4.3 Results<br />
4.3.1 Quantitative vegetation analysis<br />
4.3.1.1 Vegetation Plots<br />
A total of 31 50 x 20m vegetation plots were established. By far the most dominant vegetation<br />
type within vegetation plots was found to be open woodland (65% of plots), with lowland forest<br />
found in just 16% of plots. There was none submontane forest vegetation plots. Almost 65% of all<br />
vegetation plots had an average canopy height of less than 10m, and there were no vegetation<br />
plots recorded with canopy heights greater than 20m. A total of 68% of vegetation plots had been<br />
affected by fire. The average slope for all accessible vegetation plots was moderately steep at 20.5<br />
degrees. Vegetation plot descriptions are summarised in Appendix 3 and a vegetation map shown<br />
in Figure 6.<br />
A total of 858 individuals, representing 31 families and 101 species were recorded in thirty-one<br />
20m x 50m vegetation plots at 0.25% sampling intensity. Species are described, where adequate<br />
information exists, in terms of their ecological type, their habitat and their endemic status.<br />
Nomenclature follows Iversen (1991b), the Flora of Tropical East Africa (Polhill, 1988) and the<br />
LEAP database (Knox, 2000). Table 4 presents a checklist of these tree and shrub species.<br />
