从1978年12月至1979年11月，肯尼亚牧场生态监测组(KREMU)对纳鲁克南部牧场上的大型食草动物进行了每月计数。当时，这些牧场养活了每年132只/平方公里的食草动物种群，相当于160公斤/公顷的生物量。马拉平原，特别是被保护为马赛-马拉国家保护区的地区，是关键的旱季范围。在旱季高峰期(7月)，来自塞伦盖蒂的大型迁徙牛群补充了100,000头蓝角马的常驻种群，使总数量增加到800,000英镑。伯切尔斑马(Equus Burchelli)和汤姆森瞪羚(Gazella Thomsoni)迁徙较少，但通过Mara、Siana和Loita范围单位进行季节性迁移。
Monthly counts of large herbivores on the rangelands of southern Narok District were conducted by the Kenya Rangeland Ecological Monitoring Unit (KREMU) from December 1978 to November 1979. At that time these rangelands supported year-long herbivore populations of 132/km2 representing a biomass of 160 kg/ha. The Mara Plains, particularly the area protected as the Masai-Mara National Reserve, served as a critical dry season range. During the peak of the dry season (Jul), the resident population of 100,000 blue wildebeest (Connochaetes taurinus) was supplemented with large migratory herds from the Serengeti which increased total numbers to >800,000. Burchell's zebras (Equus burchelli) and Thomson's gazelles (Gazella thomsoni) were less migratory but moved seasonally through the Mara, Siana, and Loita range units.
