Groundhog Facts
Groundhog, also known as marmot or woodchuck, is the largest member of the squirrel family. It can be found in the northeastern and central parts of North America. Groundhog inhabits edges of the forest, fields and areas near the roads and human settlements. They are treated like pests in some areas because they feed on the crops and destroy land with underground tunnels. Groundhogs are often on a target of recreational hunters.
