Some facts about Groundhogs othewise known as Woodchucks.
Groundhog burrows are important shelter resources for red fox, gray fox, opossum, raccoon, and skunk, most of whom do not dig their own burrows, but simply occupy those of groundhogs.
Over the course of the last 300 years, as forests have fallen to farms, the population of woodchucks and mid-sized predators such as fox and raccoon, have skyrocketed.
All of these animals are classified as "edge" creatures that thrive on multiple food sources found where forests meet field and yard.
Today, there are more groundhogs, red fox, gray fox, opossum and raccoon in the United States than at any previous time in U.S. history.
