Tom Opre talks conservation; wildlife deserts; wolves; the fall of communism; ecosystem collapse, grizzly bears; Spanish conquistadors; and the human population collapse with world renowned wildlife biologist Dr. Valerius Geist.  Oh, they also get into big issues facing the Mule Deer, including chronic wasting disease (CWD).  Geist is a Canadian biologist and a professor emeritus in the Faculty of Environmental Design at the University of Calgary. He is a specialist on the biology, behavior, and social dynamics of North American large mammals (elk, moose, bighorn sheep, other wild ungulates and wolves).
