Dynamics of the horizontal structure of the tree stand in a pristine herb–bilberry forest of the subzone of the middle tiaga in the Komi Republic

According to observations from 1987 to 2010 on a constant sampling plot, using spatial statistics, we have shown dynamics of the horizontal structure of all-aged stands of a pristine spruce herb–bilberry forest. We note that the trees forming it provide a continual change of generations and, therefore, random community structure and its spatial stability. We determined that small-leaved arboreal plants, which represent part of the tree stand, tend to grouping at distances from 4 m. It was discovered that the mutual arrangement of trees of different sizes and species do not differ from a random occurrence.
