Species Diversity and Tree Regeneration Patterns in Tropical Forests of the Western Ghats, India

Table 1

Dominant trees (first three) and their densities (trees ha−1) in three different growth phases of six vegetation types. International (UNESCO) and regional (Champion and Seth, 1968*) terminology of vegetation types used. See “regeneration” in Section 2 for procedure used to distinguish dominant species.
