Abstract: Question: How is grazing intensity associated with speciesand morpho-functional traits (MFTs) composition, productiv-ity and richness of annual dominated grasslands? Have nativeand exotic species similar associations to this gradient? Location: Anthropogenic grassland in the Espinal vegetationin the sub-humid area of the mediterranean type climate regionof Chile (35°58' S, 72º17' W). Methods: Data were obtained from a long-term (eight years)experiment with six stocking rates (1 to 3.5 sheep/ha).Detrended Correspondence Analysis (DCA) and regressionanalysis were used to determinate the relationship betweengrazing intensity and biomass, richness, abundance and traitsof the species. Results: The first DCA axis was related to grazing intensityand explained most of the floristic variation (69.3%); theabundance of some non-native species,
