Abstract
Accurate estimates of forest biomass to assess the ability of forests to sequester atmospheric carbon of very important issues in the management of forests. The present study aimed to estimate the biomass of single base Quercus brantii trees were terrestrial photogrammetry using nondestructive methods. The study was conducted in the Chaharmahal va Bakhtiari, the first 32 single base Quercus branti trees in different class diameter selection and of each trees two photos in the direction perpendicular were taken. Then the scale was calculated for each photo and determined the Volume of different components of trees (trunk, main branches, branches and foliage (Crown)). With the sampling of the various components of tree, calculated density, and biomass measured for different components and estimated biomass of terrestrial photogrammetry method was compared with biomass obtained from cutting and weighing. Results showed a significant difference is not between the estimated biomass of terrestrial photogrammetry method with the most accurate method to estimate the biomass. This study, accuracy and efficiency terrestrial photogrammetry method shows in the above ground biomass estimation in growth form single base Quercus brantii.
