Wolves have decimated the moose population in Minnesota. Recent official numbers prove that the wolf is largely responsible for the dramatic decline in the moose population of NE Minnesota.

Results from repeated studies in MN fly in the face of those trying to blame global warming for the precipitous drop in moose numbers in order to ban wolf hunting. Certainly disease plays a part, but a proven 50% to 80% moose calf mortality from wolf predation doesn't help matters any.

There are a record number of wolves (2,200+) and each eats 10 pounds of meat a day. They will eat dogs, cats, rabbits etc, but those are small and scarce in wolf country. They also go after livestock when they can, but farmers are permitted to control them in some circumstances or get reimbursement. Their primary prey is the whitetail deer and since there is probably 40 to 50 pounds of edible meat on an average whitetail, simple math reveals the carnage they inflict on the whitetail population and moose calves.

Add to that the statewide scourge of coyotes and coy-wolves, and not much with fur or feathers is spared.
