What to do if you see a sick or dead deer

Please notify the DNR if you see a sick or dead deer or multiple dead deer in any one area. Reporting is the most efficient way to monitor disease and remove disease agents.


Contact your local county biologist during business hours. The DNR call center staff are also available every day from 7 a.m. to 10 p.m. at 1-888-WDNRINFO (1-888-936-7463). Individuals in southern Wisconsin can also contact deer biologist Eric Canania, who can be reached by phone at 608-341-9615, or by email.
