Ostapchuk O. Agro-technological methods of forest renewal of English oak plantations on the southern part of the Right-Bank Forest-Steppe Zone of Ukraine.

Based on research conducted in hardwood stands the forestry value of agro-technological methods of forest renewal of English oak plantations on the southern part of the Right-Bank Forest-Steppe Zone of Ukraine is given. The mensuration of oak in forest plantations according to the methods of cultivation of the soil, mixing schemes of forest species and its density is also presented. The structure of oak forest stands and dynamics of its taxational characters depending on the method of its establishment are analyzed, grounded and experimentally proven advantages of plantations established by planting of oak acorns. Improved agro-technological techniques of establishment of English oak plantations on fresh cuttings and not forest areas, species composition of associate and shrub species for the usage in solid English oak plantations are selected, and gave reasons for unreasonableness of European spruce (Picea abies (L.) H.Karst) introduction in the plantations and also considered the possibility of European beech (Fagus sylvatica L.) introduction as associate species in oak stands in the researched region for the biodiversity increasing of woody species. The dynamics of forest live cover on the cuttings and under the canopy of oak plantations are analyzed, revealed the changes that occur in the structure of grass cover of southern oak stands depending to the composition, age and density of tree stands, made the comprehensive assessment of natural regeneration of the principal and related species and the dynamics of its preservation on the cuttings and under the canopy of the parent stand.
