Abstract:
In this study, the multidisciplinary epistemology of ethnobotany is  reviewed  within the wider context of ethnoecology and indigenous knowledge systems. The major problems derived from this theoretical framework cover aspects of the relationship between cultural groups and their natural environment - particularly the botanical component of the latter. Problems and critical questions about this relationship were investigated in selected areas of the Bushbuckridge district, which are inhabited by a number ofTsonga-Shangana communities. Salient aspects of the natural habitat in the study area are discussed with special reference to the vegetation,  climate  and  soil types. A proper understanding of the culturally-based exploitation of plant resources necessitates a sound 
knowledge of the culture concerned, including relevan t aspects of its value-system and cosmology. 
In  this review, emphasis  is  placed on  those aspects of culture that are directly concerned with the utilisation of plant resources. The latter include a wide range of economic, technological and medicinal  uses. Specimens  of 200 plants were collected and identified by the University  of  Limpopo  Herbarium. The uses of every species are described. Systematised tables of plant uses  are  presented, as well as comparative lists in which selected uses are compared to those of other cultures in which the same species are used. The effects of plant utilisation, as well as indigenous forms of resource management, are also discussed. Recommendations are made on how to 
counter the process of  environmental degradation which is caused by over-exploitation .
