A plant ecological study was conducted in the grasslands of Transkei to develop a better understanding of the distribution, structure and composition of the plant communities found in the area. The agricultural sector in developed and rapidly developing areas of southern Africa is faced with problems like veld deterioration and the loss of natural areas that effectively contribute to the depopulation of rural areas. The Grassland Biome Project was initiated to address the problem of increased destruction of natural resources because the most suitable area for agriculture falls within the grasslands of South Africa. The aim of the Grassland Biome Project is to integrate knowledge, comprehension and expertise, which will enable scientists to forecast the results of the available options of grassland management programs. Vegetation of Transkei forms part of this project. The study area (Transkei) borders on the kingdom of Lesotho in the north and Indian Ocean in the southeast. In the northeast it borders on KwaZulu-Natal and in the northwest, and in the west on the eastern Cape Province. Relevés were compiled in 379 random sample plots and four major plant communities, namely: Bush and Grassland vegetation of drier areas, Wet and Disturbed grassland, Grassland of Undulating Areas, and Moist Grasslands on Flat Plains, were found. The vegetation was classified by means of TWINSPAN and Braun-Blanquet procedures were found. The vegetation was classified by means of TWINSPAN and Braun-Blanquet procedures. / Dissertation (MSc)--University of Pretoria, 2005. / Geography, Geoinformatics and Meteorology / Unrestricted

A vegetation survey, based on plant communities, was conducted on the Ezemvelo Nature Reserve. The aim of the study was to identify, describe and classify plant communities of Ezemvelo Nature Reserve, and interpret them ecologically. The information derived from this study can then be used in the management of the Reserve. The floristic composition and habitat information were recorded in 210 sample plots. The data was captured in the TURBOVEG database and classified using the TWINSPAN numerical classification algorithm. The resulting phytosociological tables were compiled and organised using the MEGATAB computerised table management programme according to Braun-Blaunquet procedures. The data was also subjected to a Detrended Correspondence Analysis (DECORANA), processed by the PCOrd numerical ordination programme, to confirm the results of the classification. The ordination also illustrates any environmental gradients controlling the existence and distribution patterns of the different plant communities. Twenty-two major plant communities and 4 sub-communities were identified, described, and ecologically interpreted. The localities of the plant communities are indicated on map, compiled by using GIS. The plant communities on the Reserve are distributed in a mosaic of woodlands, grasslands and wetlands, based on the heterogeneous habitats created by the variations in topography, which is typical of Bankenveld vegetation. / Dissertation (MSc (Botany))--University of Pretoria, 2007. / Plant Science / MSc / unrestricted

The vegetation of the sand dunes on Long Beach, Vancouver Island, was studied on 116 sample plots. The purpose of this study was to describe the floristic and edaphic characteristics of the plant associations, to determine the major environmental factors controlling the distribution of the plant communities and to study the successional trends of the vegetation. The vegetation was described using the analytical and synthetical methods of the Zurich-Montpellier school of phyto-sociology. This thesis describes seven plant associations and four variants. The vegetation units are as follow: A. Foreshore habitats 1. Cakiletum edentulae B. Blowout habitats 2. Poetum macranthae a. poosum macranthae , b. abroniosum latifoliae 3. Arctostaphyleto-Rhacomitrietum canescentis C. Habitats of the mobile dune ridge 4. Elymetum vancouverensis a. ammophilosum arenariae b. elymosum vancouverensis D. Habitats of the dune slack and stable dune ridge 5. Aireto-Ceratodontetum purpurei 6. Arctostaphyleto-Eurhynchietum oregani 7. Hetergenous communities i n moist dune slack habitats E. The dune forest habitat 8. Piceeto-Gaultherieto-Maianthemetum dilatati Important environmental factors which control the distribution of these associations are the level of winter and storm tides, wind, the amount of sand burial and blowout that occurs in the habitat and the amount of available soil water. The first stages of succession begins in the unstable habitats of the Elymetum vancouverensis and Poetum macranthae. With stabilization of the habitat, these associations are succeeded by the Aireto-Ceratodontetum purpurei and the Arctostaphyletum-Eurhynchietum oregani in exposed habitats and the Arctostaphyleto-Rhacomitrietum canescentis in habitats well protected from wind. All vegetation eventually reaches the climax Piceeto-Gaultherieto-Maianthemetum dilatati. / Science, Faculty of / Botany, Department of / Graduate
