The paper presents the spatial, age and size structures of individuals in silver fir population. The studies were conducted in fir forest and Carpathian beechwood. It was found that fir trees were distributed randomly, whereas seedlings, new growth and up-growth had clumped distribution. The growth and development of individuals in aggregations and outside them were analysed. The stress was put on the impact of spatial structure on the process of population regeneration. Age pyramid was flat with its base very wide. About 40% of trees in the population were dead
