2025 CWD Management Preference Survey |
CWD Management Actions
Chronic Wasting Disease (CWD) is a fatal neurological disease that affects several species of deer. First detected in Wisconsin in 2002, the geographic distribution of the disease in the wild deer population has increased. While CWD affects a greater proportion of the deer population in southwestern Wisconsin, the number of deer affected by this disease can vary widely both within a county and across the entire state. Results on how CWD affects Wisconsin’s deer population were recently released by the DNR.
