Contributo alla conoscenza dei boschi a Laurus nobilis L. della Sardegna, habitat prioritario ai sensi della Direttiva 92/43/CEE

Contribution to the knowledge of the Sardinian Laurus nobilis L. stands, a priority habitat of the 92/43/EEC Directive . The results of the phytosociological study of the Sardinian Laurus nobilis L. stands are here presented. The statistical analysis of the surveys, carried out on the best known populations, allowed us to recognize four new plant communities, referred to one association and three subassociations. In Sardinia the Laurus nobilis L. stands are present on effusive and metamorphic substrata, on typic xerorthent or lithic xerorthent soils, in the oceanic pluviseasonal Mediterranean bioclimate. The investigated stands show a good conservation status and high recruitment levels, in relation to the high naturalness of the ravines and valleys in which they occur.
