Abstract
A biogeographical and trophic analysis on Nardus grasslands from the Central Range has been done based on the floristic composition. Previous phytosociological studies on published data and own data show twelve associations in the studied área included into Campanulo herminii-Nardion strictae alliance. This community diversity is related to biogeographic and bioclimatic gradients, as well as edaphic and topographic characteristics. Results showed that most orophilous Nardus grasslands are the richest communities on Western-Mediterranean endemics and community diversity is adjusted to a biogeographical pattern in the Central System. On the other hand, differences on trophic valúes for bioclimatic belts (thermotypes) and biogeographic units were not relevant.
