New York Harbor was a haven of incredible underwater biodiversity—until centuries of pollution turned it into a cesspool. Today, an alliance of architects, restaurateurs, scientists, and high school students is working to restore the harbor and protect the city from climate change. At the heart of the effort is a tiny creature with an outsized talent for cleanup: the extraordinary oyster.

The surprise return of beavers to the British countryside brings benefits and controversy for humans and wildlife alike. The work of these famously busy rodents increases local biodiversity, reduces storm-induced flooding, and restores wilderness to a highly manicured landscape. It also injects some chaos into the lives of the beavers’ human neighbors.

At the Ft. Bragg Army base in North Carolina, an improbable alliance is giving the endangered red-cockaded woodpecker a new lease on life. After a clash between U.S. Fish and Wildlife and the U.S. Army revealed that low-grade forest fires sparked by artillery and tracers inadvertently created excellent woodpecker habitats, the two sides joined forces to monitor and protect the birds on the base.

Ecuador is one of the most biodiverse places on the planet, yet its wild spaces are also among the most threatened. In 2008, the country became the first nation in the world to enshrine the “rights of nature” in its constitution—granting wild species their own legal rights to exist.

Ten years after the largest dam removal in history—on the Elwha River, in Washington State—scientists are chronicling an inspiring story of ecological rebirth. Recovering salmon populations are transferring critical nutrients from the ocean into the forests along the Elwha’s banks, enriching the entire ecosystem.

Decades of war and unsustainable agriculture have stripped almost half the trees from the rainforest atop Mozambique’s Mount Gorongosa. The devastation threatens the watershed that sustains life in nearby communities and in Gorongosa National Park. Now, park experts and local farmers are uniting to plant a new shade-loving cash crop—coffee—that will help restore the forest.

The axolotl—an amphibian with incredible regenerative abilities—is ubiquitous in pet stores, science labs and pop culture, yet almost extinct in the wild. Now, scientists and farmers in Mexico City are using ancient Aztec farming techniques to secure the creature’s future. Meanwhile, another team is partnering with salamander-breeding Dominican nuns to save a closely-related species.

Dogs are often thought of as humans’ best friends. But in Australia, they’re also being enlisted to save other species. Canine conservationists—and their sensitive noses—are helping researchers locate dwindling populations of elusive koalas as their habitats get fragmented by urbanization and devastated by wildfires.

David Attenborough presents seven of the most remarkable animal songs found in nature and explores the significance of these songs in the lives of their species.

A story of hope in troubling times. The discovery of a coral reef in Belize and Guatemala, larger than the size of Manhattan, marks a new chapter in understanding corals and fish that depend on each other and in saving coral reefs worldwide.

Embark to Niagara Falls and witness its stunning beauty and a wide variety of wildlife—mammals, birds, and reptiles— that call it home. Through the eyes of passionate scientists, uncover a complex world forged by stone and powered by water.

Discover how tiny hummingbirds influence their many flowering kingdoms and their ripple effects on macaws, quetzals, monkeys, tapirs and more. Set in the exotic landscapes of Costa Rica.

Join scientists and researchers across the globe as they go to extraordinary lengths to understand wild dogs. See the groundbreaking discoveries that are crucial to saving this incredible animal family, such as the vets treating captive African wild dogs suffering from “broken heart syndrome.”

How do wild dogs survive and thrive in the wild? Discover the secrets to their success, from black-backed jackals that leap skywards to catch prey to agile gray foxes that climb high into the trees.

Meet the many species of canids, the family of wild dogs. They are the most widespread carnivores on the planet.
