Abstract
An investigation was made to determine the influence of alkali granite and bordering rocks on the distribution of plant species and plant communities. Six plant communities were successfully distinguished in the study area by using the TWINSPAN numerical classification technique, followed by refinement using the Braun-Blanquet technique. The plant communities could easily be correlated with specific habitat types. The results show that rock type as well as aspect (north and south facing slopes) influence the distribution of plant communities strongly. Groups of species which are reliable indicators for specific habitat conditions were also identified.

Breedweg word die plantegroei van hierdie gebied as Bankenveld geklassifiseer.^ Ander ondersoeke elders in die Bankenveld toon die invloed van die verskillende geologiese gesteentes op die verspreiding van plantge meenskappe duidelik aan.^-* Ook in die Vredefortdistrik is die verband tussen gesteente en plantegroei aangetoon, maar geen melding word van die plantge meenskappe op aikaligraniet gemaak nie
Klipperige rante is ’n gevolg van verskille in weerstandbiedendheid van die onderskeie gesteentes sowel as die plooiings en verskuiwings wat hier voorkom
Summary
An investigation was made to determine the influence o f alkali granite and bordering rocks on the distribution o fplant species and plant communities. Wat met kwartsiet geassosieer is, word uitsluitlik hoog op teen suidfronthellings aangetref. Die boomstratum is gemiddeld [3,1] m hoog, met ’n kroonbedekking van gemiddeld 20,3% (tabel 2). 2. Die N uxia congesta-Combretum mo//e-savanne Hierdie plantgemeenskap, wat met kwartsiet geassosieer is, is tot die warm, droe, klipperige en rotsagtige noordfronthellings beperk.
