The paper contains the results of analysis of the herb layer carried out under different habitat conditions of two forest associations. Camparative studies of the floristic content and an analysis of the homogeneity of the herb layer were conducted with the use of objective statistical methods and a numerical classification technique.

Normal association-analysis was carried out on data collected in the Jack Scott Nature Reserve in the Central Bankenveld of the Transvaal. As the method was found inadequate for obtaining optimal definition and arrangement of plant communities, it was supplemented by the Braun-Blanquet Table Method, which served as a substitute for inverse and nodal analyses. This led to a better understanding of the vegetation of the Reserve. Because association-analysis is strictly hierarchical, presentation of inter-group relationships and interpretation of vegetation-habitat relationships are limited. It is argued that the monothetic character of normal and inverse association-analyses is a further limitation and although this is com­pensated for by nodal-analysis, valuable information is discarded as peripheral in the latter process.

There is currently no detailed classification and description of plant communities in Khutse Game Reserve (KGR), Botswana, using phytosociological techniques. The main aim of this study was to classify and describe plant communities in KGR. Classification and description of plant communities will help in understanding the plant ecology of KGR. Braun-Blanquet sampling method was applied in 91 stratified random relevés. Nine plant communities were identified and classified using Modified TWINSPAN which is contained in JUICE program. The results showed that there was a statistically significant difference in percentage cover of herbaceous plants between the different plant communities. Schmidtia pappophoroides-Stipagrostis uniplumis and Heliotropium lineare-Enneapogon desvauxii communities had higher cover (%) of herbaceous plants than other communities. Catophractes alexandri-Stipagrostis uniplumis community had the highest cover (%) of shrubs. There was no statistically significant difference in plant species diversity (Shannon-Wienner Index) and species evenness between plant communities, but there was a statistically significant difference in plant species richness between the different plant communities. Dichrostachys cinerea-Grewia flava community, Senegalia mellifera subsp. detinens-Maytenus species community and Catophractes alexandri-Stipagrostis uniplumis community had lower number of species, whereas Vachellia luederitzii var. retinens-Grewia flava community had the highest number (46) of plant species. This study will help the Department of Wildlife and National Parks (DWNP) to develop an updated and informed Management Plan for the reserve, which takes cognizance of the plant ecology of the reserve.

Four major themes can be identified over the period 2008—2009: (1) the increasing use, sophistication and resolution of remote sensing techniques and the application of these methods to assessment of biomass, C-balance and biosphere-atmosphere interactions; (2) continued interest in dynamic change processes affecting individual species and plant communities, and the changing proportions of tree, shrub and herbaceous components; (3) the nature, impact and management of fire; and (4) increasing awareness of the importance of soils and soil moisture in shaping the nature and distribution of vegetation, particularly at local scales.
