R. Interestingly, none of the three large tree species (Milicia excelsa, Khayaanthotheca and Xylopia parviflora) were found in the regeneration plots. It is evidentfrom these results that both types of plot are necessary to fully describe thecomposition and structure of forest vegetation because many of the plant species werenot recorded in both vegetation and regeneration plots.Many of the trees in Nambiga F. R. are important for timber, fuel, food, nitrificationand soil conservation (Table 3.2). This list summarises the uses of these trees from thewhole of Tanzania (Mbuya et al. 1994) and indicates the potential of many of thetrees to provide resources to the local community. Further community research aroundNambiga F. R. may discover new uses for some of these trees.17
