Secondary tropical forests sequester atmospheric CO2 at relatively faster rates in vegetation and in soil than old-growth primary forests.Spatial understanding of bio-mass and carbon stocks in different plant functional types of these forests is important.Structure,diversity,composition,soil features and carbon stocks in six distinct plant functional types,namely:Moist Mixed-Deciduous Forest,Peninsular Sal Forest(PSF),Semi-Evergreen Forest(SEF),Planted Teak Forest,Bamboo Brakes(BB),and Degraded Thorny Shrubby Forest were quantified as secondary tropical decid-uous forests of the Chandaka Wildlife Sanctuary,Eastern Ghats of Odisha,India.Seventy-one species≥10 cm Girth at breast height(GBH)were recorded,belonging to 38 fami-lies and 65 genera.Above-ground biomass carbon and soil organic carbon ranged from 2.1-72.7 Mg C ha-1 and 20.6-67.1 Mg C ha-1,respectively,among all plant functional types.Soil organic carbon and important value index were positively correlated with above-ground biomass carbon.Maximum carbon allocation was in SOC pool(51-91％),followed by the above-ground biomass pool(9-52％),indi-cating SOC is one of the major carbon sinks in secondary dry forests.The results highlight the importance of second-ary tropical deciduous forests in biodiversity conservation and ecological importance in reducing greenhouse gases.
