The species composition of grass and subshrub layer of basic forest phytocenoses in the north-eastern part of Ukraine is analyzed. Six classes of forest vegetation are identified according to the ecological-floristic classification in the studied region. A revision of plant species characteristics is made for them. It is found that typical plants of grass and subshrub layer are characterized by broad ecological amplitudes with respect to the main environmental factors (temperature, humidity, continentality). On the basis of data on individual ecological optimum of plant, one can expect the growth in the share of hydrophilic and thermophilic species along with the corresponding decrease in xerophilous and boreal plant species in grass and subshrub layer of forest ecosystems in the north-eastern part of Ukraine.
