- Title
ELEPHANTS, FIRE, AND FROST CAN DETERMINE COMMUNITY STRUCTURE AND COMPOSITION IN KALAHARI WOODLANDS.
- Authors
Holdo, Ricardo M.
- Abstract
The article discusses the effects of various disturbance factors on the vegetation in Kalahari sand woodland savanna in western Zimbabwe. Fire and frost do not play an important role when acting individually, whereas elephants can independently drive the vegetation to the scrub phase. According to the findings from a simulation model used to determine the effects brought about by disturbance factors such as fire, elephants and frost, under the current disturbance regime, tree basal area will decline by two-thirds over the next twenty years. The area will become overgrown with species, unsavory to elephants.
