Abstract

Directional changes of vegetation in a wet meadow complex are described, comparing phytosociological releves taken in 1956, 1963, 1984 and 1989, and vegetation maps made in 1956 and 1984. The releves were located at various distances from the pond shore predominantly reflecting differences in water regime and intensity of farming. The data were elaborated using direct and indirect gradient analyses. Alterations of environmental factors (moisture, nitrogen) were expressed using Ellenberg's indicator values.
