Gopher tunnel networks can be up to 9 feet in depth. If their tunnels are neglected for long periods the under ground will look like Swiss cheese. Often surrounding yards have gophers which affect adjacent properties and usually the tunnels between the two areas connect. Since the tunnels are so deep they cannot be destroyed, therefore there is always a route for gophers to follow.
Gophers do not hibernate so they are active all year long. They also have the ability to be active at all hours of the day. Gophers usually live alone within their burrow system, except for females with young or when they are breeding.Breeding season usally starts late winter to early spring. Gophers will breed 1 to 2 times a year with 3 to 7 pups per litter. Gophers live up to 3 years and they can start breeding at 1 yearof age.
