Abstract

First transcontinental changes in fractional composition of sample tree biomass of larches (Larix Mill.) and two-needled pines (subgenus Pinus) are reported, taking into account their regional differences by age, tree height, stem diameter, and volume, as well as tree density. All components of the tree biomass of larches and pines monotonically increases from the North to the South. Dynamics of pine biomass in the direction from the Atlantic and Pacific coasts to the continentality pole in Siberia is characterized by monotonous decrease of all components, including the roots. The latter is in contradiction with the change of the larch root biomass across the same gradient of climate continentality, which, unlike the mass of pine roots, is not reduced, but increased. The system of the transcontinental dependencies obtained allows its use in estimating forest biomass based on the local data of a tree enumeration per ha.
