Not that long ago the plains and forests of North America teemed with wildlife, including more than 30,000,000 plains bison and hundreds of thousands of their northern relative, the wood bison. By the late 1800s both were extirpated from their ancestral lands. This depopulation of a keystone species had significant implications for the other species that depended upon them for their very survival. This presentation takes the viewer from the time when prehistoric species roamed the continent, through to the present, and discusses modern threats to grassland insects and birds that depend on bison and healthy ecosystems today.
