Abstract

"Temporary wetlands are small and shallow water bodies, which exist only in a part of the year. Despite their vulnerability, their presence is often favoured by traditional agro-pastoral activities. The flora is mainly composed of amphibious Mediterranean species, including numerous endemic and rare plants. The case study illustrates plant biodiversity of temporary wetlands in a protected area (Asinara National Park) and in a close unprotected one where traditional livestock activities are still practised. Different pond types, belts (inside the ponds) and communities were analyzed. Alpha (species richness and eveness), beta and gamma diversity were assessed for each of them. In addition, rare species or unique to an assemblage were listed. Comparison inside and between the areas and with the entire Sardinian gamma diversity were made in order to point out the conservation value of each assemblage and each area. Threats and possible mitigations were also identified. The results allow defining strategic conservation goals for temporary wetlands across the landscape as a whole."
