New research shows bear bait makes up more than 40 percent of a black bears diet in northern Wisconsin. Researchers say bait could be playing a role in the high density of bears up north. The region is home to around 20,400 bears.

Dave MacFarland, large carnivore specialist with the Wisconsin Department of Natural Resources, co-authored the findings published in the Journal of Wildlife Management last month.

"It was a study designed to better understand the ecology of bears in the state and the role that the various foods on the landscape play in the population," said MacFarland. "That gives us information on the impact of regulations. Its sort of a first step to better understanding the role of bait in bear diet."

Baits often consist of high-calorie foods like meat, candy or cookies.MacFarland, along with researchers at the University of Wisconsin-Madison,sampled bear bait and native foods in the Chequamegon-Nicolet National Forest for the study. They then compared those samples to tissues taken from black bears during the 2011-2013 hunting seasons.

The study was restricted to areas that were primarily forest and wetlands to minimize the influence of crop cover on results.

The Wisconsin DNR estimates around 4 million gallons of bear bait are used annually on the landscape, and researchers noted northern Wisconsin black bears had a higher percentage of bait in their diets than food-conditioned bears in Yosemite National Park.

Female black bears that eat bait have been known to experience increased fertility, but researchers say further study is needed to assess the impact of baiting policies on the bear population.

"Itd also be interesting to see what in states with different policies and different regulations what role bait is playing in the diet of those bears, said MacFarland. "Theres some more work potentially to be done, but I think its an important first step in us better understanding this.

The baiting period in Wisconsin is roughly three times longer than neighboring states Michigan and Minnesota. The state allows baiting from April 15 through early October.
