Title:

More woody plants? the status of bush encroachment in Botswana's grazing areas

Publication Year:
2002
Abstract:

Foci points, which are currently intensified by increased anthropogenic activities, have resulted in vegetation changes in the cattle-dominated grazing areas of Botswana. Bush encroachment species - for instance Acacia tortilis, A. erubescens, A. mellifera, Dichrostachys cinerea, Grewia flava, and Terminalia sericea - are increasing in cover and density around foci points (e.g. water points and kraals) at the expense of the grass cover. A number of factors have the effect of encouraging the germination and survival of bush encroachment species. The practice of cattle husbandry and continual shifting of foci points within grazing areas have resulted in the spread of the distribution of bush encroachment species across the country. Keywords: Botswana, bush encroachment, foci points, management options.
