Frontier Tanzania Savanna Research Programme

species recorded from the vegetation plots were absent from the regeneration plots,whilst only 15 regeneration species were not found in the main vegetation plots.Thirty-six of the species from Nambiga were plants usually associated with riverinewoodland or moist forest, whilst the remainder consisted of a variety of drywoodland, open grassland and secondary forest species (Palgrave 1983, Beentje1992).Vegetation height, mean DBH, species richness and abundance of dead trees showedno relationship with proximity to the reserve boundary, with values evenly distributedacross all plots. There was also no clear pattern in the distribution of poles and timbertrees, with both occurring at a relatively uniform abundance throughout the reserve(Figures 3.1 and 3.2). There was, however, a trend for the plots in the north-east of thereserve to have the highest density of poles (Figure 3.2).3.3.2 Disturbance surveySome evidence of logging was found in 20 of the 48 plots and of these occurrences,six were recent.9
