Chronic wasting disease management

CWD hunt scheduled in portions of Winona and Houston counties

A special hunt to help limit the spread of chronic wasting disease in wild deer is scheduled later this month in deer permit area 346.

Test results from the recently concluded special CWD hunt in the disease management zone, deer permit area 603, are available on the test results page.

Test results

  • Is your test in? Type in your DNR number and check for results.
  • All deer that test positive for CWD will be reported on the results page. DNR will directly notify any hunter who harvests a deer that tests positive.

Share the harvest

Hunters can donate deer and people can sign up to receive donated venison through a harvest sharing partnership in southeast Minnesota with the Blufflands Whitetails Association. To participate, hunters simply need to bring their field-dressed deer to the Preston Forestry office. People who would like to receive donated venison can add their name to the first-come, first-served donation list.


Current deer feeding and attractants bans

The deer feeding and attractants ban has expanded and now includes Wabasha County. For definitions of feed, attractants and where the bans are currently in place, visit the feeding and attractant bans page for more information.

Southeast deer movement study

During March 2018, DNR used a helicopter company to live-capture deer in southeast Minnesota. These deer were equipped with GPS collars to track movements, particularly those of juvenile deer leaving their natal home ranges. This information will help us understand movements and potential spread of CWD in this area.

Collared and ear-tagged deer are not protected and any hunter may harvest them during a hunting season. If you do harvest a collared or ear-tagged deer, please notify DNR by calling 507-380-1858. If you capture any pictures of a collared deer and are willing to share, please email them to [email protected].
