Effect of vegetation structure and species composition on above ground biomass and carbon in forests of Central Western Ghats, India

The present study was carried out to quantify the changes in tree diversity and aboveground biomass in three different forest types existed in the Kodagu district of Central Western Ghats. Data on species richness, diversity, composition, above ground biomass (AGB) of trees, shrub and herbs, carbon stock were collected from 120 sample plots of 400 m 2 . Results revealed that evergreen forests recorded higher richness (141 species), diversity, density, basal area, biomass and carbon than other two forest types of the district. AGB from three forest types ranged from 175 to 233 Mg ha–1 . Our study shows that not only density that governs the AGB, however basal area, an important factor contributing to AGB and carbon stock. Trees in higher girth classes particularly, > 180 cm gbh, contained higher amount of biomass carbon and removal of such trees will have considerable impact on carbon dynamics of the region. | Effect of vegetation structure and species composition on above ground biomass and carbon in forests of Central Western Ghats, India
