A reconnaissance survey of the vegetation of the dolomitic region in the Potchefstroom-Ventersdorp-Randfontein area, South Africa
Bezuidenhout, H.; Bredenkamp, G. J.
As part of a phytosociological research programme on the synthesis of the vegetation of the western Grassland Biome in South Africa, the plant communities of the dolomite region in the Potchefstroom-Ventersdorp-Randfontein area were investigated. A numerical classification technique (TWINSPAN) was used to derive a first approximation of a vegetation classification. This classification was refined by Braun-Blanquet procedures. In this way an ordered phytosociological table was constructed effectively, and the analysis revealed ten plant communities. A hierarchical classification, description and ecological interpretation of the plant communities are presented. Although most of the distinguished plant communities have never been described before, a formal syntaxonomical classification is avoided, as too little is presently known of the phytosociology of the western grasslands of South Africa. This classification should however contribute to the ultimate goal of a comprehensive syntaxonomical synthesis of the South African grasslands.
