The carbon density of different tree parts is not often measured directly, but generally assumed to be 50% of dry weight. In this study we try to analyze those assumptions and determined the effect different regression equations on carbon sequestration for Tectona grandis, Vachellia nilotica, Madhuca indica, Dalbergia sissoo. The present study aims to estimate the above-ground biomass (AGB) and carbon sequestration in 18 sampling plots of 30 × 30 m 2 size, at different sites in northern plains (Uttar Pradesh) India.
