Join host Jeff Corwin on an adventure across the Great Plains, exploring the vital connection between species. He assists Native American tribes in re-establishing bison herds, a keystone species that once shaped the ecosystem. Historically, bison were nearly wiped out by western expansion, devastating both the plains and tribal cultures that depended on them.

The loss of bison had ripple effects, impacting predators, scavengers, and species like black-footed ferrets. Conservationists, led by the Intertribal Buffalo Council, are working to restore at least ten large herds. This effort not only revitalizes the environment but also helps Native American communities reconnect with their cultural heritage, ensuring the survival of the Great Plains ecosystem.

Promoting walkability enhances citizen well-being, fosters business, and creates more liveable urban environments by encouraging walking and biking over driving.

City planner and urban designer Jeff Speck champions walkability and sustainable design. He is the bestselling author of "Walkable City: How Downtown Can Save America, One Step at a Time."

This video, featuring Jeff Speck, was recorded on April 8, 2015, in Lahti, Finland. The event was organized by Aalto University Professional Development, The Regional Council of Päijät-Häme, and the City of Lahti, with partial funding from the European Regional Development Fund.

Join Jeff Corwin as he explores climate change impacts, from California's drought-stricken Sierra Nevada and the Caldor Fire's aftermath, where he meets firefighters, to Washington State. There, he highlights conservation efforts for the resourceful American beaver and the endangered Pygmy rabbit.

In Washington, Corwin joins the Tulalip Beaver Project, which humanely relocates beavers from conflict areas. Beavers are vital ecosystem engineers, building dams that increase water storage, filter pollutants, promote biodiversity, and create crucial salmon habitat. Nearly hunted to extinction, these resilient animals are now recovering, with the Tulalip Tribal Community leading successful wildlife management and research efforts.

Join host Jeff Corwin to explore the remarkable comeback of the American crocodile. Once near extinction with only 100 adults, their population now exceeds 2,000 in South Florida, largely thanks to an unexpected sanctuary: the Turkey Point nuclear power plant. Its secure 6,000-acre network of cooling canals provides an ideal nesting habitat, a "nuclear headstart program" supported by Florida Power & Light and Defenders of Wildlife.

Conservationists monitor and tag hatchlings before releasing them, ensuring the health of these apex predators. Protecting crocodiles is vital, as their thriving population signifies a healthy broader ecosystem. Learn more about wildlife conservation at www.defenders.org/wildlifenation.

Join Jeff Corwin on an Alaskan adventure to conserve North America's birds. He explores the Tongass National Forest, a vast old-growth temperate rainforest critical for species like the goshawk

Join Jeff Corwin on an Alaskan adventure to conserve North America's birds. He explores the Tongass National Forest, a vast old-growth temperate rainforest critical for species like the goshawk and vital for carbon sequestration. This unique ecosystem supports diverse wildlife, despite past logging impacts.

Corwin also visits the Alaska Raptor Center, where he helps rehabilitate and release a young bald eagle named Diesel. Rescued after being hit by a car, Diesel's recovery highlights the center's work in returning iconic raptors, including bald eagles and goshawks, to their natural habitat.

Jeff Corwin explores the Great Plains' interconnected species. He aids bison re-establishment with Native American tribes and conserves black-footed ferrets, once thought extinct. Ferrets critically depend on prairie dogs, a keystone species decimated by habitat loss and Sylvatic plague, nearly causing their extinction. The species was famously rediscovered by a dog named Shep.

Conservation efforts involve canine teams, like Melissa Steen and Tule, locating ferrets in prairie dog burrows. Spotlight teams, including Chamois Andersen, then find and trap ferrets at night. Biologists like Jessica Alexander collect vital data and administer life-saving vaccines against Sylvatic plague, ensuring this fragile population's survival.

Join host Jeff Corwin on an adventure across central Florida, exploring the Silver and Ocklawaha Rivers, vital habitats for manatees. These gentle giants face severe threats, including habitat

Join host Jeff Corwin on an adventure across central Florida, exploring the Silver and Ocklawaha Rivers, vital habitats for manatees. These gentle giants face severe threats, including habitat loss, dangerous cold snaps, and harmful algae blooms destroying their food sources. Tragically, manatee deaths are at an all-time high, impacting Florida's environmental integrity.

Conservationists, including Defenders of Wildlife, are racing to save this iconic species. A key solution involves restoring natural warm water habitats and removing man-made barriers like the Kirkpatrick Dam. A free-flowing Ocklawaha River would grant manatees access to essential warm springs, ensuring their survival and promoting coexistence with Florida's natural environment.

Host Jeff Corwin celebrates the Endangered Species Act (ESA), landmark 1973 legislation protecting vulnerable wildlife and ecosystems. The bald eagle, once near extinction, exemplifies the ESA's success, having recovered and now thriving across the U.S.

The ESA also protects sea turtles, with Florida's beaches being globally vital nesting sites. Conservation efforts, like Boca Raton's beachfront parks, are crucial. While only 1 in 10,000 hatchlings survive to adulthood, protecting their habitat allows these keystone species to flourish. All six sea turtle species nesting in America are protected by the ESA.

Join host Jeff Corwin in Central Florida as he helps rescue threatened gopher tortoises from new real estate developments. Florida's rapid growth, with 1,000 new residents daily, leads to habitat

Join host Jeff Corwin in Central Florida as he helps rescue threatened gopher tortoises from new real estate developments. Florida's rapid growth, with 1,000 new residents daily, leads to habitat destruction. Alarmingly, older permits still allow developers to bury tortoises alive, along with the over 360 other species that rely on their burrows.

Gopher tortoises are vital "nature's engineers," digging extensive underground tunnels that provide essential shelter from weather, fires, and predators for countless creatures. Corwin, alongside experts from Defenders and Saving Florida's Gopher Tortoises, meticulously excavates these animals from development sites to prevent them from being entombed.
