The impact of giraffe, rhino and elephant on the habitat of a black rhino sanctuary in Kenya
The habitat in an enclosed black rhino sanctuary, the Sweetwaters Game Reserve in Kenya, is being altered as populations of elephant, giraffee and black rhino increase. Height-specific browse impact data were recorded for 1075 trees of the dominant species, the whistling thorn, Acacia drepanolobium. Rhinos and elephants browsed 18% of these trees in 1 year, […]
The ecology of the desert-dwelling elephants, black rhinoceroses and giraffe of western Kaokoland and Damaraland, South-West Africa
In the western desert regions of Kaokoland and Damaraland in S.W.A. elephants, black rhinoceroses and giraffes survive under environmental conditions atypical elsewhere for them. These animals occupy a seemingly inhospitable desert habitat, are locally endangered and occur in small numbers. The first priority of this study is directed at the acquisition of the relevant data […]
Population Constraints Associated with the Use of Black Rhinos as an Umbrella Species for Desert Herbivores
The numerous tactics used to conserve biodiversity include the designation of protected areas, political change, and research and education, the latter involving paradigms such as insular biogeography and the “umbrella species concept.” In Namibia lands removed from national park status in 1970 and currently under the jurisdiction of indigenous people now contain one of the […]
Effect of low rainfall and browsing by large herbivores on an enclosed savannah habitat in Kenya
Savannah ecosystems in East Africa are rarely stable and can experience rapid local changes from dense woodlands to open plains. In this 3-year study there was a reduction of 16.3% in a height-stratified sample of nearly 1000 individually marked Acacia drepanolobium trees. The study was carried out in an enclosed fire-free wooded grassland habitat in […]
