Author Roger L Di Silvestro is a professional conservationist, a former editor and writer for the National Audubon Society, and also worked for Defenders of Wildlife and the Oklahoma Department of Wildlife Conservation. In this episode of Nature Revisited, Roger discusses the topic of his latest book Return of the Bison, which tells the story of how this symbol of the American West was once almost lost to history and of the continuing journey to bring the bison back from the brink. Weaving in natural history and interesting historical contexts, along with the key role of America’s Indigenous people, Roger describes the complex history of the bison’s decimation and how a rising awareness of their possible extinction formed the roots of many modern wildlife conservation approaches.
