This study was carried out to investigate above-ground biomass of white poplar (Populous alba L.) plantations by four different plant spacing (0.5 × 0.5, 1 × 1, 2 × 2 and 4 × 4 m) in south west of Iran. After taking inventory, 10 trees were selected from each density section at one-hectare area (totally 40 stems). The tree's characteristics including diameter at breast height (DBH), total height, and crown diameter were measured. Then measured trees were felled down in order to measure the wet and dry weight of their different organs. After sampling from all the parts, carbon stock in the structure of this biomass species was obtained and the results showed that the most amount of biomass among the components per hectare is related to the bole wood and most amounts of biomass was related to the 0.5 × 0.5 m and 1 × 1 m planting spaces.
