Characteristics of the forest vegetation of Biloozersky National Nature Park (Ukraine)

Abstract

The article presents the results of study on Biloozersky National Nature Park’s forest vegetation, which occupies 92,4 % of the Park’s territory. The classification of the forest vegetation is made based on the dominant system. The forest vegetation is represented by the communities of the formations Pineta sylvestris, Querceta roboris, Alneta glutinosae, Betuleta pendulae, and Populeta tremulae. The area is dominated by pine forests (about 70 %); there are significantly less oak-pine and oak forests. The pine forests with green mosses are the most common. In similar environmental conditions, but on more fertile soils the association Pinetum (sylvestris) convallariosum (majalis) occurs often. The communities of the association Quercetо (roboris)–Pineta sylvestris, occupy significant areas; they are formed on the straightened plots and the bottoms of slopes. The communities of the formation Quercetа roboris occupy small territories and are confined to the second sandy terrace of the Dnieper. In oak forests the fragments of vernal ephemeroid synusiae occur with Scilla bifolia, Corydalis solida, and the rare for the region boreal species Pyrola minor and Chimaphila umbellata. The derivate communities of Populeta tremulae have been formed on the old pine clearings. The communities of this formation occur on small areas sporadically throughout the Park. The waterlogged ecotopes in the floodplains of the Bile Lake have small areas of Alneta glutinosae.
