Estimation of biomass, carbon sequestration and leaf area of Acer monspessulanum in Middle-Zagros, case study: Ghaleh Gol forests in Lorestan province

This research aimed to investigate carbon sequestration and biomass of Acer monspessulanum stands in Ghale Gol region. For this purpose, 30 Acer monspessulanum trees were selected using random sampling method, and quantitative characteristics including big and small crown diameters, tree height, crown height and DBH of them were measured and recorded. Then, of all geographical aspect 5 leaves at a height of 1.5 meters of crown tree were collected. At first wet weight of leaves were measured, then dried leaves were weighted again. Amount of carbon was obtained after burning leaves and weighing ash of dry leaves. Also, amount of carbon dioxide absorbed by the leaves after applying 3/67 in the amount of organic carbon stored in the leaves was estimated. The results showed that biomass average, carbon sequestration and the average amount of carbon dioxide absorbtion, were measured 8.17, 8.57 and 31.45 kg per ha respectively, and the leaf area was estimated 0/868 m2 / ha. Probability level, there is a significant difference between the average of carbon sequestration and biomass, in four geography tree crown aspects. However, at 95% probability level there isn’t significant difference between the average leaf areas, at four geography aspect. Amount of leaf biomass in the east aspect and amount of carbon sequestration in the western aspect were higher than other aspects.
