Anthrax was associated with the death of a large number of animals in the Selous Game Reserve. The significance of this disease to the populations of these animals was of concern to the reserve's management. Models are presented of the evolutionary effects of four host-pathogen relationships. Based on a demographic study of the wildebeest and a study of the characteristics of the disease, the anthrax-wildebeest relationship was compared with the models. The results of the study indicate that even though anthrax was responsible for the death of approximately 10% of the wildebeest, it had a balanced relationship with the population. The pathogen was probably an asset to its host population's continued existence rather than a hazard, as its mortality was associated with animals that appeared to be a disadvantage to the wildebeest population. If the management of the reserve wished to reduce the occurrence of anthrax, it is suggested that they reduce the number of wildebeest older than calves. In addition to maintaining a stable age configuration, this would improve the quality of the habitat, reduce the number of animals in poor condition, and thus reduce the number dying of anthrax. In addition, I deal with several other topics in Appendices. / Science, Faculty of / Zoology, Department of / Graduate

The dissertation presents the results of a study of the role of decentralisation and community participation in natural resource management in Tanzania. It analyses whether the shift of central government power to decentralised government units and the participation of local communities at village level result in more effective and more sustainable management of natural resources, wildlife in particular. The study uses Songea District and the Selous Conservation Programme south of Tanzania as a case study. As the examination of the origins and meaning of community-based natural resource management and decentralisation and the analysis of international experiences show, both approaches have been adapted in a number of countries in sub-Saharan Africa. The government of Tanzania, with the support of a wide range of donors, is implementing an ambitious Local Government Reform Programme. The Selous Conservation Programme, jointly administered by the Tanzania Wildlife Division and GTZ, is promoting community-based conservation in villages bordering the Selous Game Reserve. The new Wildlife Policy, 1998, aims at the country-wide implementation of community-based conservation. Linkages between local government reform and improved environmental management are weak from insitutional, legal and technical points of view. On the other hand, the country has a policy environment that is highly supportive to decentralised environmental management and there is potential for improvement at both local and national levels. Songea District Council has defined the sustainable management of natural resources and the environment as one of its development priorities. Concerning the implementation of the Local Government Reform Programme, the district faces some problems and difficulties. Lack of human capacity and insufficient financial resources constrain the decentralisation process. Until now, up to about 50 villages bordering the game reserve have established their Wildlife Management Areas utilising their hunting quota. Due to insufficient and overdue legislation, the communities cannot fully make use and benefit from their wildlife resource. If remained uncorrected in the near future, the sustainability of community-based conservation programmes is threatened. / Thesis (M.Dev.Studies)-Univeristy of Natal, Durban, 2001.
