Abstract: 
Tilia is a very valuable species of north woods of Iran. To regarding the importance of Tilia, the evaluation of quantitative and qualitative characteristics, multiplication and selecting the best site are main purposes of this study. Thus, the wood sites, Garmabdasht and Gharnabad, in Gorgan, were chosen. In each site four ha square sampling area were selected. The factors measured in each sampling area are: quantitative characteristics (number per ha, total height, dichotomous ramification height, the first branch height, the crown initiation height, crown diameter and diameter against chest), qualitative properties (canopy, crown symmetry, bending and convolution percentage) and Tilia multiplication. Tilia spreads in a wide range of environmental conditions was observed. The data, analyzed by T. Test and Spss statistical software showed no significant difference between number per ha, total height, dichotomous ramification height, crown initiation height and crown diameter but significant difference between diameter against chest and the first branch height in both sites. No significant difference was shown between qualitative properties (canopy, crown symmetry, bending and convolution percentage). Multiplication data in both sites indicated that Tilia multiplication was insignificant between plants lower than 1.3m but it was significant between ones higher than 1.3m. Continental studies of evaluated regions indicated that there are humid climate with moderate winter in Garmabdasht's wood and humid climate with cool winter in Gharnabad's wood. Eventually it seems that regarding quantitative characteristics, Gharnabad is a more suitable site than Garmabdasht for Tilia growing, but Garmabdasht is better for multiplication than Gharnabad.
