Plant Diversity in Sardinian Mountain Rangelands: Analysis of Its Relationships with Grazing, Land Management, and Pastoral Value

In this study, we analyzed the effects of grazing on native and endemic plant diversity, as well its relationship with pastoral value along a gradient abiotic biotic factors types land management in mountainous area central-eastern Sardinia, Italy. Plant diversity was estimated by conducting floristic survey within plots. total, 231 species were recorded 63 plots distributed study area, total number included 20 species. Species richness mainly affected type management, soil attributes, altitude, bioclimate. Pastoral strongly nutrient availability Our results suggest that cover increases altitude. Finally, Sardinian rangelands, negative effect pressure observed.
