Zones humides de l'oued El Maleh. 15/01/05; Mohammedia; 1,200 ha, 33°39'N 007°23'W. Site of Biological and Ecological Interest. A wetland complex made up of two separate systems: a littoral swamp and salt steppe which correspond to the estuary of the Al Maleh River, and a small reservoir situated 30km upstream. This site is an important refuge during migrations and for wintering for a variety of 80 bird species, ranging from waterbirds to sparrows and birds of prey. The dam has been crucial in promoting the development of agriculture and fishing in the region, which are the main activities carried out, in addition to playing an important role in the control of floods. Its water volume has been reduced, however, due to sedimentation and this, combined with the canalization in parts of the estuary of the river, has meant that many floods still have destructive effects. The estuary of the Al Maleh is also used for educational purposes for schoolchildren from the nearby city of Mohammedia in order to raise awareness of environmental protection. Pollution by several industries (chemical, mechanical and electrical) which surround the site poses the main threat, together with the construction of canals which have altered the site's hydrology. Ramsar site no. 1486. Most recent RIS information: 2005.
