Comunidades arbustivas seriales en el Andévalo y Sierra de Aracena (Huelva; SO España)

Abstract

A study about the serial shrub communities has been carried out for the Andevalo and Sierra de Aracena zones in Huelva, analyzing their variability and distribution in the area. 14 associations has been found: Genisto hirsutae-Cistetum ladaniferi, Ulici eriocladi-Cistetum ladaniferi, Phlomido purpureae-Cistetum albidi, Scillo maritimae-Lavanduletum pedunculatae, Erico australis-Cistetum populifolii, Halimio ocymoidis-Ericetum umbellatae, Ulici eriocladi-Ericetum umbellatae, Retamo sphaerocarpae-Cytisetum bourgaei, Genistetum polyanthi, Asparago albi-Rhamnetum oleoidis, Phlomido purpureae-Juniperetum turbinatae, Hyacinthoido hispanicaeQuercetum cocciferae, Phillyreo angustifoliae-Arbutetum unedonis and Senecioni lopezii-Quercetum lusitanicae, and one more community belonging to Genistion fl oridae Alliance, with no association category is located. According to the distribution of these communities, to their situation in the vegetation series and using recent bioclimate data, an ecological landscaping outline for the distribution of the vegetation series is proposed in the area, recognizing the next ones: Myrto communis-Querceto rotundifoliae S., Pyro bourgaeanae-Querceto rotundifoliae S., Sanguisorbo agrimonioidis-Querceto suberis S. and Arbuto unedonis-Querceto pyrenaicae S.
