abstract:
River valleys are characterized by extensive biodiversity resulting from the chemical properties of the water itself, diversified littoral surface features, and varied humidity of habitats. These elements caused increased flora and fauna richness in the valley, thus enhancing the high environmental values. The floral and phytosociological study was carried in 2003-2005 in the Warta river valley, on an area of 26 hectares between the villages of Santok and Stare Polichno. The flora and communities of the area were analysed in terms of environmental evaluation, and phonological and faunistic observations were made. As a result 142 plant species were identified (including 4 trees and 9 bushes) and classified them in 7 communities from 4 phytosociological classes. Such a diversity of species caused a significant differentiation in the environmental evaluation. For the flora, the values of environmental evaluation of habitats varied from low, through moderate, to high. In spite of the area having only slight variability of surface features, it included habitats varying from permanently bogged, through strongly wet, wet turning to bog, to moderately dry.
