New Hampshire holds just 51 marten records, and 29 of them, more than half the state’s total, come from a single place: White Mountain National Forest.
A forest specialist pushed into the high country
An American marten needs mature conifer or mixed forest with a thick, unbroken canopy and plenty of standing dead wood and downed logs for den sites, cover it avoids leaving even to cross open ground. Heavy logging and trapping pushed the species out of most of New Hampshire by the early 1900s, and the high-elevation spruce-fir forest of the White Mountains and the country near Umbagog National Wildlife Refuge in the North Country are where the mature, complex forest it needs has held on longest.
A thin, scattered record of a scarce animal
Reports trickle in through the year at a low, steady rate, with a small rise in late spring. With only 51 records across the whole state, that pattern says more about how hard the species is to detect than about its true numbers. Martens are small, largely active at night, and stay under forest cover rather than crossing anything open.
Status in New Hampshire
The American marten is native to New Hampshire, but NatureServe ranks it S2, imperiled, the rarest status of any species in this batch. Its recovery depends on the mature, unbroken forest still standing in the White Mountains and the North Country.
