What does it take to track down one of the most elusive species in some of America’s harshest winter environments? How do you study an animal that is rarely heard or seen? For many years, wildlife biologists in Yellowstone National Park have been searching the backcountry for signs of wild cougars to understand their ecology for conservation planning. Colby Anton is a PhD student in Environmental Studies at UC Santa Cruz and a biologist with the Yellowstone Cougar Project. He will be taking you on a visual journey to Yellowstone National Park where scientists have been at the forefront of large carnivore conservation for decades. You will hear about how they study the Park’s cougar population as well as our motivations to learn more about large carnivore ecology in the country's first national park.
