Habitat

The groundhog dwells in lowland habitats, unlike other marmots that live in rocky and mountainous areas. Marmota monax has a wide geographic range. The groundhog prefers open country and the edges of woodland, being rarely found far from a burrow entrance. It can typically be found in small woodlots, low-elevation forests, fields and pastures, and hedgerows. It constructs dens in well-drained soil, and most groundhogs have summer and winter dens. Human activity has increased food access and abundance, allowing M. monax to thrive.

Map

map of groundhog habitat

This map shows groundhogs inhabiting the eastern and central parts of the United States, which are areas that have a lot of open fields, pastures, and woodlands.
These areas also let groundhogs take advantage of human activity, as the land higlighted by the map are areas of agriculture, giving a source of food to groundhogs.
