Description

As result of several field trips following doctoral research in Marianic-Monchiquensean Sector, we describe a new heathland named Lavandulo viridis-Ericetum lusitanici ass nova hoc loco (Genistion micrantho-anglicae, Rivas- Martínez 1979) as a thermomediterranean to lower mesomediterranean, upper dry to humid, schistose association. The analysis of 11 relevés, following Braun-Blanquet methodology shows the floristic identity of this new association as well as the chorological segregation of its area of occurrence. Finally, despite these communities already being relatively well known and although they are poor in species number, such heathlands show floristic singularity and own sinecology, with a large and distinct geographical area of distribution, so we emphasized its integration within Atlantic wet heaths priority habitat (⁄4020 – Annex B-I from Council Directive 92/43/EEC of 21 May 1992).
