North Dakota’s groundhog record is thin, just 29 occurrence points, but that fits an animal that spends nearly half the year underground and asleep. Most of what’s on record clusters in the warm months, when a groundhog is actually up and moving.
Burrows at the edge of tree and grass
Groundhogs need well-drained soil to dig a burrow system and prefer the seam between open ground and woody cover, a habitat that’s scattered in a state this dominated by grassland and cropland. Records track those edges: the grassy rims above the Little Missouri Badlands around Theodore Roosevelt National Park, the bluffs and wooded draws along Lake Sakakawea, and the field margins bordering the wetlands at J. Clark Salyer National Wildlife Refuge out in the Drift Prairie. Open, treeless prairie between those pockets offers little for a burrowing animal that still wants some cover nearby.
A true hibernator, and the record shows it
No records appear from November through February. Unlike a chipmunk or a ground squirrel that wakes periodically to feed, a groundhog drops its body temperature and heart rate for a genuine winter-long sleep underground, only emerging once the ground has thawed enough to dig and graze again. The record’s spring-to-fall shape isn’t a gap in reporting; it lines up with when the animal is actually active.
Status in North Dakota
The groundhog’s North Dakota NatureServe rank is SNR, unranked, though it’s secure globally at G5. It’s native to its North Dakota range, holding on in the patchy edge habitat this mostly-eastern woodchuck can find on the prairie.
