Piceo abietis-Alnetum glutinosae

Photo on

This woodland is dominated by Alnus glutinosa or A. incana, while Picea abies is a constant accompanying species in the canopy. Its herb layer contains species of acidic soils, cool areas and springs. This association occurs along slowly running streams in submontane to montane areas. Peat forms on the soil surface. Many of the current stands originated through forest succession on abandoned, nutrient-poor wet meadows.
