife poachers, thieves in lodges, and cattle rustlers in surrounding villages.
- The dogs have enabled rangers to follow up on intelligence and increase their arrest rate, which they hope will make poaching less viable for local communities and improve security in the region.

Combining aerial imagery and field data estimates timber harvest and carbon emissions
- Researchers used images from LiDAR, a remote sensing technique that produces 3-D depictions of forest structure, to map logging areas—including roads, skid trails, gaps under the canopy, and decks used to store timber—for four timber concessions in Kalimantan on the island of Borneo.
- Pairing the LiDAR data with statistics on the number of trees felled and damaged, the researchers established equations relating the logging area data to both the volume of timber harvested and the resulting greenhouse gas emissions.
- The equations explained up to 87 percent of the variation in the volume of timber extracted.
- Using this method, governments, NGOs, and private organizations can verify timber harvests, formulate future management plans, and estimate harvest volumes and greenhouse gas emissions in other tropical forests, including areas of illegal logging.

Cross-border camera trap research puts wild Amur leopard number at 84
- Scientists working in Russia and China have used camera traps to estimate that 84 Amur leopards remain in the wild.
- Previous studies tracked the cats using their footprints in snow, but the camera trap photographs allowed the researchers to identify individual animals by their unique spot patterns.
- The team found that 20 percent of the Amur leopards appeared on both sides of the border between China and Russia, highlighting the importance of cross-border collaboration.

Online mapping tool tracks land-use changes down to the farm
- The online mapping platform MapHubs stores maps and spatial data and makes them available to user groups for viewing, analyzing, and sharing with stakeholders.
- Users purchase a portal on the platform that allows the group to combine various public and private data sets in one secure place, produce maps, customize how the portal presents information, and receive support when needed.
- Groups have used the platform to identify deforestation from oil palm and cacao plantations and generate products such as time-lapse videos to show how regional deforestation can shift and expand.

‘Better and better’: Thermal cameras turn up the heat on poachers
- The annual Serengeti-Maasai Mara wildebeest migration attracts not just tourists, but also bushmeat poachers, who kill between 40,000 and 100,000 animals along the way.
- In 2016, the Mara Conservancy began using FLIR thermal cameras, which detect heat instead of light, to find and capture poachers at night, when they are most active.
- Thermal imaging, together with a motivated team using high-quality digital radios, has led to the capture of over 100 people and left poachers at a loss as to how they’re being detected.

City forests store rainforest-levels of carbon, study finds
- A recently published study mapped the carbon stores of areas of tree cover in the London Borough of Camden.
- Their results reveal high levels of carbon in Camden’s urban forests – including one area that approaches the carbon density of tropical rainforest.
- They write that although the contribution of urban areas to global aboveground biomass may be comparatively small area-wise, some urban forests have carbon densities comparable to rainforests.
- They say that their results highlight the importance of conserving urban forests as carbon sinks.

Citizen science makes easy work of penguin time-lapse image bounty
- A multinational research team has deployed time-lapse cameras at various penguin breeding colonies to enable a widespread, long-term study of these top predators in the Antarctic ecosystem.
- Volunteers have played a critical role in processing the millions of images resulting from the multi-year study to better understand reproductive behavior and nest success rates across the Antarctic Peninsula, South Shetland Islands, and South Georgia.
- Citizen scientists can help produce large data sets needed to train artificial intelligence algorithms.

Cool birds don’t sing: Study automates acoustic monitoring of songbird migration
- Researchers have developed machine learning techniques to identify bird song from thousands of hours of field recordings, using the information to uncover variations in migratory songbirds’ arrival to their Arctic breeding grounds.
- They deployed automated listening devices during spring over five years, analyzed vocal activity to estimate when birds arrived at their breeding sites, and assessed relationships between vocal activity and environmental conditions.
- They found that the acoustically derived estimates of the birds’ arrival dates were similar to those determined using standard field surveys.
- Temperature and presence of snow affected the birds’ calling patterns, suggesting that collecting corresponding weather data could help avoid bias in using acoustic monitoring to assess population dynamics.

