Herbivores on the Serengeti Plain
Herbivores (plant- eating animals) living in the same environment often compete for food plants. But in some cases, herbivores may cooperate in the harvesting of plant matter. The grazing system of large herbivores on the Serengeti Plain of east Africa is an excellent illustration of how these animals may interact over their food supply. The Serengeti Plain contains the most spectacular concentration of large mammals found anywhere in the world. Approximately 1,000,000 wildebeests, 600,000 Thomson’s gazelles, 200,000 zebras, and 65,000 buffalo occupy an area of 23,000 square kilometers (9,000 square miles), along with undetermined numbers of 20 other species of grazing animals.
