Evidence of riverside ash tree forests in southern Galicia (northwestern Spain)

Abstract

The paper provides phytosociological data to support the occurrence of ash or ash and elm riverside forests in the southern half of Galicia. As a result of its particular floristic composition (clearly related to the Fraxino Ulmenion minoris suballiance), a new community, to be called Hedero hibernicae-Fraxinetum angustifoliae, is proposed. This forest community, typified at association level, shows a territorial distribution usually associated with temperate sub-Mediterranean or clearly meso-Mediterranean areas of Galicia.
