Mgambo Forest Reserve 4.3.1.2 Species Abundance The most abundant species within vegetation plots was Combretum zeyheri representing 9.0% of all individuals sampled. This species was present within 16 vegetation plots and was the most dominant species in 5 vegetation plots (Table 5). Combretum zeyheri was common at low altitudes in open woodland and lowland forest margins. Dombeya shupangae was ranked as the second most abundant species within vegetation plots representing 6.4% of all individuals sampled. This woodland species was found in 12 vegetation plots. All of the most abundant species are widespread in their distribution and common in woodland and lowland forest. Table 5 Ranked abundance of tree and shrub individuals within vegetation plots.

Both of these are woodland species that are fire tolerant. Combretum zeyheri was also found in the most number of vegetation plots (51.6% of all plots). Albizia anthelmintica, Grewia bicolor and Dombeya shupangae were also found in a large proportion of the vegetation plots (45.2%, 41.6% and 38.7% respectively). These are also all woodland species. 4.3.1.4 Endemic Status Only 4 individual specimens from 1 species recorded in vegetation plots was endemic to the Usambara Mountains, this species was Cassia abbreviata. There were 12 species (11.8% of total) and 97 individuals recorded as near endemic. The majority of species recorded were therefore widespread in their distribution (Table 4). Endemic and near endemic species were found in greater numbers on the western side of the reserve (Figures 7 and 8).
