Groundhogs are recorded often in Massachusetts, with just over 2,000 occurrence records spread across the state. Few Massachusetts mammals are easier to spot in the open, sitting up in a field or along a roadside edge.
A field-and-edge animal found statewide
Groundhog records turn up from the Boston Basin’s suburban lawns and wooded reservations near Blue Hills Reservation to the coastal plain’s fields around Cape Cod National Seashore and the marshes bordering Parker River National Wildlife Refuge. Wherever Massachusetts still has open grass bordering woods or a stone wall, a groundhog will usually find a bank to dig a burrow into.
A true hibernator, not just a winter no-show
A groundhog is one of the few Massachusetts mammals that hibernates for real, its heart rate and body temperature dropping for months at a stretch rather than the light, on-and-off dormancy a chipmunk uses. It spends late summer and early fall fattening up on clover, grasses, and garden vegetables before sealing itself into a burrow chamber sometime in October or November.
Records nearly vanish in winter, and that’s real
Reports fall to almost nothing from November through February, and unlike most seasonal dips in this kind of data, that drop is a fair reflection of biology rather than just people looking less. A hibernating groundhog isn’t out there to be missed. It genuinely isn’t moving.
Status in Massachusetts
NatureServe ranks the groundhog S5, secure, and it’s native to the state. Its burrows do double duty well beyond its own hibernation, since abandoned groundhog dens across Massachusetts fields and hedgerows become winter shelter for foxes, skunks, and other animals that never dig one of their own.
