"Pocket gophers, are burrowing rodents that get their name from the fur-lined, external cheek pouches, or pockets, they use for carrying food and nesting materials. They live in a burrow system that can cover an area that is 200 to 2,000 square feet. Feeding burrows usually are 6 to 12 inches below ground, and the nest and food storage chamber can be as deep as 6 feet. 
They feed on many garden crops, ornamental plants, vines, shrubs, and trees. A single gopher moving down a garden row can inflict considerable damage in a very short time. Gophers also gnaw and damage plastic water lines and lawn sprinkler systems. Their tunnels can divert and carry off irrigation water, which leads to soil erosion. Mounds on lawns interfere with mowing equipment and ruin the aesthetics of well-kept turfgrass." http://www.ipm.ucdavis.edu/PMG...
In Zuzu's garden last year.
Before, taken last year and after, taken a couple of days ago of my pretty
Betony (Betonica officinalis subsp. officinalis 'Hummelo')
This time one had a tunnel underneath but came to the surface to snatch all the stems. I thought a weed whacker got it.
