Assessment of Plants Biodiversity in Innerline Reserve Forest, Hailakandi, Assam, India

The study deals with the “Assessment of Plant biodiversity of Innerline Reserve Forest, Hailakandi (Assam)” India. that was carried out in six sites. A total of 54 species of trees belonging to 32 families with 2,303 individuals, 17 species of shrubs belonging to 13 families with 2,195 individuals and 27 species of grasses and herbs belonging to 13 families with a total of 1,595 individuals were encountered. Quadrate size of 400 m2 for trees, 100 m2 for shrubs, 20 m2 grasses and herbs. Compared to all the six sites, Site-III shows the highest Basal area (243.67 m2). In terms of IVI, Tectona grandis was found to be the most dominant tree species, Clerodendrum infortunatum was found to be the most dominant shrub species and Oplismenus compositus was found to be the most dominant grasses and herb species. In aspects for all the sites it can be concluded that Site-III showed the highest value for Shannon-Weiner Diversity Index (Hˈ) (3.2) for trees species, Site-V showed the highest value for Shannon- Weiner Diversity Index (Hˈ) (2.27) for shrubs species and Site-III showed the highest value for Shannon- Weiner Diversity Index (Hˈ) (2.32) for grass & herb species.
