The paper deals with the study of broad-leaved plants of the Southern Urals broad-leaved-conifer forests. Stationary studies were conducted on the territory of the South Ural state natural reserve, where 9 forest sites in different types of broad-leaved forests were laid. The research used standard methods while microclimatic observations used digital thermometers-recorders Thermochron. The authors have obtained some data on the structure and composition of the characteristic types of broad-leaved forests with oak and maple domination. The authors have classified ecosystems and plant communities, selected 3 types of biogeocenoses and 4 types of phytocoenoses. Studies have established that selected types of broad-leaved forests are associated to certain elements of relief and high-altitude levels. The obtained materials provide the basis for further monitoring of forests.
