Abstract

This paper reports a phytosociological study on Arrhenatherum bulbosum hay meadows in the main mountains of the Iberian Central Range (Spain). Multivariate techniques (Cluster analysis and DCA-ordination) were applied in the classification and ordination of relevé-units and species. Lithology, soil nutrient content and soil moisture were identified as the most important environmental gradients in determining their community diversity. A new association, Armerio segoviensis-Arrhenatheretum bulbosi, is proposed for this type of hay meadows. Lower ranking units, such as subassociations and ecological variants, explain the community diversity according to the ecological patterns revealed.
