The height of a tree is important for assessing tree volume and site index. Diameter of breast height-tree height releation equations are often used to predict the mean tree height for trees in case only diameter at breast height is measured. This study aim describes between the tree heights with diameter of breast height relationships for artificially grown black locust (Robinia pseudoacacia L.), Anatolian black pine (Pinus nigra Arnold. subsp. pallasiana (Lamb.) Holmboe) and Taurus cedar (Cedrus libani A.Rich.) in Lakes Region. It's presented a set of height-diameter equations for four tree species using data obtained from artificially grown stands in Lakes Region. Monserud's (1975) equation is used bacause of this equation is a flexible form that readily fits many height-diameter datasets. Nonlinear regression techniques were used to test the equation. The resulting equations provide a reasonable means of predicting unknown tree heights, given diameter of breast height, for Black locust, Anatolian black pine and Taurus cedar tree species in Isparta and Burdur Regions. This height-diameter equation can be used to avoid time-consuming task of measuring heights of all individual trees in inventory for this species.
