Italy designates Sardinian River Delta as Wetland of International Importance
08 juil. 2021
The Site comprises the final stretch of the Posada River, its alluvial plains, small side streams, oxbows and a sandy coastal lagoon. Typically for a river mouth with a gradient of fresh, brackish and salt water, there are Phragmites australis reedbeds, riparian tamarisk and willow communities and saltwater species such as glassworts (Sarcocornia spp.), seepweeds (Suaeda spp.) and sea purslane (Halimione portulacoides).
The Site’s network of waterways, temporary ponds and continuously shifting dunes provides a variety of breeding and wintering grounds for regionally and nationally protected animals including the European pond turtle (Emys orbicularis orbicularis), the common kingfisher (Alcedo atthis) and the little bittern (Ixobrychus minutus).
During floods the entire plain can become inundated, mitigating the upstream impact and distributing fertile soils along the alluvial plain. Some sheep and cattle graze within the Site, while orchards and horticultural crops are cultivated at its margins. During the summer months the coastal area is a popular tourist destination.
Italy has been a Contracting Party of the Convention on Wetlands since 1977 and has designated 56 sites onto Convention's the list of Wetlands of international Importance.
