A harsh winter in 1996-1997 was responsible for the death of thousands of elk, dramatically reducing the herd.

Greater Yellowstone Elk Suffer Worse Nutrition And Lower Birth Rates Due To Wolves

"Essentially, they are slowly starving," Creel said. "Despite grazing and browsing during the winter, elk suffer a net loss of weight. If winter continued, they would all die, because dormant plants provide limited protein and energy, and snow makes it more difficult to graze efficiently."

USFWS Wolf Chief Blames Moose Loss In Yellowstone On Climate Disruption : Black Bear Blog

Don Peay of Sportsmen for Fish and Wildlife in Utah asked Bangs:

I would like some scientist to explain to me how Utah – which has a hotter climate than Wyoming, Idaho and Montana whether there is global warming, climate disruption, etc – is seeing a totally different trend in Moose, than is being experienced in the wolf inhabited areas of WY, MT, and ID.

If Climate disruption is the reason that moose are declining in the Yellowstone region – it is so hot the moose populations just lie around and don’t put on fat reserves – then why are Utah moose populations increasing significantly during this same climate change phenomenon ? it would seem to me that if heat was the problem, then Utah’s moose populations should be even in greater decline than the greater Yellowstone area.
