Sweet chestnut is the only species naturally found in Europe and Asia Minor. The species is mainly distributed over the North Anatolia (Black Sea Coast), Marmara and Western Anatolia in Turkey. Within the scope of the study, it was selected eight sample plots that located in Rize, Sinop and Bartın Forest Management Directorates. Firstly, general and special site properties of sample plots were determined. Stand profiles were taken in the size of 20×30 meters (600 m2) and 20×50 meters (1000 m2). The crown projection, the length, the breast height diameter and the height the base of crown of all the trees were measured in each sample plots. Stand profiles and their crown projections were drawn for each sample plot, after that the average of tree height and breast height diameter, total basal area, the total number of tree in one hectare and crown closure were found. In the study, chestnut stands were nearly 50-60 years old. The total number of trees in one hectare was found as 427 in Bartın, 433 in Sinop and 432 in Rize. Total basal area of chestnut stands located in Rize, Sinop and Bartın occurred as 32.13 m2/ha, 31.76 m2/ha and 35.73 m2/ha, respectively. The average of tree height varied between 12.9 to 18.9 m and the average of tree diameter ranged from 30.02 cm to 35.73 cm. Sweet chestnut usually forms mixed stand types with some broadleaved species such as beech, alder, hornbeam. Mixed forms are located as clump and group rather than individual.
