The ecology of the sable antelope Hippotragus niger niger (Harris 1838) in the Masebe Nature Reserve, Lebowa

Abstract

An investigation of certain aspects of sable ecology was undertaken attempt to assess the success of the relocation of the herd from the in an Potlake Nature Reserve to the Masebe Nature Reserve in Lebowa. The available habitat within the study area was classified into four distinct types. Analysis of observational and telemetric data indicated that the sable herd selected the plateaus above the other three habitat types, namely valleys, slopes and riverine vegetation. Home range of the herd was recorded and its size and position were related to water dependence. Results of faecal analysis of sable diet were compared to dietary items recorded in the literature and a significant increase in browsing during the dry period was noted. Behavioural\ investigations indicated typical hierarchical behaviour for sable antelope despite the small herd size of nine individuals. Management recommendations based on the findings of this study and on general theoretical conservation principles are proposed. It is suggested that sable distribution may be related to avoidance of competition from other grazers such as impala, or to predator avoidance. Theoretical implications of relocation are discussed with particular reference to genetic conservation.
