Defenders of the Wild

Ivan Carter and his team work to translocate 100 elephants from overpopulated areas facing degradation. The goal of the ambitious project? To repopulate some of Africa's most depleted national parks.

Dr. Dave Gaynor conducts a natural experiment and introduces lions and cheetahs into the Zambezi Delta to look at the role apex predators play, prey and adapt in the ecosystem.

Ivan Carter heads to the United States to investigate how hunters' dollars fund sheep conservation across the country. Follow along through a hands-on translocation that will re-establish a historic home range for the species.

Anti-poaching laws, community meat drops and upliftment initiatives are returning wildlife to the Zambezi Delta.

Once upon a time, there were millions of bison; now, there are less than 1,000. Ivan dives into the history of bison populations in the U.S., as well as the current state of their protection, and gets involved in collaring efforts in the Henry Mountains.
