We studied of the natural forests structure in the Zauralsky hilly piedmont province (Middle Urals). Different moistening conditions (fresh, occasionally dry; stable-fresh; fresh, occasionally wet; wet, wet occasionally) are presented in the ecological profile. Complex forest geobotanical researches were carried out. Full profile soil cuts were put. The characteristic of 12 types of the natural forests vegetation, morphology, physical and chemical properties of soils was given. We determined the position of forest types Zauralskaya hilly piedmont province, was selected on the basis of principles of genetic typology, in the classification scheme developed according to «International code of the phytosociological nomenclature». We revealed that the great value for the formation of specific structure of the forests has ecotone effect. Forest types were formed at the junction of the two subzonal groups of vegetation: boreal forest of taiga types of the class Vaccinio-Piceetea and gemiboreal light-coniferous herbal forests of the class Brachypodio Pinnati-Betuletea. In the waterlogged conditions the species structure was influenced by intrazonal not wood types of vegetation: swamps and water meadows. The landscapes diversity, the moisture regime, soils and complex ecotone effect resulted in a high diversity of forest types and their specific structure.
