На тлі загальної континуальности структури рослинному покриву, відповідно до ландшафтної структури, властива чітка макро- і мезо- дискретність. Вона зумовлена особливостями геолого-геоморфологічної будови, висотно-кліматичними чинниками .
On the background of the general continuity of structure of a vegetative cover of
mountain landscapes local discontinuous climatic, edaphically, an external mechanical and age origin is also peculiar. Significant continuum peculiar in conditions damp and fertile soils to Abies-Fagus-Qercus forests on Pre-Carpathians heights, to Picea-Abies-Fagus forests on low mountains, and also to Alnus-Qercus forests on plains. In specific ecological conditions discretization of forests communities as significant competitive advantage there are peculiar only for the limited quantity of species is distinctly shown.
