The Living Planet Index (LPI)—essentially the S&P 500 Index for wildlife—documents the populations of more than 3,000 wild species. And for the first time, species number less than one-half what they were in 1970.

To increase chances of conservation success, we must understand traits that make an individual species especially resilient or vulnerable to changes in climate. Different species will be affected in different ways; sometimes negatively, but not always.

New research mapping a range of oil spill scenarios in the Canadian Beaufort Sea finds that a spill would likely reach the U.S. shorelines of Alaska and could affect the local communities and wildlife living there.

WWF has found a way to protect the snow leopard while also benefiting nomadic herders. As part of the USAID-funded Conservation and Adaptation in Asia’s High Mountain Landscapes and Communities (AHM) project, local herders like Byambatsooj are now being trained and equipped to collect basic data on the remote mountains they know better than anyone else.

In a groundbreaking study, a WWF-led team discovered Africa’s longest land mammal migration. The migration of Plains (or Burchell's) Zebra stretches from Namibia to Botswana—a distance of more than 300 miles roundtrip.

WWF scientists spent two weeks in April on a research expedition to the islands of Arctic Norway to study polar bears and their habitat. They gathered data on 53 bears total and placed GPS collars on seven females. 

About a year ago, WWF received a Google Global Impact Award grant to launch WWF’s Wildlife Crime Technology Project. Today, the project is literally taking flight.

In the most recent migration, fewer of the orange- and red-winged monarchs made it to the end of the journey than ever before. The monarch butterfly population in Mexico was the lowest ever since 1993.

Camera trap images of two snow leopard cubs tussling and tumbling in eastern Russia indicate a potential resurgence of a once-decimated population.

After an ongoing project tracking elusive snow leopards in a remote area of northeastern Nepal, a government-led project team that included WWF succeeded in fitting a satellite-GPS collar on one of nature’s most elusive big cats on November 25.

The saola—one of the rarest and most threatened mammals on the planet—was photographed in Vietnam for the first time in 15 years by a camera trap set by WWF and the Vietnamese government’s Forest Protection Department.

We know very little about the wildlife and habitat of the Siberian coast, and so WWF teamed up with Canon on a research expedition to learn more.

WWF is tracking the movements of yellowfin tuna in the waters off the Philippines in the Coral Triangle. By gathering more information on the movements of these tuna, we can improve management of the tuna fishery.

WWF places satellite tags on marine turtles in many areas around the world. The information collected from the tags helps us to design better management strategies for their conservation, such as creating marine protected areas for important feeding areas or addressing threats to nesting beaches.

The percentage of forest occupied by monarch butterflies in Mexico, used as an indicator of the number of butterflies that arrive to that country each winter, reached its lowest level in two decades.

Surveying the coral reefs of the Raja Ampat islands, WWF's Helen Fox works to protect marine areas for generations to come.

The ovulid sea snail boasts a remarkable ability to camouflage itself by taking on the appearance of its favorite food—corals. A new underwater survey by WWF and other scientists recently found at least 25 different species of these beautifully colored and patterned snails in an area of the Coral Triangle. The two-and-a-half-week survey was part of a scientific expedition to explore the underwater world of Tun Mustapha Park—a proposed marine protected area.

For the endangered animals of our planet—like the rare and regal snow leopard—climate change means much more than hotter days and intensified storms. These creatures face the prospect of a significant transformation of the habitats that sustain them.

Forget “the dog ate it.” I heard the most memorable excuse for missing homework when I was a high school teacher in Vanuatu—a country of 83 islands in the South Pacific. “I was leaping from a 30 foot wooden tower with only vines attached to my ankles,” explained my student, Ruben Bong.

WWF and six other NGOs announced the Freshwater Fish BioBlitz on February 2, 2014. This new digital platform enables anyone with a camera to contribute to freshwater conservation.

As a specialist in mapping, Gregg Verutes never expected his work to translate quickly and dramatically into conservation victories on the ground. But one map he created had stark and immediate impact. The depiction—of Belize’s coast overlaid with a black patch the size and shape of the Gulf Coast oil spill—impressed on average Belizeans just what was at stake in an upcoming referendum on whether to allow further oil exploration and drilling in coastal waters.
