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
gestation period is about four weeks and the average litter size is two. Despite this low level of fecundity, the southeastern pocket gopher is a common animal, implying that there is good survivability of the offspring. The presence of green forage in the diet and the fact that
owls sometimes feed on them show that the gophers do emerge above ground sometimes. However, predators underground are few, the chief dangers being
snakes and
weasels. A number of
arthropods share the burrows with the gophers, including about fourteen species that are found nowhere else. The gophers are attracted to cultivated land, particularly
sweet potato crops, and can also be a
pest in
peanut and
pea crops, and
sugarcane plantations. ==References==
