A major global challenge is the urgent need to bend the curve of rising atmospheric carbon dioxide (CO2) concentration. Carbon (C) pools in forests play an important role in regulating the regional and global C cycles. In this study, C stocks of all the pools {live biomass (trees and non-tree vegetation), detritus (deadwood and forest floor litter), and soil} were assessed from six vegetation types {3 natural forests (tropical dry deciduous, semi-evergreen and evergreen) and 3 plantations (teak, rubber and areca nut)} in Kanyakumari Wildlife Sanctuary, Western Ghats, India. The total ecosystem C stock averaged 262.7 ± 56 Mg C ha-1 and ranged between 94.7 and 506.8 56 Mg C ha-1. Soil was the major C pool in tropical dry deciduous forest and areca nut plantation, whereas biomass was the largest pool in other vegetation types. The C stocks of teak and rubber plantations were comparable with those of dry deciduous and semi-evergreen forest types respectively. The C stocks were significantly positively correlated with stand density, basal area and mean annual precipitation, and negatively correlated with mean annual temperature. The present study would improve our understanding on C allocation patterns at ecosystem-level in different vegetation types of Western Ghats, and can be used for ecosystem restoration and forest management programmes to enhance C sequestration.
