Researchers have studied the predator–prey dynamics on Isle Royale since 1958, making the project the longest-running of its kind. The Lake Superior archipelago was declared a U.S. National Park in 1940, and this designation saved the remaining wilderness from further logging and mining. The dwindling animal populations rebounded as human industry receded, and the periodic fluctuation of wolf and moose numbers began anew, continuing to this day.
The Isle Royale Wolf/Moose Study celebrates its 50th anniversary in late July. Groups such as the National Park Service and the Earthwatch Institute, among others, help fund the research led by the Michigan Tech faculty.
