WOLF ISLAND

A naturalist’s memoir of seasons spent over many decades studying the ways of wolves.

No one knows more about wolves than Mech, a Minnesota-based researcher for the U.S. Geological Survey. As he writes in this engaging narrative, he started off working with bears, but, “while I was interested in weasels and mink, their wilderness relative the fisher fascinated me even more. Among the dog family, I was fond of working with foxes, but I much preferred snowshoeing through the Adirondack Mountains in search of their larger, wilder cousin, the coyote, or brush wolf.” An almost-chance encounter with a scholar who would become a mentor took him to Purdue University for graduate study, and there he was posted to Isle Royale National Park, a remote outpost in Lake Superior closer to Canada than the U.S. Moose had swum to the island long before, and in pursuit came a small squad of wolves. “It had no roads, so visitors arrived by boat and traveled on foot on its trails, or by water along the shoreline,” writes Mech. “No one lived there for most of the year.” That was just fine by him. In time, a wife and child joined him, but the author had much of the island to himself, commanding great views from a granite ridgeline on one hand and getting down to ground level to study wolf scat on the other. It was wild country with no end of danger, but “I learned that patience was the most important ingredient of safety.” Apart from a few odd interludes, including nearly becoming a John Bircher, he kept his eye on wolf-moose interactions and the fluctuating populations of both species. Given that he started at Isle Royale in 1958, his project “is the longest continuous study of any predator-prey system in the world,” a model for other studies that still raises fresh questions with every season.

Fans of wolves, field biology, and good natural history writing will welcome Mech’s long-overdue reminiscences.
