Woody vegetation change in response to browsing in Ithala Game Reserve, South Africa
The impact of elephant and other browsers may be magnified when they are restricted within small, fenced reserves. These reserves are becoming commonplace in southern Africa. The composition and structure of the woody vegetation of a portion of the 30 000 ha Ithala Game Reserve, South Africa, was monitored annually from 1992 to 2000. Woody […]
Overlap and seasonal shifts in use of woody plant species amongst a guild of savanna browsers
To clarify the potential influence of different browsers in the same guild on woody vegetation, dietary overlap and separation between elephant, giraffe, kudu, nyala and impala was assessed in Hluhluwe-iMfolozi Park, South Africa. Woody species browsed, browsing heights, plant-parts browsed and browsing versus grazing were recorded over 2 y by direct observation. We obtained 3068 […]
Vegetation factors influencing density and distribution of wild large herbivores in a southern African savannah
Understanding factors influencing large herbivore densities and distribution in terrestrial ecosystems is a fundamental goal of ecology. This study examined environmental factors influencing the density and distribution of wild large herbivores in Gonarezhou National Park, Zimbabwe. Vegetation and surface water were predicted to have a stronger influence than anthropogenic-related disturbances (livestock grazing, fires, settlements and […]
Assessment of the woody vegetation of Ol Choro Oiroua, Masai Mara, Kenya
The woody vegetation of the Ol Choro Oiroua Wildlife Management and Conservation area was surveyed. The species present, their size and the vertical distribution of their canopy were recorded. These parameters were then used to determine the percentage cover of woody vegetation at different heights, and the potential productivity of the trees and shrubs in […]
