The objective of this study is to estimate the stem volume per single tree for Alnus glutinosa Gaertn subsp. barbata (C.A. Mey.)Yalt. stands of East The Blacksea Region. Double Entry Volume Table was constructed by means of the material collected at the 510 sample trees, were choosen in 55 temporary trial plots taken in the pure, even aged, untouched, normal stocked and naturally grown stands of the Alnus barbata between Persembe and Hopa-Kemalpasa. Several mehods were in evaluation of material and constructing the table. It was based on Regression Methods in obtaining Double Entry Volume Table. 6 volume models were choosen for this purpose.
