A new winter deciduous forest and its associated Eurosiberian flora and vegetation in a Mediterranean mountain climatic refuge (Sierra Nevada, Spain)
Abstract
Sierra Nevada (south of the Iberian Peninsula) is an isolated mountain range (3481 m), a climatic and geographic island with vegetation refuges, including the Eurosiberian-type deciduous forest on its northern slope selected for this study. In this paper, we present the floristic and phytocoenological diversity, focusing on the deciduous forest, its associated vegetation and their value as protected habitats. We publish a new floristic catalogue with 440 taxa (19% of Sierra Nevada flora), of which 20 species are strictly endemic, 19 protected and 31 critically endangered. We publish also 75 new relevés recorded from all altitudinal ecosystems. We describe a new type of climatophilic forest (Poo nemoralis-Prunetum avium ass. nova), distinct from the only previously recognized biogeographically type Adenocarpo-Quercetum pyrenaicae, one hydrophytic mountain community (Montio fontanae-Ranunculetum omiophylli ass. nova) and two sub-associations and one community with Eurosiberian floristic influences (Genisto versicoloris-Juniperetum nanae rosetosum villosae subass. nova, Lonicero arboreae-Crataegetum granatensis ribetosum austroeuropaei subass. nova and Fraxinus excelsior community).
