Laguna de Olomega. Designation date:02/02/10; 7,557 ha; 13°19'N 088°04'W. Located in the Central American Dry Forest ecoregion, the Olomega Lake is the largest body of freshwater in eastern El Salvador. The site also covers the surrounding vegetation, such as the herb-dominated marshes and a patch of seasonally saturated forest, known as La Chiricana and one of the last relicts of this community type in the country. Within it the mangle dulce (Bravaisia integérrima), a very rare species in El Salvador, is abundant. The site harbors threatened species, e.g., Muscovy Duck (Cairina moschata), Glossy Ibis (Plegadis falcinellus), Limpkin (Aramus guarauna) and the treefrog (Plectrohyla guatemalensis), and is a feeding and staging area for several migratory bird species (e.g., Lesser Scaup (Aythya affinis), Blue-winged Teal (Anas discors), etc). The site plays a major role in flood control, water purification and groundwater replenishment that will be later used, by wells, by the local population (ca. 9,000 inhabitants). The main threats are water pollution, deforestation, cattle farming, overfishing and exotic invasive species, such as Water Hyacinth (Eichornia crassipes). Laguna de Olomega and the nearby El Jocotal (Ramsar site N° 970) are located within the same watershed. Ramsar site no. 1899. Most recent RIS information: 2009.
