Phytosociology, vegetation structure and landscapes of the central district, Kruger National Park

Abstract

Variation within the Kruger National Park Vegetation, at the broadest level, is essentially four dimensional. Twenty principal vegetation regions may be delimited by superimposing these four major types of variation. A Braun-Blanquet Type phytosociological classification identified: 15 differential species groups that are each shared by more than one association; a group of species that are essentially exclusive to individual associations; two groups that occur either too generally or too sporadically to form differential groups; and 12 associations. A new approach to classifying Bushveld physiognomic structure is offered. This system is based simply on canopy cover classes. regime at Emphasis accompanying terminology, provided. A hierarchical three levels, and detail may using Braun-Blanquet be varied and a suited to casual and formal use, is system for classifying vegetation delineated ecosystems and their entire abiotic and vegetation components is offered. This system integrates several ecologically important climatic, physiographic and vegetation classifications currently in use. Twelve landscapes are accordingly identified and their climates, physiographic and vegetation patterns and medium to large herbivore faunas described. The inventory is offered as an information base and as a means of within and between group communication to scientists, conservation managers, information officers and public.
