    ENGLISH ABSTRACT: Pterocarpus angolensis is Namibia's most important indigenous timber species. The species is currently heavily exploited and more goal directed management needs to be implemented to ensure its continued survival in the country. However, the local knowledge of the species as well as its environment is very limited, making the development of management strategies very difficult. This study reviews the available literature on P. angolensis and the dry savanna woodlands in which the species occurs. The applicability of this literature to Namibian conditions is investigated through a vegetation study. The literature and results of the field study are then used to compile a model of the savanna system, with a link to a P. angolensis model. The mode is used to investigate the behavior of the savanna system and a P. angolensis population under a variety of conditions, and provides the basis management recommendations are formulated.
