A research object is the beech forests of central part of Western Podillya hill area. Goal of work - to discover forest-ecological and phytocenotic features of forming beech forest stands and influence of different methods of cuttings on development there the young generation of the forest, to work out conceptual principles of preservation and reproduction of gene pool of trees of European beech basing on principles of nature oriented forestry. Research methods - forest-inventory, comparative ecology, geobotanic, agro-chemichal, spectrophotometry, math-statistical. Scientific novelty. First on territory of central part Western Podillya hills area the respondent has investigated structure and dynamics of natural renewal of European beech and it's companions, peculiarities of grass cover development and forest young generation forming, as a result of main use cutting: forest clear cutting, narrow forest strip clear cutting, gradual two-, three- stages cutting, Vagner narrow strip cutting, cavity in three stage cutting, group selective in three stage cutting, nest-selective and voluntary-selective, and voluntariy selective of strong intensity and cuttings by improving quality composition of forests: pass cutting and cutting of re-forming. It is set that most intensively natural seminal renewal of valuable breeds is on the cutting areas of even gradual two-stage, voluntary selective of strong intensity and group-selective of three-stage cutting. The experimentally confirmed system of optimum age-old and phytocoenotic parameters of changing on selective forms of management in the beech forests of Western Podillya Hill area, which foresees the holding different forestry activities: care cutting, re-forming cutting, stimulation of reproductive processes, selection of "trees of the future", diminishing of tension of unfavourable for growth and development of undergrowth of ecological and phytocoenotic factors already in middleage and almost riped trees. Results: author's proposition were used during first stage of re-forming cuttings in State Forestry "Bibrky Forestry" and "Stryy Forestry", and also for working out "Ways of cuttings of different methods of system of gradual, selective and combined cuttings in forests of Lviv regional management of forestry and game management", ratified by Derzhkomlisgosp (State Forestry Committee) of Ukraine of 10.07.2006 and "Temporal regulation about the conduction of re-forming cuttings in the forests of the Lviv regional Directorate of Forestry and Game Management", approved by forest expedition and State Administration of Environment and Natural Resources Protection in the Lviv area and ratified by the Lviv Regional Administration of Forestry and Game Management of Derzhkomlisgosp of Ukraine of 02.09.2008. Sphere of Industrial use: Forestry.
