FOREST COVER PERCENT AND SILVICULTURAL AND MENSURATION PECULIARITIES OF THE STANDS IN THE RIVER CATCHMENTS IN THE LEFT-BANK FOREST STEPPE

Abstract

The results of investigations of actual and water protection forests coverage on the river catchments within the Left-Bank Forest-Steppe zone in Ukraine are presented. In the catchment areas of the Sula, Psel, Vorskla, Siversky Donets river, tree stands were distributed by the age groups, relative density, site classes, forest categories based on the data from the electronic database of “Ukrderzhlisproekt” Production Association. The percentages of natural and planted pine stands were determined in the fresh oak-pine fairly infertile site type and of oak stands, in fresh maple-lime fertile oak forest type. The productivity for natural and planted oak stands were analyzed in fresh maple-lime fertile oak forest type as well as for planted pine stands in fresh fairly infertile oak-pine site type.
