Where is deadly EHD affecting deer in Michigan? New map shows reports

Key Points:

• The Michigan Department of Natural Resources (DNR) has released a new, regularly updated map showing township-level locations of deer suspected to have died from epizootic hemorrhagic disease (EHD) to address hunter concerns about deer losses.
• In 2026, EHD has been confirmed in deer from 15 counties, including Allegan, Branch, Clinton, and Oakland, with the disease spread by biting midges and typically occurring in late summer and early fall.
• The map reflects voluntary reports and confirmed cases through lab testing, but not all suspected cases can be confirmed due to testing constraints, so the map indicates reported activity rather than a complete count.
• DNR officials emphasize that while EHD can cause high mortality in localized areas, not all deer contract or die from the disease, and recovery of deer populations varies by location, as seen in past outbreaks.
• Hunters are encouraged to report suspected EHD cases via the DNR’s Eyes in the Field portal to assist wildlife staff in monitoring and managing the disease, with current confirmed cases similar in number to recent years.
