Host Jeff Corwin returns to Massachusetts, joining Dr. Lindsay Rosa of Defenders of Wildlife at the New England Wildlife Center. The center provides vital veterinary care for sick, injured, and orphaned wildlife, from raccoons to owls. Corwin and Rosa highlight the surprising biodiversity of New England and the challenges species face due to human encroachment and pollution.

They observe the rehabilitation of a swan suffering from lead poisoning, a common issue from fishing sinkers and shotgun shells. The team successfully treats the swan and later releases a recovered barn owl into a protected habitat. This experience underscores the critical need for conservation efforts and mindful coexistence to protect our wildlife neighbors. To learn more, visit www.defenders.org/wildlifenation.

Urbanist Jeff Speck addresses the problem of suburban car dependence, which he calls "a gas-belching, time-wasting, life-threatening prosthetic device." He proposes making cities more walkable and pleasant to free people from reliance on cars.

Speck highlights Portland, Oregon's early commitment to bicycles and walkability in the 1970s as a successful model. This TEDTalks presentation, published on October 14, 2013, advocates for Portland's "new way" of urban development.

Join host Jeff Corwin on a conservation adventure, beginning in California's Big Sur to help save the majestic California condor. At the Ventana Wildlife Society, Corwin assists in preparing juvenile condors for release into the wild. This iconic bird, North America's largest, was rescued from a population of just 22 individuals in 1982 through a dedicated captive breeding program. Today, approximately 500 condors exist worldwide, with about 300 flying free across the American West and Mexico.

Corwin then travels to his home state of Massachusetts to work with the Department of Fish and Wildlife. His mission there is to protect the unique saltmarsh sparrow, a species vital to the delicate salt marsh habitats of the East Coast.

Join Jeff Corwin as he investigates critical mammal conservation challenges. He reveals that nearly a quarter of all mammals face extinction, with wild species comprising only 4% of global mammal biomass. Corwin focuses on New England's orphaned black bear cubs, increasingly threatened by habitat loss and human proximity.

At the Kilham Bear Center, caregivers like Ethan Kilham raise these cubs, mimicking a mother bear to ensure they remain wild. The aim is to prepare them for release at 18 months, minimizing human interaction. The program showcases the careful process of sedating, health-checking, and tagging cubs like Flower and Dover before their successful return to the wild.

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 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.
