The population Biology of Sclerocarya birrea at Nylsvley Nature Reserve, Limpopo Province, South Africa
The overall aim of this study was to determine the population biology of Sclerocarya birrea (A Rich) Hochst., subspecies caffra (Sond) at Nylsvley Nature Reserve, Limpopo, South Africa. Sclerocarya birrea is a keystone plant species which is rated as one of the most highly valued indigenous trees because of its multiple uses. It is identified as a key species to support the livelihood of rural communities and it is central to various commercial activities. Sclerocarya birrea is also widely used by game in protected areas and by humans in communal areas for its fruit, wood and medicinal properties. Understanding the population biology for this key stone species is important as there are many environmental factors that are affecting its population structure. The study found that the population of S. birrea at Nylsvley Nature Reserve is fairly healthy and is mainly comprised of seedling and adult trees. Evidence of predators feeding on the seeds of Sclerocarya birrea was also recorded in this study. Additionally, disturbance, such as fire and cutting do not have negative impact on S.barrea
