March 20 – The moose of Isle Royale and Yellowstone National Parks – Ky Koitzsch
Join wildlife biologist Ky Koitzsch as he shares his experiences skiing in the backcountry wilds of Yellowstone and Isle Royale National Parks with his field partner and wife Lisa to study North America’s most magnificent deer, the moose. In Yellowstone, as an alternative to traditional aerial surveys, the couple implemented cutting-edge, non-invasive genetic and hormonal methods to accurately assess population parameters. On Isle Royale, where researchers have been studying moose and wolves for over 60 years, and where wolves are currently being reintroduced to suppress the growing moose population, Ky and Lisa apply similar non-invasive methods to study how chemical defenses in the moose’s winter browse, balsam fir, affects its mid-winter nutritional condition. Ky will also discuss why moose are in decline across the southern reaches of their North American distribution, including here in New England.
