Damage. Ground squirrels normally do not cause extensive damage in urban areas. However, they will feed on flowers and vegetables in gardens, and their burrows can be a nuisance. In rural areas, ground squirrels can do extensive damage to cropland or pastures.
Ground squirrels dig holes, of course, and they are easy to spot, as are gopher holes and mole holes, with the dirt piled around the entrances. Moles tend to have their entrances in the center of the excavated dirt, so it looks like a volcano, while gopher holes are eccentric.
