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.

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 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 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.

Host Jeff Corwin travels to Alaska's Cook Inlet to assist conservationists Nicole Whittington-Evans and Suzanne Steinert in monitoring the critically endangered beluga whale population. These "great white canaries of the sea" are uniquely adapted to Arctic life, using echolocation and feeding on salmon, but their numbers have drastically declined.

The Cook Inlet beluga population has plummeted by nearly 80% since the late 1980s due to habitat degradation, climate change, and other cumulative human impacts. Conservation efforts focus on reducing these threats and balancing human and wildlife needs to ensure these iconic whales survive for future generations.
