Some Life History and Ecological Activites of the Richardson Ground Squirrel In South Dakota

<p>Whenever man has gone he has changed his environment to suit his needs. Because of his need for food, man has plowed up the prairies and converted the grasslands to grain fields. Before white man settled the Great Plains, range rodents such as the prairie dog and the ground squirrel existed undisturbed and unmolested except by their natural predators. With the advent of cultivated crops, the range herbivores found a new and tasty source of food. Among these primary consumers which took advantage of man’s interference with the natural prairie was the Richardson ground squirrel, Citellus richardsoni (Figure 1). During the past few years, the Richardson ground squirrel has been found in increasing numbers in the central part of South Dakota. There has been very little investigation of this species of ground squirrel in the United States although some work has been done in Canada. The purpose of this study is (1) to determine the habits and activities in the life cycle of the Richardson ground squirrel; and (2) to compare these data with those indicated by other authors. Richardson ground squirrels do considerable damage to grain crops, soil, forage crops, and farm lands, and they are also a potential reservoir for bubonic plague.</p>
