Table 6 summarizes <strong>the</strong> transect data for Garc<strong>in</strong>ia<br />

mannii. Obonyi I has by far <strong>the</strong> greatest populations <strong>of</strong> G.<br />

mannii, followed by <strong>the</strong> o<strong>the</strong>r lowland sites at<br />

<strong>Takamanda</strong> and Mfakwe. This species is poorly<br />

represented <strong>in</strong> higher-elevation Matene, as expected. In<br />

general, <strong>the</strong> mean dbh for G. mannii is high for this<br />

species at <strong>Takamanda</strong>, when compared with <strong>the</strong> Mokoko<br />

area where <strong>the</strong> mean dbh is 4.28, and <strong>in</strong>dicates m<strong>in</strong>imum<br />

Size class (cm)<br />

G. mannii shows a healthy cumulative size-class<br />

distribution, evidence <strong>of</strong> healthy regeneration and<br />

recruitment and few immediate impacts from<br />

exploitation (Figure 5). However, this population should<br />

be monitored, particularly with <strong>the</strong> recent <strong>in</strong>crease <strong>in</strong><br />

harvest<strong>in</strong>g <strong>of</strong> mature <strong>in</strong>dividuals.<br />
