Our relationship with gray wolves is a complicated one, spanning centuries of tension and hostility. In North America, wolves were vilified by European settlers beginning in the 1600s due to the perceived threat that the canines posed to livestock. As a result, wolves became the target of extensive hunting and bounty programs. It wasn’t until 1967 that the species was officially listed as endangered in the U.S. and broadly recognized as an asset to healthy, balanced ecosystems. In the 1990s, wolf populations were reintroduced to wild areas including Yellowstone National Park. Their recovery has been slow, but today there are about 6,000 gray wolves in the lower 48 states — and their numbers are increasing in many parts of their range.

Innovative biochemist Pat Brown is the man behind the Impossible Burger. Now, he's set his sights on a rewilding project on a ranch in Arkansas.
Efforts to break our dependence on large-scale animal agriculture are real… and they're working on two fronts! First to create alternative options for protein that don't come from animals, and second, to transform defunct cattle ranches into revived forested ecosystems.
Scientist Pat Brown has made a name for himself in biochemistry, and more recently in the initiative to reduce humanity’s reliance on animal agriculture. Throughout his journey, he’s championed one particular philosophy: “Blast Ahead!”
Biology Pat Brown has influenced the fields of biochemistry, virology, and genomics throughout his career. Now, the renowned scientist sets his sights on the largest problem of all: climate change.
Bringing biodiversity back to a clearcut ranch in Arkansas is a daunting task, but the mission is clear: use trees and native plants as powerful tools for capturing and sequestering carbon.
It was a late-career epiphany that led “wacky genius” Pat Brown to abandon his academic career and commit himself to fighting global warming and biodiversity collapse. He did it, against all odds, by developing a surprising product: the revolutionary and delicious plant-based Impossible Burger.
Two Wild Hope episodes filmed in Gorongosa National Park and produced by NEWF African Science Film Fellows provide a model for empowering local film crews.
The red-cockaded woodpecker, a longleaf pine specialist that lives in the southeastern U.S., was one of the first species listed under the Endangered Species Act of 1973.

Hrishita Negi is a Ph.D. candidate at Clemson University undertaking her research in the globally recognized tiger landscape of Central India.
AI-enabled cameras are being deployed in a part of India that has the highest concentration of tigers on Earth. These trail cams don’t just take a photo of whatever passes by, but analyze it to identify whether it’s a tiger.
Dr. Hrishita Negi grew up watching wild tigers. Her father, Himmat, worked in tiger conservation for decades, contributing to India’s success in doubling its tiger population over the past 50 years.
Tigers are one of the most iconic faces of wildlife conservation worldwide. These species are still endangered, but indeed on the rise — although it wasn't long ago that tiger populations teetered on the edge of extinction.
The Klamath River dam removal — the largest such project in U.S. history — is nearing completion. Soon, salmon will swim freely in the river and its tributaries for the first time in over a century.
In the northeastern part of India, the population of greater adjutant stork had declined to just 115 birds — until biologist Purnima Devi Barman launched a grassroots effort to do bring the species back from the brink.
When an animal feeds primarily on dead or decaying matter, it is known as a scavenger. Scavengers — like vultures, hyenas, and raccoons — often have bad reputations due to their association with garbage and death. But they are actually an essential part of a functioning ecosystem. Scavengers are nature’s cleanup crew, eating parts of […]
The IUCN Red List of Threatened Species, often referred to simply as “the Red List,” ranks how close some 163,000 plants, animals, and other species are to extinction. Using the latest research, scientists assign a status to each listed species, ranging from “Least Concern” to “Endangered” to “Extinct.” The Red List was established in 1964 […]
To help protect an endangered stork, biologist Purnima Devi Barman provided looms and training to local women to create textiles and clothes that feature the bird.
The greater adjutant stork is one of the largest — and rarest — storks on earth. But locals in one of their last strongholds in Assam, India considered them to be a bad omen until Purnima Devi Barman revitalized their public image.

