This study suggests that there is a strong positive correlation between overall species<br />

diversity and rattan diversity and the richness <strong>of</strong> the rattan flora may reflect that <strong>of</strong> the<br />

wider vegetation <strong>of</strong> a sample area. As such, rapid assessments <strong>of</strong> key taxa, such as<br />

rattan palms, might provide a cost-effective preliminary means <strong>of</strong> contributing ti the<br />

assessment <strong>of</strong> overall forest diversity.<br />

There does not seem to be a particularly strong influence <strong>of</strong> edaphic factors on rattan<br />

diversity and abundance as is reported in SE Asia (Nur Supardi, 1999). Despite the<br />

variation in soil type between the three sites, there is no significant variation in rattan<br />

diversity based on this, although this quite probably accounts for the variation in<br />

species composition between the three sites. Hence, the free-draining basaltic soils <strong>of</strong>
