The aim of this study is to determine the coarse root biomass and to reveal the relationship with some habitat and stand properties in the beech stands in Sinop. The study included 20 sample plots of natural pure beech stands in Sinop Forestry Chiefdom. Diameter at breast height, stand age, tree height and number of trees were measured and rooting profile (1x2m) in the plots was examined. Coarse roots extracted from each depth classes with 30 cm depth. We collected soil samples from rooting profiles and analyzed some of the physical and chemical properties of soil. The soil of the study area has a high clay content, and it is nearly doubling for soils deeper than the 30 cm. The mean coarse root biomass is 16.7 ton/ha and about 93% of it is distributed in 0-30 cm depth. There was no difference between shadow and sunny aspects in terms of coarse root biomass. While coarse root biomass has significantly related to basal area, clay and sand content of the soil and available field capacity, there is no relationship with diameter, age, height and number of trees. Distribution of the coarse roots mostly close to soil surface within first 30 cm depth may be due to heavy textured soils. These data could be used for estimating the amount of coarse root biomass and distribution depth of beech forests close to sea level with heavy clay soils.
