Die Fitososiologie van die Villiers-Grootvlei-omgewing

Abstract

The vegetation of the Villiers-Grootvlei area was classified using Braun-Branquet procedures. The polythetic divisive program TWINSPAN was used for a first classification which was then refined. Land Types and geology were criteria used to stratify the study area. Separate phytosociological tables were generated for the Ib, Ba, Bb and Ea Land Types. The plant communities were described and interpreted ecologically. A synoptic table showing the hierarchical relationship among plant communities was compiled. The habitat-vegetation interactions were indicated by means of DECORANA ordination.
