Estimation of tree biomass reserves in tropical deciduous forests of Central India by non-destructive approach

摘要

The present study deals with the estimation of tree biomass by non destructive method in tropical dry deciduous forest (DDF) and tropical mixed deciduous forest (MDF) in 0.1 ha permanent plots, established at seven sites each in seven districts of state of Madhya Pradesh in central India. Tree volume was calculated using site specific volume equation. The biomass of each species was estimated taking tree volume and species specific gravity. The relationship between basal area and above ground biomass showed positive correlation for all sites and forest types. In general DDF holds higher density, basal area and biomass than MDF irrespective of sites. Significantly higher basal area (m(2) ha(-0.1)) was recorded in DDF (6.45 +/- 4.22) MDF (4.53 +/- 3.56). Average above ground biomass of both DDF and MDF of all sites were 31.8 t ha(-1) and 20.7 t ha(-1) respectively. Estimation of above ground tree biomass in the present study provides data for tropical deciduous forests covering a large part (24.66 %) of state for further use.
