Models of Bontebok (Damaliscus pygargus pygargus, Pallas 1766) habitat preferences in the Bontebok National Park and sustainable stocking rates

[摘要] ENGLISH ABSTRACT:This study concentrates on the Bontebok (Damaliscus pygargus pygargus Pallas 1766) populationof the Bontebok National Park. Using a combination of literature research, field observations,satellite imagery, Geographic Information System mapping and dung analysis, their habitatpreferences within the Park are ascertained and compared to different behavioural andenvironmental factors. Considering vegetation composition and height, grass cover, burning history,general topography, water availability, actual diet quality (from faecal analysis) and populationdistribution, the best predictor of spatial pattern are investigated with GIS Dempster-Shafer models.The historical density distribution of the animals in the Park can be used to predict sustainablestocking rates. As far as possible, the results for the Bontebok are compared to those of the otherlarger herbivores in Bontebok National Park i.e. Red Hartebeest, Cape Mountain Zebra and GreyRhebuck. These results should be useful for Wildlife Managers to know how to manage veld forBontebok and at what stocking rates this can be done sustainably.
