Site description This site lies some 12 km south of St Louis and about 60 km south-west of Djoudj wetlands (site SN001). The reserve consists of an extensive lagoon of variable salinity in a shallow depression, with a relict mangrove along the shores. The lagoon is replenished both by seasonal rainfall and by inflow of salt water from the Senegal river mouth and water-levels can be controlled artificially by means of a sluice gate. In addition to the official reserve, a number of brackish lagoons around the town of St Louis, all linked to the river estuary, are included in the IBA. These vary significantly in size, depending on the water-level in the Senegal river and the rainfall. The vegetation around the lagoons is Sahelian thorn-bush savanna dominated by Acacia spp. The lagoons are highly productive and those outside the reserve support important local fishing economies. The surrounding areas are used for livestock-grazing, agriculture and fuelwood-collection, all of which (together with fishing) are prohibited in the reserve itself.

Other biodiversity A project to reintroduce mammals and reptiles which were previously common in the Sahel region is based at Guembeul Avifaunal Reserve, where there is a captive-breeding enclosure for Gazella dama (EN), Oryx dammah (EW) and the tortoise Geochelone sulcata (VU). The plan is for reintroductions to be made in the northern Ferlo region (see Ferlo North, site SN007).
