Abstract


The per-stratum database of Ukrainian State Project Forest Management Production Assossiation "Ukrderzhlisproekt" is studied and analyzed. General level of distribution and productivity of Weymouth pine (Pinus strobus L.) in Ukraine is under research. In Ukraine forest stands, where Weymouth pine is a prevailing species, occupy the area of 165.6 ha. Plantations, where Weymouth pine is a secondary species, are common in the area of 2,542 ha. The distribution of Weymouth pine plantations is studied according to their origin, density, growth class, age class and types of vegetation conditions. Weymouth pine is defined as a promising type to be introduced in most of the regions of Ukraine.
