Description
Summary:	Urban forests with various ecological and environmental benefits are one of the most important ecosystems, therefore, study of ecological parameters in urban forests is essential. In this research, one of the oldest urban forests of Sanandaj city, Taileh, with area of 1.7 ha was selected. Direct method (leaf gathering from the crown) and 100% inventory method was used to estimate leaf biomass and leaf area index (LAI) of Celtis caucasica, which was the main species. Firstly, different quantitative variables such as diameter at breast height, collar diameter, tree height, crown length and small and large diameter of crown were measured. In addition, the leaves of one fourth of the tree crown were picked off and after weighting, their dry weight were measured in laboratory. Gravimetric method was applied for calculating LAI, in which the relationship between leaf area and it`s dry weight used to estimate the total area of whole tree leaves. Allometric equations were calculated for estimation of leaf biomass and LAI. Based on the results, the mean values of leaf biomass, Specific Leaf Area (SLA) and LAI were 37 kg, 103.5 cm2/gr and 3.7 for C. Caucasica, respectively. The compound variable, DBH2×H, was the most effective factor to estimate the leaf biomass (R2=0.69), but in LAI equation, the root of DBH had the main role (R2=0.72).
