Figure 5.10: Map of Botswana showing how the country is now divided into two distinct systems I GHANZdDISTRICT I Source: Crowe, 1995. Movement of wildlife as noted by Ross (1987) is restricted between the two and within the systems. Within the Southwestern System, wildlife movements are inhibited by the Kuke veterinary fence and the eastern boundary of the Central Kalahari Game Reserve. Human settlements and livestock also add to the increasing pressure placed on the wildlife, especially in the Kweneng District. The Northeastern System restricts animal movement to and from the Okavango Delta via the Buffalo fence. According to Owens and Owens (1985), the restrictions that the veterinary cordon fences have caused have led to devastating effects on the wildlife populations of Botswana. Ross (1987) shows that in times of drought, when the rains have failed 212
for several consecutive years, the devastation that the fences and the increasing livestock population has on the wildlife can be seen on the largest scale. Wildebeest are often the most seriously affected species in the Southwestern System since they are completely dependent on water. The largest concentration of wildebeest during the wet season is along the boundary between the Ghanzi and Kgalagadi districts. However, their migration to the permanent water of the Okavango Delta in the dry season is restricted due to the Kuke Fence (Crowe, 1995). This restriction has caused a vast reduction in the wildebeest population. As Ross (1987) shows, the drought years of the 1980s had a huge effect on the wildebeest population, where approximately 52 000 of the 80 000 wildebeest that migrated died. Eland and hartebeest populations have also been greatly affected by the construction of the veterinary cordon fences. The hartebeest in the Southwestern System historically migrated in a north-easterly direction from the Kgalagadi and Ghanzi districts. This movement however, is now restricted due to the construction of fences and an increasing amount of human settlements in the area. Hartebeest numbers have therefore declined dramatically in the last 15 years, resulting in a loss of 83% of the population. As shown in Figure 5.11, the combined seasonal distribution of wildebeest, hartebeest and eland requires a vast area to sustain these populations over the long term. It is obvious that this movement can not be accomplished due to an increasing human population in Botswana (Crowe, 1995). Taolo (1997) notes that a comparison of the distribution of the biomass of wild species with that of domestic livestock suggests that the two seem to be mutually exclusive and thus wildlife numbers will only increase in areas where the livestock biomass has decreased. It is likely that with continued livestock expansion, wildlife will be displaced. This creates an inverse relationship between the wildlife and livestock populations, a relationship which is a reflection of human distribution and a result of the disturbance to the wildlife migration patterns to which this distribution has contributed. 213
