Ecology

''G. pinetis'' is a solitary animal and creates shallow tunnels above which are a series of mounds of excavated material. The soil is pushed upwards by the front limbs and chest and creates a fan-shaped mound with the tunnel at one side. The burrow entrance is immediately blocked with soil. These shallow tunnels are connected to a deeper tunnel system by a spiral "staircase". Down below are the food chambers and a nest chamber which may contain dried vegetation and plant fibres. Breeding takes place in spring and summer, peaking around February/March and June/July. The

s. The southeastern pocket gopher is active throughout the year. It feeds on roots and rhizomes below ground, and on green plants such as grasses, sedges and weeds which it can reach from near the entrance to the burrow. Large quantities of vegetation are gathered and carried back to store chambers in the burrow. Because its burrows promote plant growth, a case can be made that they are farmers. A number of
