Excluded are the formations situated within the northern, non-Alpigenous, area of natural lowland occurrence of Picea abies, dominated by northern forms of Pinus sylvestris ssp. sylvestris (Pinus sylvestris var. septentrionalis, Pinus sylvestris var. rigensis, Pinus sylvestris var. borealis, Pinus sylvestris var. rossica), and those dominated by Pinus sylvestris ssp. lapponica or by Pinus sylvestris ssp. sibirica, all of which are treated as constituents of the taiga and its transitions to the nemoral and steppe zones, and are listed under units 42.C and 42.D.
