Michigan Wolf Population Estimated With Remote Cameras for First Time
For the first time, researchers from Michigan State University, in collaboration with the Michigan Department of Natural Resources (DNR), have assessed the wolf population in Michigan through remote cameras. Launched in 2022, the initiative involved the installation of 1,311 cameras throughout the Upper Peninsula, generating over two million images analyzed by machine-learning technology. Monthly population estimates fluctuated between 525 wolves in March 2025 and 1,198 in October 2024, aligning closely with the DNR's winter track survey, which recorded nearly 800 wolves in February and March 2024. This camera survey offers continuous insights into population dynamics. Tyler Petroelje and project researcher Jerrold Belant highlighted its potential for monitoring various species, with the DNR also examining gray foxes using similar methods.
