The surroundings of Arctic Haven hold a spectacular concentration of wildlife: caribou, grizzly bears, arctic wolves, wolverines, golden eagles, bald eagles and more. Every Autumn (Fall), with the arrival of the northern lights, the Qamanirjuaq caribou herd leaves their summer calving grounds and journeys five hundred kilometres southward to their winter home. The Qamanirjuaq caribou number in the hundreds of thousands and are one of the healthiest herds in Canada. Several narrow sections of Ennadai Lake provide natural crossing places for the caribou. The Ennadai Lake area is also one of the most important locations in the arctic for migratory bird life.