For over 15 years, Bryan has been a leading scientist documenting the link between lead-based ammunition and ingestion in wildlife. He co-founded and is Director of Sporting Lead-Free to promote an unbiased, non-political message within our community about the benefits of using lead-free sporting options to preserve both our hunting heritage and amazing Wyoming wildlife.
Conservationist and hunter Bryan Bedrosian started Sporting Lead Free to offer a solution to the problem of lead poisoning in eagles: advocating for the use of non-lead bullets as a permanent substitute for traditional lead ammunition.
Nearly half of all golden eagles and bald eagles in the U.S. have elevated lead levels in their bodies. This lead poisoning comes from the bullets used by hunters — not because the bullets harm the eagles directly, but the birds do scavenge on “gut piles” laden with lead fragments left behind after successful hunts.
After years spend researching local wildlife, like the iconic cougar P-22, biologists around Los Angeles pinpointed the vital location for a wildlife crossing to be built to restitch an entire ecosystem.
At the age of 18, Boyan Slat founded The Ocean Cleanup and set out to clean plastic from the Great Pacific Garbage Patch. Ten years later, the team is installing catchment systems at the mouths of rivers to stop plastic pollution of the seas at their source.
Black-footed ferrets are still alive today thanks to the combined efforts of scientists, zoos, tribes, and other partners across North America. The work hasn’t been easy — it’s involved a decades-long captive breeding effort, wild releases at 30 different grassland sites, and even the development of a vaccine to protect against plague! It’s been a […]
Black-footed ferrets nearly went extinct several times in the 20th century. Today, the current largest threat to their survival is a non-native disease called sylvatic plague.
When plowing, poisoning, and non-native plague wiped out nearly 95% of prairie dogs, the ecosystem collapsed around them. Today, conservationists control the disease by providing vaccine-laden treats called “Fip Bits” to help the prairie dogs — and those that depend on them — finally rebound!
Golden eagles are powerful enough to hunt prey as large as deer, but they’re falling victim to deadly lead poisoning introduced to the wild by another potent hunter: us.
Black-footed ferrets have come back from near extinction thanks to breeding, cloning and reintroduction programs that have brought them back to the western prairie. Now, these wild populations are threatened by a plague that targets the prairie dogs they depend on for food — and even the ferrets themselves.
With over 25 years of experience in the wildlife field, Kristy Bly’s expertise is on the conservation and restoration of black-footed ferrets, black-tailed prairie dogs, and swift fox in the North American Great Plains.

Humpback whales are truly a global species. These mammals have one of the longest migrations around, traveling up to 10,000 miles in a single year — and their beautiful, complex songs are heard by sailors and tourists in every corner of the globe.
Sea otters are a marine mammal beloved by many, but it wasn't long ago that they teetered on the brink of extinction. The international fur trade decimated sea otter populations starting in the 1700s, and by the early 1900s, their wild population fell to less than 1% of their original numbers.
More than 35% of land in Belize is protected, and that’s been good for jaguars that live in these refuges — but for populations to thrive, the cats need to move from one safe area in the north to another in the south across a landscape of farms and towns.
Conservationists worldwide use camera traps to study the movements of wild animals. In Belize, they’ve deployed one of the longest-running grids of cameras on the planet to track the hidden lives of jaguars and to focus protections in the dwindling rainforest.
Jaguars are top predators that need large spaces in which to live and hunt. In Belize, 35% of the land has been protected—but these areas are divided into two large clusters, connected by a crucial and dangerous bottleneck that the cats must navigate to survive.

Brazil has over a million miles of roads, and Fernanda Abra has devoted herself to making them less dangerous to local wildlife and biodiversity.
With just a few changes, you can transform your yard or balcony from a wildlife desert into a wildlife sanctuary. And, if you convince your neighbors to do the same, you could even make your neighborhood into a habitat corridor for wildlife!
Just like humans, wild animals often need to cross busy roads as they roam. But unlike us, they can’t rely on stoplights and crosswalks. That’s where wildlife crossings come in.
Fernanda Abra is a biologist with a Ph.D. in Applied Ecology and is currently a postdoctoral researcher at the Smithsonian Conservation and Sustainability Center.
Wildlife corridors are an invaluable conservation tool. These ribbons of habitat connect landscapes fragmented by human development or roadways, giving animals the ability to roam in search of food, water, and mates.
The Brazilian treetops are full of creatures like monkeys and sloths living high above a forest floor segmented by dangerous roadways. The Via Fauna team is installing arboreal crossings made of cheap, local materials to reconnect the forest canopy — and allow these creatures to once again move freely throughout their landscape.
Brazil has more biodiversity than any other nation on Earth, but it also has more than a million miles of roads. Biologist Fernanda Alba and her team are establishing underpasses across the country that allow big terrestrial animals — to date, the team has documented over 40,000 safe wildlife crossings.
In order to scale up reforestation, Mauricio Ruiz and his organization ITPA have partnered with the drone fleet at MORFO. Each drone can plant up to 50 hectares of forest per day, which is 50 times faster than planting by hand.
In the past 40 years, golden lion tamarins became a symbol of conservation success when 150 zoos worldwide assisted a breeding and reintroduction program that brought their numbers in the wild from 200 to over 3700. Then, yellow fever jumped from humans to the primates and began to decimate their population—taking a third of the population in just two years.
Golden lion tamarins live only in small fragments of the Atlantic Forest. In 2021, an outbreak of yellow fever took nearly one third of the already endangered population, but teams were able to modify a vaccine for humans to help immunize the population against future outbreaks.
Golden lion tamarins were nearly wiped out in the 1970s, but worldwide efforts by 150 zoos helped bring the species back from near-extinction. Today, local conservationists are expanding the forests in Brazil, and the wild population has grown from under 200 to now over 4800 tamarins!
Conservationists are hard at work protecting golden lion tamarins and other wildlife from extinction, and now you can help them from the comfort of your own home.
Andreia started working with the conservation of the golden lion tamarin in 1983 as a volunteer in environmental education actions. In 1984, she became part of the golden lion tamarin reintroduction team. She is currently the coordinator of the field management of golden lion tamarins.

