The other holes are typically within 15 feet of the main entrance and are less obvious. These provide alternative escape routes for a woodchuck caught off-guard topside. Except when rearing young, only one woodchuck occupies a burrow. Some burrows see more woodchuck activity than others, especially if they are found along above-ground woodchuck trails. These trails and accompanying burrows help woodchucks move from one habitat to another.
Home is where the garden is.
Woodchucks make their subterranean homes near their food source, which might be a vegetable garden. They are powerful tunnelers, with the ability to move more than 200 pounds of soil a year. Woodchucks leave signs of their activity. One of the ways woodchucks adapt to living near people is to adjust their patterns of activity around human interference. They may be active very early in the morning, late in evening, or during midday when most of us are at work.
