Phytosociology of the B land type in the Newcastle – Memel – Chelmsford Dam area

This study forms part of the Grassland Biome Project. The results of a numerical classification (Twinspan) of 74 relevés compiled in the Bb and Bd land types of the Newcastle – Memel – Chelmsford Dam area, were refined by Braun-Blanquet procedures. The analyses revealed five major plant communities which may be divided into seventeen plant communities. A hierarchical classification, description and ecological interpretation of the plant communities are presented

The phytosociology of the grasslands of the Ba and Ib land types in the Pretoria–Witbank–Heidelberg area

An analysis of the plant communities of the grasslands of the Pretoria–Witbank–Heidelberg area is presented. Relevés were compiled in 148 stratified random sample plots. A TWINSPAN classification, refined by Braun-Blanquet procedures, revealed fourteen plant communities, and a hierarchical classification, description and ecological interpretation of these plant communities are presented. Each of these plant communities may be regarded as an entity with a unique species composition, and with specific environmental relationships and an inherent forage production potential. The identification, classification and description of these plant communities are not only important for management purposes, but also for the preservation of biotic diversity

The physical environment and major plant communities of the Heilbron–Lindley–Warden–Villiers area, northern Orange Free State

An analysis of the physical environment and associated major plant communities of the Heilbron–Lindley–Warden–Villiers area (northern Orange Free State) is presented. Relevés were compiled in 263 stratified random sample plots. Care was taken to avoid severely degraded areas. A Twinspan classification, refined by Braun-Blanquet procedures, revealed three distinct vegetation types. These vegetation types were subdivided into seven major plant communities. A hierarchical classification, description and ecological interpretation of the seven major plant communities are presented. The easily distinguishable major plant communities should be managed as separate ecological units in order to achieve optimal utilization and conservation of the vegetation of this part of the Grassland Biome

The plant communities and species richness of the <i>Alepidea longifolia- Monocymbium ceresiiforme</i> High-altitude Grassland of northern KwaZulu-Natal

As part of a vegetation survey of the grasslands of northern KwaZulu-Natal, this survey was conducted within the Alepidea longifolia-Monocymbium ceresiiforme grassland of high altitudes. Releves were compiled in 156 stratified random sample plots. The data set was classified using TWINSPAN. Subsequent refinement by Braun-Blanquet procedures produced 15 plant communities. Species richness was determined for each community. According to naturalness and species richness two communities were selected as being of conservation importance. An ordination algorithm (DECORANA) was also applied to describe the relationships between the vegetation units and the physical environment

The phytosociology of the northern section of the Borakalalo Nature Reserve

After classifications and descriptions of the southern and western sections of the Borakalalo Nature Reserve were published, a study on the phytosociology of the northern part was initiated. The study is aimed at providing an ecological basis for establishing an efficient wildlife management programme for the reserve. From a TWINSPAN classification, refined by Braun-Blanquet procedures, 15 plant communities, which can be grouped into six major plant communities, were identified. Descriptions of the various plant communities, include diagnostic species, prominent species and less conspicuous species of the tree, shrub, forb and grass strata. A hierarchical classification, description of the plant communities and a vegetation map are presented
