Pogribnyy O. Forestry-ecological aspects of the Scotch pine (Рinus sylvestris L.) forest stand formation in Ukrainian Carpathians.

Object of research - forest stand formation of the Scotch pine (Рinus sylvestris L.) in Ukrainian Carpathians. Purpose of research - the forestry-typological, dimensional, and specific structure of the root type's forests formation with the Scotch pine should be established and justified, biological properties should be determined and ecological conditions of their distribution, formation and reproduction at Ukrainian Carpathians should be set. Methods of research: forestry-taxation - for placing permanent plots and defining taxation structure of the timber stands; phytocenosis - for defining phytocenosis structure of association; forestry-crops - for defining sowing properties seeds; morphological and anatomical - for estimating morphological variability of cones; mathematics and statistics - for processing mathematical data and for modeling statistical dependencies. Scientific novelty - plastid pigment content in the Scotch pine needle in the different types of forest has been defined, the tree electro-physiological indicators, their connection to the sanitary state and types of forest have been estimated and Scotch pine biological hardiness has been identified, resin productivity on the territory of Ukrainian Carpathians has been determined. Has been verified that forest stands of the Scotch pine tree had been nominal primary forest that has six phases of development with cycle of development 245-275 years. Profile of the main types of the forest has been placed, on which seven different types of forest has been discovered and mechanism of it change due to the angle of inclination and exposition of the slope has been determined. The typical compound of the Scotch pine trees basidial pilete macromycete in the basic types of forest has been studied. The influence of the microclimatic conditions of the rock scattering of the different slope exposition in Ukrainian Carpathians on the Scotch pine trees forest stand dispersal and development has been examined. The influence of the illuminated territory under forest stand on the process of the Scotch pine trees recovery has been investigated. Practical value of the research. Practical value of the scientific result of the dissertation lies in recommendation processing which are directed on: maximal restriction of relict Scotch pine forest stand access by common people and tourists by changing directions of the touristic routs; harvesting of the local seed material of the relict Scotch pine trees for forestry-crop; adding to the classification of the existing Scotch pine trees forests types in Ukrainian Carpathians as: А2-С; А5-С; В5-С. Area of application: forestry.
