Phytosociologic associations and Natura 2000 habitats of Portuguese coastal sand dunes

Abstract

The portuguese coastline is quite long and the littoral ecosystems are of the outmost importance in the context of the national flora and vegetation. The diversity of vegetation types and the endemicity of their flora justify the attention paid to coastal habitats in the implementation of the Natura 2000 network. In this paper we present a synatoxonomical revision of the phanerophytic, chamaephytic and hemicryptophytic communities occurring in the sandy coastal areas of Portugal, together with their correspondence to the “Natura 2000” natural habitat types. The production of synthetic tables with all available relevés has allowed the segregation of plant community types. We also include maps concerning the distribution of all validated vegetation types occurring in the portuguese sandy coastal areas.
