Isle Royale – Lake Superior’s island National Park – is a naturalist's playground. It’s home to an estimated 30 odd wolves and nearly 1000 moose – all protected from hunting. For decades now, a team of researchers have been surveying the wolf and moose populations, but this winter with record breaking warm weather, the census did not go as planned.
