Title Floristic biodiversity of the High elevation wet grasslands: case of some Moroccan High Atlas sites
Author Safia ALAOUI HARONI, Mohamed ALIFRIQUI, Ahmed OUHAMMOU
Abstract In the High Atlas mountains, the wet grasslands and pozzines constitute a highly coveted pastoral resource. Its flora is characterized by a great specific richness: 165 taxa are recorded in the study area (Oukaimeden plateau, Tichka plateau and the upstream of the Ait Mizane high valley) and schow a rate of endemism estimated at 30.3% and a degree of rarity reaching 31%. In a Mediterranean context, the wet grasslands flora is supplemented with plants of northern origin 15.7%, pushed towards the extreme southern latitudes during the last glaciations. These wet pastures, highly sensitive by their structure, ecological functions
and their conservation state, are very affected by the climatic changes and the global environmental changes.
