checkpoint records from Kibiti, stump survey results from selected Forest Reserves, and sawmill records<br />

Species composition of <strong>timber</strong> recorded at Kibiti checkpoint<br />

During <strong>the</strong> three-month period from October 2001 to January 2002, over one-half of <strong>the</strong> round wood<br />

recorded was declared as Hymenaea verrucosa, followed by Pterocarpus angolensis, Trichilia emetica,<br />

Afzelia quanzensis and Swartzia madagascarensis (Table 16 and Figure 17). These were <strong>the</strong> same top<br />

five species recorded from harvest licences issued in <strong>the</strong> study area during 2001. Toge<strong>the</strong>r, <strong>the</strong>se five<br />

species accounted for over 90% all round wood passing though Kibiti checkpoint, again closely<br />

comparable to <strong>the</strong> figure of 87% from harvest licences. Similarly, <strong>the</strong> proportions by class were very<br />

similar between <strong>the</strong> two data sources (Figure 11).<br />
