Wolf Harassment Has Little Impact On Elk

Middleton et al

Deer survival is influenced by many factors including disease, predation, weather, and hunter harvest.

In the Upper Peninsula (UP), deer survival is especially influenced by winter food supply and cover. Research is needed to better understand the impact of predation on deer, while also determining how predation is influenced by winter weather and deer habitat conditions.
