Studies were carried out in natural fir stand of Gorgany Range (Eastern Carpathians - Ukraine) in 1989, Till 1980 the fir stand had been managed by assorted-selection cutting system. From 1980 the stand has been under strict protection as a result of including it in State Carpathian Natural Park. Investigated stand is characterized by high mean stand volume - 942 m3/ha (Tab. 1) when its species composition consist of fir - 88%, spruce — 8% and beech - 4%. Tree distribution in diameter classes (Tab. 1, Fig. 1), stand statistical parameters (Tab. 2) and comformability to Liocourt-Meyer theoretical distribution for spruce and beech are indicative of well formed selection structure. Compound stand structure, vertical and step like density (Fig. 2) and wide age range indicate on its many storied and all-generation character. Composition and amount of natural reproduction is not an evidence of fir declining what is typical for Western Carpathians (Tab. 3). Advisable values of relative crown length and coefficient of slenderness show good conditions for tree growth and its high resistance from snow and wind activity irrespective of biosocial tree position (Tab. 4). Repeated observation on fixed investigated plot would enable to evaluate growth dynamics of selection stand which has been under strict protection for short time.
