Especially in the context of climate change these estimations with sufcient accuracy are pre-requisite for assessing the dynamics of carbon storage in particular ecosystems (Correia et al., 2010). All the carbon sequestration projects that deal with the accrual and long-term carbon sequestration estimation in vegetation and soil organic matter are dependent on these estimates. A better understanding of terrestrial carbon dynamics, and the valuable information and evidence generated by these project help in addressing the physical, natural, social and economic aspects of climate change in a more realistic way (Levy et al., 2004). Tree allometry establishes quantitative relations between some key characteristic dimensions of trees (usually fairly easy to measure) and other properties (often more difcult to assess). To the extent, these statistical relations established on the Abstract | In the recent past much of the stress has been given to the tree allometrics, above and below ground biomass and carbon sequestration databases to support the verifcation and development of greenhouse gas inventories under land use, land use change forestry (LULUCF). In this regard, empirical data of particular species for a specifc forest ecosystem is of utmost importance. In the present study volume and biomass allometric of naturally growing Cedrus deodara tree in dry temperate regions of Himalaya has been developed from the empirical data collected from four diferent locations with three sites each as representative of its naturally growing area. Destructive sampling including excavation of roots was carried for overall 60 trees. Te results revealed generic equations for above ground biomass and volume. However, statistical analysis pointed out several signifcant diferences in biomass allocation among C. deodara tree due to stand characteristics, highlighting the role and importance of microenvironment in regional and national forest inventories. Te study provides a comprehensive tool for estimating volume and biomass, thereby resulting in an accurate assessment of carbon sequestration and stocking in cedar dominated forest ecosystem in the region.
