All 52 of New Hampshire’s American ermine records are iNaturalist observations, a modest count for such a small, secretive weasel. Grafton County leads with 15 and Hillsborough follows with 12, and a couple each come from White Mountain National Forest and the Appalachian Trail. NatureServe hasn’t assigned it a state rank here, and New Hampshire doesn’t list it under its own conservation framework.
Records appear in every month, peaking in July with a second rise in October and November and dipping to a single record in February. Because every record is a photo, that calendar says as much about when people happen to cross paths with an ermine as about what the animal itself is doing.
