Groundhogs

Habits

Groundhogs are known to burrow in fields and pastures, along fences and roadsides, and near building foundations or the bases of trees, leaving mounds of soil at the dig site. Groundhogs are primarily active during daylight hours, usually feeding in the early morning. They are strict herbivores and eat a variety of vegetables including soybeans, beans, peas, carrot tops, alfalfa and grasses. When not feeding, they are known to sunbathe during the warmest periods of the day.

Groundhogs are among the few mammals that enter into true hibernation, which generally starts in late fall near the end of October and continues until late February. Every year on February 2, people around the country celebrate Groundhog Day, a tradition that centers around the idea of a groundhog emerging from its hibernation to "predict" the weather. If the groundhog sees its shadow and returns to its burrow, there will be six more weeks of winter. But, if the animal does not see its shadow, then spring is right around the corner. The Groundhog Day ceremony featuring Punxsutawney Phil in Pennsylvania is the most popular.

Habitat

The most commonly-known woodchuck species, the Marmota monax or groundhog, mainly lives in the eastern part of North America but also extends into the Northwest. The other five species, however, are all located in the West, and have the common name “marmot.” Groundhogs are generally found in open and closed forests and bushy areas. In agricultural areas, they live along creeks, pastures and wooded areas where they can create extensive burrow systems.

Threats

Groundhogs are considered a nuisance pest because they can cause extensive damage to home gardens, farms, orchards and field crops as a result of their feeding and burrowing habits. When burrowing, they have been known to destroy building foundations, create unwanted holes on lawns and cause electrical outages from gnawing on underground wires.

Groundhogs rarely come in contact with humans and therefore pose no major public health hazards. However, they are capable of carrying fleas, ticks and rabies.
