The low numbers make the population vulnerable to inbreeding depression and reduce their long-term viability without natural migration from healthier Canadian sources. Habitat loss and fragmentation from logging and agricultural expansion reduced the old-growth forest cover essential for denning and hunting.

Furthermore, unregulated trapping and predator control programs aimed at protecting livestock decimated their numbers. Wildlife authorities rely on concrete evidence to track species presence, and the documentation of wolverines in Michigan is sparse but verifiable.
The animals currently present in the state are almost certainly transient individuals dispersing from larger populations in Canada or Wisconsin. This genetic differentiation suggests that the historical populations were separated and that the current individuals in Michigan represent a relict or recolonizing group with limited gene flow.

They inhabited vast stretches of the boreal forest and mountainous regions, including areas well south of the Canadian border. Scientific analysis provides further insight into the genetic isolation of Great Lakes wolverine populations.
