7. DIVERSITY AND DISTRIBUTION OF CLIMBING PLANTS IN TROPICAL EVERGREEN FOREST OF NORTH ANDAMAN ISLANDS_ INDIA By ASHUTOSH GHOSH
The present study examined the floristic diversity, dominance, abundance and IVI of climbers and lianas species in the tropical evergreen vegetation in North Andaman forest. A total of 1098 climbing plants belonging to 115 species, 77 genera, and 34 families were identified. These consisted of 67 liana and 48 herbaceous climber species. Stem twinning was the most predominant (44.35%) climbing mechanism. The dominant species recorded from this forest were Calamus andamanicus (IVI-16.7), Gnetum scandens (IVI-10.75) and Calamus viminalis (IVI-10.05) respectively. Most of the species were randomly distributed whereas some showed clumped distribution.
