Etang de Biguglia. 08/04/91; Corse; 1,790 ha; 42°36’00’’N 09°29’00’’E; Nature Reserve, Natura 2000 (SPA, SAC), Important Bird Area, Natural Area of Ecological Interest for Flora and Fauna. The Site is the largest coastal lagoon in Corsica, divided into two basins connected with the sea. It comprises shrub-dominated wetlands crossed by creeks within seasonally flooded agricultural land characterized by excavations and drainage channels. It is of international importance for the maintenance of biological diversity within the Mediterranean biogeographic region: it supports outstanding numbers of breeding and wintering waterbirds including grebes, cormorants, ducks, geese and swans as well as vulnerable reptile species such as Testudo hermanni and mammals such as Myotis capaccinii. Moreover, the coastal lagoon is an important spawning and nursery ground for critically endangered fish species such as Anguilla anguilla. The lagoon supports diverse and rare vegetation which varies from halophytic species and submerged vegetation fringed by reedbeds to maquis communities. The Site plays an important role in flood regulation and groundwater recharge. The main threats to its ecological character are illegal hunting and sedimentation. Human activities include tourism, fishing and agriculture. A management plan has been approved for the period 2014-2018. Ramsar Site no. 520. Most recent RIS information: 2014.
