The complete county distribution, spread across 7 Maine counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Maine is wolf country on paper only. Gray wolves were wiped out of the state by the early twentieth century, and NatureServe now ranks the species as possibly extirpated there. There is no resident pack to find, and the 15 records in the modern occurrence databases don’t describe a living Maine population. They’re a mix of older material and the occasional wide-ranging animal that drifted in and didn’t stay.

The scatter of those records is itself informative. Hancock County on the coast holds five, while Penobscot, Aroostook, Piscataquis, and a few others hold one or two apiece, with no single place standing out. Reports land in every season with no pattern, which is what you’d expect from historical specimens and rare wanderers rather than a breeding population with a seasonal rhythm.

Maine’s northern woods, especially along the Quebec border, remain the most plausible corridor for a disperser crossing in from Canada, and big-canid sightings in the state reliably stir debate. But a sighting isn’t a population. For now the gray wolf belongs to Maine’s past, and any verified return would be news, not a trend these records reveal.
