Er. Fuls et al., LOW THICKET COMMUNITIES OF ROCKY OUTCROPS IN THE NORTHERN ORANGE-FREE-STATE, South African journal of botany, 59(4), 1993, pp. 360-369
A phytosociological analysis of the low thicket vegetation of the rock
y outcrops of the Heilbron-Lindley-Warden-Villiers area (northern Oran
ge Free State) was conducted. Releves were compiled in 67 stratified r
andom sample plots. A TWINSPAN classification, refined by Braun-Blanqu
et procedures, revealed eight distinct plant communities. A hierarchic
al classification, description, plant-ecological interpretation and or
dination of the plant communities are presented.
