During the 2020 hunting season, hunters may spot deer equipped with radio collars. Collared deer are part of a mortality study in the Wisconsin Department of Natural Resources and are legal to hunt with a standard Wisconsin hunting license and harvest authorization.
The DNR Office of Applied Science is conducting a long-term mortality study called the Southwest Wisconsin Chronic Wasting Disease, Deer and Predator Study. Researchers are investigating factors like CWD, predation and hunter harvest, and what degree these affect survivorship in deer. The project crew has put GPS collars on almost 850 deer across the southwest region of the state.
"One of our study objectives is to determine what proportion of our deer herd is harvested each year, and how exactly that differs according to how old the deer is, between bucks and does and between deer that are CWD-infected and those that are not," said Daniel Storm, a deer research scientist. "That objective depends on hunters essentially treating collared deer like any other deer when deciding whether or not to harvest."
Deer that are collared as part of the Southwest Wisconsin CWD, Deer and Predator study are legal to harvest. Standard licensing and harvest regulations apply to collared deer, just as they do to uncollared deer.
Hunters who harvest a collared deer are asked to call the (608)935-1940, the number on the collar so a crew member can retrieve it.
The DNR recommends testing for CWD for both collared and uncollared deer. The Department needs to test as many deer as possible for the disease to better understand CWD in Wisconsin.
