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 />
impacts from exploitation.<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 />
