Also known as woodchucks, land-beavers, marmots, and whistle-pigs
(for the high-pitched whistle they emit when alarmed), groundhogs frequent areas where woodland meets open space such as fields, roads, and streams. In agricultural areas, they tend to live along creeks, pastures, and wooded spaces. Among the most conspicuous signs
that a groundhog might be shacking up on your property are 10 to 12-inch circular holes in the ground, especially if accompanied with a mound of dirt beside the dig-site. Other signs include large bites taken out of your crops and if the feathery tops of your carrots look like they have been mowed. Less obvious, though equally telling, are 1/4–3/4-inch teeth marks on wood, plantings, and lower branches of trees.
