Sold out: Please sign up for the waitlist.
This course will explore trophic cascades, important direct and indirect interactions between species that can effect an ecosystem in significant, and possibly unexpected, ways. Investigating how wolf reintroduction, population fluctuations of elk and bison, and increasing populations of beavers interact, will show how much Yellowstone has changed.
Along the way, this course will investigate how these, and other species of plants and animals have been affected with field trips and short classroom discussions to emphasis important concepts.
