Plugatar J. Condition of oak stands in Mountain Crimea and their regeneration

Object - structure and dynamics of taxation indices of seed and vegetative oak stands of Crimea. Aim - to study condition and productivity of oak stands in Mountain Crimea and to develop methods of reforming oak copices to seed stands. Methods - comparative ecology, common for forestry and statistics. Results - regularities of structure and condition changes for oak stands of Mountain Crimea. Level of resistance to unfavorable environmental agents level was estimated for two oak species (Quercus pubescens Willd. and Q. petraea Liebl.). Quantitative indices for oak understory of seed and vegetative origin have been determined in grud and sugrud conditions. Using index of ecological equilibrium disturbance three groups of area were distinguished in Mountain Crimea. Method for oak copices reforming to seed stands has been developed for forestry. Implementation - forest enterprises of Crimea. Branch of use - forestry.
