Abstract
The spatial structure of the fir undergrowth vs. to the fir, aspen, and birch trees in the climax community of the fir-aspen-birch forest was analyzed by the method of R-functions. The analysis showed that the fir undergrowth is primarily concentrated near old fir trees, but near the fir stumps it is more rare than expected. This distribution of the fir undergrowth should have resulted in the decrease in area and number of fir population. The fir undergrowth concentrates the most near the small-leaved species, where dense fir clumps are formed. The populations of the small-leaved species are a stabilizing factor of the dominant population in the fir-aspen-birch forests.
