Wolverines conjure images of fierce, almost mythical creatures roaming frozen tundra, yet their actual presence in the modern United States often sparks confusion.
Are Wolverines Native to Michigan's Lower Peninsula: A Complete Extirpation
These are not breeding residents but wanderers following their instinct to explore new territories. By the early 20th century, the combination of these factors led to the complete extirpation of wolverines from the Lower Peninsula and a significant reduction in the Upper Peninsula population.
For the animal to re-establish itself as a native component of the ecosystem, a sustained breeding population would need to take hold, which remains a distant prospect dependent on habitat connectivity and climate stability. 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.
