The potential ecological ranges of two forest forming species of light coniferous forests are studied in the light of the soil ecology data for Pinus sylvestris L., Larix sibirica Ledeb. L. gmelinii (Rupr.) Rupr. and geography of suitability of soils for forest growth in Central Siberia. It is found out that about 80% of the analyzed territory of Central Siberia is suitable for larch and pine by soil conditions. Pine and larch forests currently occupy about 12 and 32% of the potentially suitable soils of the region, respectively. The specifics of distribution of the current larch and pine forests on soils with different forest suitability is noticed and the role of soil and climatic factors in distribution of light coniferous species is assessed.
