New Jersey’s occurrence records for the American mink sit at 233, all from iNaturalist observations. A mink is built to disappear along a shoreline, so even a healthy population leaves a thin paper trail.

Salt marsh edges and Pine Barrens streams

Mink never stray far from water, and New Jersey supplies several kinds of shoreline for one to patrol. Records cluster around the wetland mosaic of Great Swamp National Wildlife Refuge in the Piedmont, the tidal salt marsh and back bays at Edwin B. Forsythe National Wildlife Refuge along the Atlantic coast, and the blackwater streams threading Brendan T. Byrne State Forest in the Pine Barrens. Coastal tide pools count as habitat just as much as a freshwater creek does, which is part of why the species turns up in such different corners of the state.

A hunter that works both banks

A mink takes fish, crayfish, and frogs in the water, then turns to voles, muskrats, and ground-nesting birds on land, switching between the two as seasons change. That flexibility, plus a low, webbed-toe build suited to swimming well below the surface, is what lets a solitary mink cover a mile or more of bank without needing open fields or deep woods at all.
