Title: Classification of the vegetation of the B land type in the north-western Orange Free State
Abstract: An analysis of the vegetation of the B land type, covering 928 000 hectares in the north-western Orange Free State is presented. More than 80% of the area has been ploughed. Relevés were compiled in 104 stratified random-sample plots in the remaining natural vegetation. A TWINSPAN classification, refined by Braun-Blanquet procedures revealed seven plant communities which may be classified under four major communities. All communities are related to specific environmental conditions. Descriptions of the communities are given. 'n Analise van die plantegroei van die B-landtipe, wat 928 000 hektaar van die noord-westelike Oranje- Vrystaat beslaan word aangebied. Meer as 80% van die gebied is geploeg. Relevés is in 105 gestratifiseerde ewekansig-gekose monsterpersele saamgestel in die oorblywende natuurlike veld. 'n TWINSPAN-klassifikasie verfyn deur die Braun-Blanquet-tegnieke toon sewe plantgemeenskappe, wat in vier hoof-gemeenskappe gegroepeer kan word. Die geïdentifiseerde gemeenskappe kan verklaar word aan die hand van spesifieke omgewingsfaktore. Die plantgemeenskappe word beskryf.
