Carici remotae-Fraxinetum excelsioris

This forest is dominated by Alnus glutinosa or Fraxinus excelsior. Its herb layer contains Cardamine amara, Carex remota and other species of springs and wet sites in forests. Most species in its herb layer are nutrient-demanding, while acidophilous species are largely absent. This community occurs in forested springs on slopes or on waterlogged sites along slowly moving brooks on valley bottoms. This vegetation is widespread across the Czech Republic, especially at mid-altitudes, but most of the stands are spatially restricted.
