New Hampshire’s 15 records make the southern bog lemming one of the more quietly documented mammals in the state. Ten of the 15 come from Strafford County in the southeast, with Coos County in the far north adding 3 and Grafton 1. Records bunched that tightly usually reflect one local survey effort, not a population center, so the state’s real distribution is almost certainly wider than the map shows.
A late-summer lean
The dated reports spread across six months of the year, leaning toward August and September with 3 records each and a smaller rise in November and March. With a sample this small, no month claims a true pattern, but the spread itself is informative: it fits an animal that never hibernates and keeps working its runways beneath the grass in every season, winter included.
Where the right ground is
The Lakes Region’s marshy margins, the boggy shoreline of Umbagog National Wildlife Refuge, and the wet meadows around Great Bay all hold the thick, moist sedge cover this species depends on, and the Strafford County cluster sits in the same corner of the state as Great Bay. NatureServe ranks the species S4 in New Hampshire, apparently secure, so the thin record most likely reflects how rarely anyone traps for a hidden runway-builder, not genuine scarcity.
