MADISON, Wis. (WSAU) -- Wildlife officials are calculating the winter toll on the deer herd with radio collars and road kill information.
The DNR wildlife biologists use ten road kill carcasses from every county. Those 720 dead deer are examined to see how much fat their bodies stored, and if the deer were pregnant.
DNR researchers say the winter was harsh on the herd, as nearly 30 percent of collared fawns in the northwoods died this winter, and another 15 percent of fawns in the farmlands died. Adult deer fared better. The leading causes of winter deer deaths were predation, car crashes, and starvation.
The data collected will give biologists a better understanding of how healthy the herd is, and how many deer are out there.
