Long-term Change in Vegetation and Moose Browsing on Isle Royale National Park

Emeritus professor Peter Jordan has been monitoring the interactions of moose and vegetation of Isle Royale on a set of plots that spans the island, for more than 40 years. The Center will continue this project, and now that moose populations have reached a multi-decade low, earthworms are invading the island, and temperatures in Lake Superior are rising, there should be many interesting changes to forests in the years ahead.
