The coastal plant communities of Juniperus macrocarpa in the Mediterranean region

Abstract

Juniperus macrocarpa is a threatened taxon growing on coastal areas of the Mediterranean region. A remarkable part of its communities are included in Juniperion turbinatae, considered as priority habitats for conservation in the Habitats Directive 92/43 EEC. We have summarized the current status of this type of vegetation, including the described associations of this alliance in order to analyse the variability of the syntaxa, based on its floristic composition and geographic distribution. The available relevés were arranged in a synthetic table and subjected to a detendred correspondence analysis. Two new suballiances (Juniperenion turbinatae and Asparago orientalis-Juniperenion macrocarpae) have been proposed. A typological classification of these communities with ecological and biogeographical diagnoses is given.
