Analysing Shrub Encroachment in the Southern Kalahari: A Grid-Based Modelling Approach
TL;DR: The most significant finding of the simulation experiments was that, although the stocking rates currently recommended by pasture scientists are unlikely to lead to shrub encroachment within 20 years, they have a high probability of bringing about shrub intrusion within a century.

Vegetation of the Tembe Elephant Park, Maputaland, South Africa
TL;DR: A hierarchical classification, vegetation map, description and ecological interpretation of the plant communities of the Tembe Elephant Park and surrounding areas are presented in this article, where sixty-four sample plots were distributed in a stratified manner throughout the study area.

Mysterious circles in the Namib Desert: review of hypotheses on their origin
TL;DR: Circular, slightly concave depressions, devoid of vegetation and often surrounded by a fringe of tall grasses occur in a broken belt in the pro-Namib zone of the west coast of southern Africa, and no evidence of increased radioactivity could be detected in soil samples collected from these sites.

Vegetational gradients around artificial watering points in the Kalahari Gemsbok National Park
TL;DR: In this article, the authors investigated the relationship between vegetation composition and distance from artificial watering points in six habitats in the Kalahari Gemsbok National Park, and found that although changes in plant species composition occurred in the six different habitats, they were not related to the presence of artificial water points.

Monitoring of the vegetation around artificial watering points (windmills) in the Kalahari Gemsbok National Park
TL;DR: In this paper, vegetation changes around artificial watering points were monitored in the Kalahari Gemsbok National Park from 1978 to 1989, and it seems likely that a wet cycle commenced in 1988, which is reflected in higher rainfall and an increase in basal cover, presence, and density.
