To reveal the interspecific and regional differences of five-needle pines’ phytomass, a database has been compiled. It includes the phytomass indices of Pinus sibirica Du Tour, P. koraiensis S. et Z. and P. pumila (Pall.) Regel) in their natural habitats in Eastern Eurasia, namely 111, 47 and 35 determinations. Using the method of binary and block dummy variables, phytomass yield tables for Pinus sibirica and P. koraiensis valid within their natural habitats, and similar tables for P. pumila, separately for the Far Eastern taiga, Transbaikalian southern taiga and broadleaf forest subzone of Japan, have been compiled. It is found that the average height of the Pinus sibirica forests compared to P. koraiensis is higher by 11%, the stand density, on the other hand, is less by 13%, and stem wood volume is greater by 33%. Stem phytomass of Pinus sibirica, all other things being equal, is greater than that of P. koraiensis, and crown phytomass is less. In general, the differences of both aboveground and total phytomass (t/ha) in Pinus sibirica and P. koraiensis forests are virtually non-existent. Growing of P. pumila forest phytomass occurs in all investigated age intervals from 20 to 180 years. Understorey phytomass (including grass vegetation, shrubs and undergrowth) of P. pumila thickets decreases with the age. The total phytomass of P. pumila forests increases according to zonal gradient as following: the northern taiga of the Far East, southern Taiga of the Transbaikalia, and Japanese subtropics, amounting to 33, 38 and 145 t/ha respectively.
