New Hampshire’s record for the white-tailed deer is the largest of any mammal in this atlas, 4,848 records reaching all ten counties. The heaviest counts come from Sullivan, Hillsborough, and Grafton counties, but the species turns up from Rockingham County on the Seacoast to Coos County in the far north, in farm country, suburbs, and deep woods alike.
An edge animal in a forested state
White-tailed deer live on browse, twigs, buds, acorns, and tender new growth, so they do best where forest meets open ground. New Hampshire’s patchwork of fields, regenerating cuts, and second-growth woodland suits them perfectly. White Mountain National Forest and Umbagog National Wildlife Refuge hold deer around their openings and lower slopes rather than on the highest, most exposed terrain, and records at places like Grafton Pond and McDaniels Marsh Wildlife Management Area sit exactly where wetland edges and young cover meet.
A calendar that never fully quiets
Sightings run in every month, rising sharply through May and June when fawning season and fresh green growth draw deer into the open. Counts stay strong into the autumn rut in October and November, then thin through winter as deer yard up in dense conifer cover, a classic northern habit that lets them conserve energy and move more easily through deep snow.
Status in New Hampshire
NatureServe ranks the white-tailed deer S5, Secure, in New Hampshire, and the species is native to the state. Hunted nearly out of New Hampshire by the late 1800s, deer recovered as abandoned farms returned to young forest, and USGS NAS does not list the species as nonindigenous here.
