Wildebeest migration in the Kalahari



Between April 1981 and December 1984 aerial surveys were conducted in the northern Central Kalahari Game Reserve, the Lake Xau area and a larger area in southwestern Botswana. Range conditions were monitored in the northern Central Kalah, ri Game Reserve. The migration of wildebeest to surface water at Lake Xau was documented. Since the Kalahari wildebeest population has had severely restricted access to surface water for decades and this access is steadily diminishing, it is inferred that the existing population is smaller than it used to be and can be expected to decline further in the future.
