Floristic diversity and economic value of permanent grasslands in the For river valley

摘要

The agricultural value of fodder from floristically diversified permanent grasslands in the river For valley (south-eastern Poland) was evaluated. Phytosociological assessment by means of Braun-Blanquet's method was performed on meadows and pastures.In total, 502 phytosciological records were made, among which 23 communities belonging to the following classes: Phragmitetea, Scheuchzerio-Caricetea nigrae, Molinio-Arrhenatheretea and Plantaginetea maioris, were distinguished. The grasslands yielded ata fairly low level and their economic value was differentiated (UVN from 0.1 up to 9.0).
