Abstract

Based on the generated database of 413 and 490 plots of biomass of Populus spp. and Betula
spp. in Eurasia, statistically significant changes in the structure of forest stand biomass were
found with shifts in January temperatures and average annual precipitation. When analyzing
harvest data, the propeller-shaped biomass patterns in the gradients of average annual precipitation
and average January temperatures are obtained, which are common for both deciduous
species. Correspondingly, Populus and Betula forests show a regularity common to
the biomass components: in the cold zones the precipitation increase leads to the increase of
biomass, and in the warm ones to their decrease. In wet areas, the increase of temperature
causes the decrease of biomass, and in dry areas, it causes their increase. In accordance with
the law of the limiting factor by Liebig-Shelford, it is shown that both an decrease in temperature
in dry conditions and a increase in precipitation in a warm climate lead to a decrease in
the biomass of trees.

Keywords