Plants can’t move on their own, so they usually need a little help to spread their seeds far and wide. Animals that scatter these seeds — often by eating the fruit and pooping out the remains — are known as seed dispersers.
Alexandra Pires is currently an associate professor at the Federal Rural University of Rio de Janeiro, where she teaches the subjects of Natural Resources Conservation and Fauna Management.
Marcelo Rheingantz is a biologist at the Institute of Biology, Federal University of Rio de Janeiro and Executive Director of Refauna. He has dedicated his research career to the ecology and conservation of vertebrate populations in Brazil and South America.
In 2010, Fernando launched the concept of refaunation, and from then on coordinated the Refauna project, which reintroduced populations of agoutis, howler monkeys and tortoises in the Tijuca National Park, in Rio de Janeiro.
To restore the park to its former glory, researchers knew which animals needed to be reintroduced: monkeys, rodents, tortoises, and even dung beetles all played crucial roles in keeping the forest healthy.
Agoutis are large, adorable rodents found in Central and South America – and they’re critical players in keeping forest ecosystems healthy.
Brazil is a trove of biodiversity — habitats like the Atlantic Rainforest, urban forests like Tijuca National Park, and more coastlines, rainforests, and rivers that are rich with endemic plants and wildlife.
Over 50 species of honeycreeper once lived in Hawai’i, but now only 17 species remain after battling against invasive species and habitat loss. Today, even those survivors are threatened further by avian malaria. To stop the disease, conservationists use innovative techniques to suppress the population of the invasive mosquitoes that spread it.
Millions of years ago, a single rosefinch species arrived on the Hawai’ian islands and evolved into over 50 species of honeycreepers — a phenomenon known as adaptive radiation.
Hawai’i is home to a broad, beautiful array of birds species found only on its islands—like the stunningly diverse honeycreepers, many on the border of extinction. Now, a local team is removing invasive predators, restoring habitats, and battling mosquito-borne diseases to protect honeycreepers from their latest threat: avian malaria.
In addition to the impact of avian malaria, Hawai’i’s endangered honeycreepers are threatened by habitat loss and invasive predators — two problems that harm native bird populations everywhere, likely in your own back yard. Whether you’re looking to help Hawai’i’s birds, or if you’re hoping to make a difference to protect birds locally, the solutions […]
New tracking technologies are uncovering the flight paths of endangered shorebirds — and the obstacles they face along the way.
The endangered wedge-tailed shearwater — also known as the ‘ua‘u kani — was in critical danger after many nesting sites in Hawaii were overrun by predators like weasels, rags, or feral cats. Fortunately for the birds, locals banded together to protect nesting sites and the local population went from just 30 nesting birds to more than 3000!
A group in Maui has restored a safe haven for endangered seabirds to come home and nest: it’s completely fenced-off from predators and restored with native plants, but the birds still need some convincing! The team is using decoy “neighbors” and audio recordings of bird calls to make the seabirds feel at home — and at long last, the colony is growing!
All around the world, seabirds provide a critical link between land and sea. On Hawai’i, ecologists are working to protect two vital shearwater species that helped life first take hold on these islands.
A common conservation technique on islands is the creation of predator-free zones to exclude invasive species, from mice to feral pigs, from recovering habitats.
The bald eagle has been a national symbol of the United States since 1782 — but not that long ago, this iconic species was on the verge of a complete extinction.
Researchers are trumpeting a welcome piece of news for African elephants. In the last 25 years, populations in southern Africa have reversed their declines, and even started to grow, according to a new study in Science Advances.
Coral reefs around the world are threatened by rising ocean temperatures, but hope is growing off the coast of Hawaii. There, researchers at the Coral Resilience Lab selectively breed corals to withstand ever-increasing amounts of heat stress.
This community in Hawaii is rallying together to study and protect local corals. Students, volunteers, and scientists work to collect and categorize fragments broken off from the reef, which then become candidates to breed before the new coral is reintroduced back into the ocean.
Corals are vital to ocean health, but they’re susceptible to rising water temperatures and can “bleach” under too much heat stress. Hawaii’s Coral Resilience Lab is breeding corals that are resilient to these hotter ocean temperatures – then they populate reefs with new corals that can finally beat the heat.
Coral reef bleaching stands apart as a crisis with innovative, long-term solutions.
