Spatial distribution of landscape types and dominant tree species over the study region. The map depicts the spatial distribution of landscape types over the study region through colorscheme. Boundaries of the landscape zones are provided by the Ecological Atlas of Russia (2002). The locations of sites, where the field observations were conducted are marked with symbols, which type reflect the dominant tree species for that site
