At least four moose have died in a deep mud pit on Isle Royale, according to researchers. The mud pit is the result of a broken beaver dam and a draining lake. There are currently about 1,600 moose on the island, researchers have said, and some are concerned with the possibility of overpopulation. Following an effort to trap wolves in other areas and release them on the island, a dozen wolves are now living on Isle Royale and evidence of moose killed by the wolves has been located by the researchers. These moose, though, succumbed to a different fate. MORE ►Extra ribs, crooked backs show inbreeding that caused Isle Royale's old wolf packs to crash |
