Estimation of Carbon Estimation of Carbon
Stock in Indian ForestsStock in Indian Forests
Salient Features of the Methodology
• most comprehensive assessment so far
• a GIS approach
• based on over 15,000 sample plot data from National
Forest Inventory
• First ever forest type map (Champion & Seth Classification)
has been used
• stratification based on forest cover (canopy density) and
Forest Type
• strata specific volume equations/ expansion factors and
specific gravity used
• carbon stocks for the years 2007 and 2005 have been assessed

-strata specific primary data generated for each
component through a country wide special study
-samples of soil for SOC (from the sample plots of NFI
