Rodriguez Guitian, M.A., Romero Franco, R. & Ramil Rego P. Caracterizacion ecologica y floristica de las comunidades lauroides del occidente de la Cornisa Cantabrica (Noroeste iberico). Lazaroa 28:35-65 (2007). Mediante la comparacion de los inventarios floristicos obtenidos en los territorios Galaico-Asturianos occidentales (Sector GalaicoAsturiano, Subprovincia Cantabro-Atlantica, Provincia Atlantica Europea) con los de las asociaciones vegetales previamente descritas en el ambito cantabro-atlantico iberico, se establece la presencia en el extremo occidental de la Cornisa Cantabrica de cuatro asociaciones vegetales dominadas por especies lauroides (Laurus nobilis, Arbutus unedo, Rhamnus alaternus): lauredales costeros (Calluno vulgaris-Lauretum nobilis), lauredales interiores calcicolas (Tamo communis-Lauretum nobilis), lauredales interiores silicicolas (Holco mollis-Lauretum nobilis), y madronales (Frangulo alni-Arbutetum unedonis), asi como fragmentos de otra comunidad silicicola dominada por Rhamnus alaternus. Finalmente se realizan diversos comentarios sobre el significado biogeografico, valor paleoambiental e interes para la conservacion de las comunidades vegetales aqui tratadas.

Ecological and floristic characterisation of the lauroid communities of the western Cantabrian range (NW Iberia). Lazaroa 28: 35-65 (2007). The floristic composition of plant communities dominated by lauroid species (Laurus nobilis, Arbutus unedo, Rhamnus alaternus) existing in western Galician-Asturian territories (Galician-Asturian Sector, Cantabrian-Atlantic Subprovince, Atlantic-European Province) is revised. After comparison with other previously described communities, we conclude the existence of four associations, three of them dominated by laurel tree: Laurus nobilis, i.e. Calluno vulgaris-Lauretum nobilis on shelte siliceous cliffs, Tamo communis-Lauretum nobilis growing on lime rocky spurs in inland territories, and Holco mollis-Lauretum nobilis in siliceous territories, and a fourth association dominated by the strawberry tree, Arbutus unedo: Frangulo alni-Arbutetum unedonis. In addition, some comments are made on another shrubby, insufficiently known community dominated by Rhamnus alaternus. Finally, some remarks on their biogeographical and paleoenvironmental significance as well as the interest for conservation of these communities are also mentioned. Key words: Phytosociology, laurel tree communities, Laurus nobilis, strawberry tree, Cantabrian range, Spain.
INTRODUCCION Las especies lenosas plano-perennifolias (Lauraceae, Ficus, Buxaceae, Olea, Ilex, Quercus tp. ilex) constituyeron una parte fundamental de la flora que domino amplios territorios del occidente del continente europeo y [...]
