Jp. Coetzee et al., AN OVERVIEW OF THE PHYSICAL-ENVIRONMENT AND VEGETATION UNITS OF THE BA AND IB LAND TYPES OF THE PRETORIA-WITBANK-HEIDELBERG AREA, South African journal of botany, 60(1), 1994, pp. 49-61
An analysis of the physical environment and associated vegetation of t
he study area is presented. Releves were compiled in 265 stratified ra
ndom plots. Care was taken to avoid severely disturbed areas and ecoto
nes. A TWINSPAN classification, refined by Braun-Blanquet procedures,
revealed eight vegetation units which can be regarded as distinct ecol
ogical units. A hierarchical classification, description and ecologica
l interpretation of the eight vegetation units are presented. These ec
ological units should be taken into account in the compilation of mana
gement programmes for the natural resources of the study area.
