While it is true woodchucks can be difficult to trap, this fact is primarily due to the laws in various states rather than any inherent intelligence on the part of the woodchuck . A stocky four legged ground animal.
Face is pudgy with a large nose and a black tail.
Has been known to climb trees up to 10 feet. Mating takes place in March. Open fields and broken forests with well drained soil. I have personally seen a woodchuck dig a hole under a concrete home slab so that it had a hole on both sides. While this digging is not a huge problem in terms of numbers, it can be a huge problem in terms of dollars.
