Aim of the work: to determine the rate of plantations injuring by ice-crust, to research possibilities of natural rehabilitation of damaged plantations, to find ways for recovering of injured plantations. Method of research: examination of wood plantations with using of taxing notes of state forestry economies, bioecological analysis of wood plants and plantations, injured by ice-crust. Huge injury of plantations because of catastrophically ice-crust on the territory of Ukraine had place at first. Besides ecological and economical losses, there were also created favorable conditions for accumulation and spreading of fungi and bacteria infection and primary and secondary pest insects. It could create damage for injured and healthy wood plants. During cold cyclone plantations of pole to ripe age were damaged. Injuring of plantations had curtain disposition and depended on the strength and height of cyclone. Ripe and overripe trees of oak, that contain about 70 % of wood-cutting stock of the region, are characterized by low resistance to unfavorable environmental conditions. They are reservations for diseases, which in the near future may become centers of leaf and stem pest's reproduction. In conditions of intensive injuring of forests by ice-crust can cause ecological catastrophe and provoke the wave of mass drying up of damaged forests. Field of application - forestry.
