Above-average snowfall in late winter and spring is expected to take a toll on the Upper Peninsula's deer.
The Michigan Department of Natural Resources says mild winters such as the region experienced from 2010 to 2012 are good for deer, improving their survival rates and helping pregnant does give birth to healthy fawns.
But harsh winters with deep snows limit deer movement and burn up their energy reserves.
This year, the U.P. experienced heavy snow in February, March and well into April. DNR biologists say the region's deer are looking thin and lethargic. Some reports of deaths are coming in.
The DNR says it's too early to say how seriously the deer population has been affected. But they say if nothing else, its growth rate is likely to slow down.
