Development of Biomass Expansion Factor (BEF) and Estimation of Carbon Pool in Ailanthus excelsa Roxb Plantation

摘要

The article presents biomass and carbon stock for Ailanthus excelsa plantation in Dehradun Forest Division, Uttarakhand, India. Destructive sampling was used to calculate the biomass and carbon content of A. excelsa and Biomass Expansion Factor (BEF) was also developed for the species. The total biomass of A. excelsa was calculated as 126.07 t ha-1 with above ground biomass (AGB) 102.96 t ha-1 and below ground biomass (BGB) 23.11 t ha-1. Carbon content in A. excels was 58.52 t ha-1 i.e. 48.3 t ha-1 in AGB and 10.22 t ha-1 in BGB and soil organic carbon (SOC) was 46.27 t ha-1. Total carbon content (t ha-1) in different tree components were in the order: 40.27 (bole)>10.22 (root)>5.36 (branch)>1.61 (bark)>0.73 (leaf)>0.33 (twig). BEF value calculated for the species was 1.23.
