Changes in forest ecosystems of the northern megaslope of the Carpathians

under the influence of transformation processes

Impact of transformation processes on current state of forest ecosystems have been researched

within model zones of forest areas of northern megaslope of Carpathians. Changes on forests resulting from natural and anthropogenic factors are analyzed. Impact of forest economy activities on age and spatial structure of fir-beech, spruce-beech, fur-spruce-beech and spruce-beech-fur forests and productivity of their native and derivative forest stands are reflected. The structure of those forests, specifics of their natural recovery and processes of re-afforestation of cropland and hays dropped out of economic use are characterized.

Keywords: forests, transformation processes in forests, forest economy activities, forestry taxation structure of forests, recovery of forests.

I.Ye. Kulchytskyy-Zhyhaylo UNFU Forming of rain floods flow from the small Carpathian catchment and its parts with different percentage of forest cover Forming of rainfall runoff from a small mountain catchment with area of 29.47 hectares and from located on it elementary catchments with different characteristics of forests in the beech-fir forests area in Ukrainian Carpathians was studied. During rainfall up 17 mm the difference between the maximum flow modules from elementary catchment (which is 95% covered by high completeness plantings) and catchment where these plantations are not at all (while 27% are non forest area) is 0.11 l/(s *ha). For these precipitation there is a difference between the formation of temporary runoff from elementary catchment with high completeness forests cover and elementary catchments where these plantations occupy no more than 40% of the area.

Keywords: rain runoff, flooding rain, columbine, stands.
