Mandzyuk V. Forest ecological network of Holohory-Kremenets Hills.

The object of the research is wood natural systems of the Holohory-Kremenets Hills. The purpose is to identify forestry and ecological aspects of the structure and phytocenotic forest communities of the Holohory-Kremenets Hills and to develop scientific principles of the formation of the latitudinal corridor and the national environment network of specialized facilities within it. The methods of research are forestry-taksatic, biometric, floristic, ecological and phytocenotic, cartographic and mathematics and statistics. Scientific novelty. The features of the structure of the forest shelter- Holohory-Kremenets Hills. The influence of the hill landscape surface forms on the edaphotopic formation and composition of natural stands was first determined. It was ascertained that there are two age stages of the stands development and forest plant communities floral: to 60 years and after 60 years. On the first of these (polydominant) forest formed from many major forestforming and related species from typical broad - leaved shrub and grass species and on the second stage (narrowly dominant) it is formed with the insignificant admixture of the related species and typical and differential regional plant communities' species. The results are used to improve the regulatory framework and features of specialized forestry, aimed at fostering local ecological network, the general scheme which should be developed on the basis of spatial analysis of the valuable in the natural aspect forest sites distribution. Various trends of forest management within the different structural ecological network elements were substantiated and recommended. Branch of application: forestry.