New study provides blueprint to translate satellite data into conservation action
- A new paper offers a protocol to help conservation practitioners integrate forest-monitoring technology with policy to reduce illegal deforestation.
- Public and private entities can more easily access the latest satellite-based remote-sensing technology to rapidly detect new deforestation, prioritize areas for action, identify the causes, and get the information to policymakers without delay.
- The study calls for increased use of satellite technology to improve the monitoring, understanding and communication of deforestation events, as well as increase engagement between government institutions and civil society.

Species recognition shifts into auto with neural networks
- Scientists have shown that a cutting-edge type of artificial intelligence can automatically count, identify, and describe the behaviors of 48 animal species in camera trap images taken in the Serengeti ecosystem.
- The team used a dataset of 3.2 million wildlife images to train and test deep convolutional neural networks to recognize not only individual animals but also what the animals are doing in each image.
- The models performed as well as human volunteers in identifying, counting, and describing the behavior of animals in nearly all the Serengeti camera trap images and also identified those images that required human review.
- The widespread use of motion-sensor camera traps for wildlife research and conservation, coupled with the inefficiency of manual image processing, means successful automation of some or all of the image analysis process is likely to save researchers time and money, as well as catalyze new uses of remote camera photos.

This tiny camera aims to catch poachers — before they kill
- A Tanzanian game reserve has successfully tested the TrailGuard cryptic camera and 24/7 electronic surveillance system to detect and capture wildlife poachers and their snares.
- The system uses image recognition algorithms and real-time image transmission to help the often limited patrolling staff of many protected areas identify and respond to potential poachers along trails before they kill their target animals.
- Despite some difficulties with installation and the algorithms, the TrailGuard units in Tanzania have photographed 40 reserve intruders, including poachers or trespassers, resulting in the arrests of 13 suspects.
- The designers are currently developing a new, lower-cost version of the system to be built later this year that they expect will address the difficulties and be more widely available.

Scientists tackling conservation problems turn to artificial intelligence
- Grantees of Microsoft’s AI for Earth, a program aimed at helping groups address complex environmental problems, met at Microsoft headquarters recently to learn new ways to apply artificial intelligence and cloud computing to their respective projects.
- The program awards grants of access to and training in the company’s cloud-based data storage, management, and analysis to address challenges in four thematic areas: addressing climate change, protecting biodiversity, improving agricultural yields, and lessening water scarcity.
- Grant recipients include teams working on game theory to predict poaching patterns; mining social media photos to determine distributions of particular species; and using machine learning and animals’ acoustic activity to determine effectiveness of conservation interventions.

Vibrations from elephant calls and movements reflect distinct behaviors, study says
- Elephants create inaudible seismic waves when they move or “rumble” that complement the audible sound we hear and that researchers can detect using geophones placed in the ground.
- In a new study, elephants walking or calling through low-frequency rumbles created distinct seismic signals the transmission of which was affected by both local geological structure and low-frequency human-generated noise.
- The research suggests that elephants not only generate these distinct vibrations through their different activities, but can also perceive the difference from at least one kilometer away, suggesting they are using the vibration patterns to communicate.

Cities worldwide use photo app technology to compete in nature observation challenge
- The third-annual City Nature Challenge takes place this weekend, April 27-30, 2018, giving nature lovers in cities around the globe a chance to compete against other cities to see who can make the most observations and find the most species of local plants and animals.
- Residents and visitors from nearly 70 cities will use their smartphones and the iNaturalist app to share photos of their findings over the 4-day period; experts will verify the identifications in early May.
- Organizers hope the event will connect more people to their local urban biodiversity and uncover threatened and invasive species in new locations, to assist local resource managers.

From galaxies far, far away to endangered species just over the hill
