Statistically significant transcontinental changes of biomass, net primary production (NPP) and specific primary production (SNPP) of all wood fractions and understory layer of larch forests on the territory from the United Kingdom to the Japan and South of China, using data of 540 sample plots with the definitions of phytomass and 116 plots with the definitions of NPP and phytomass are stated. Larch forests of Eurasia have substantial regional differences on biomass, NPP and SNPP, which are largely determined by climate peculiarities.
