Site description This site lies in the flood-plain of the Oued El Kebir and the Oued Bou Namoussa, just to the west of Lac des Oiseaux (site DZ005). It is the second-largest remaining freshwater marsh in Algeria, exceeded in size only by Marais de la Macta (site DZ017) and in winter the area of flooding and emergent vegetation is greater than that in La Macta. The marsh lies just above sea-level and is separated from the sea to the north by a sand-dune system through which the Oued Mafragh flows north into the sea. Water flows into the marsh from the east via the Oued El Kebir and from the south via the Oued Bou Namoussa and Oued Chourka Garaet. There is seasonal pattern of winter flooding and gradual drying out, with the marsh dry for at least three months between June and November. The water-level is usually less than 1 m and does not normally exceed 2 m. There is open water at the edge of the marsh, where it is grazed by cattle, and this extends into the middle in some places, but c.90% of the area is covered by emergent vegetation, dominated by Scirpus littoralis, S. lacustris, S. maritimus and Juncus sp. Phragmites communis is also widespread and Typha angustifolia, Glyceria fluitans, Carex sp. and Alisma plantago-aquatica also occur, as well as a national rarity, Butomus umbellatus. Submerged vegetation includes abundant Myriophyllum sp., Chara sp., Nitella sp., Ruppia sp., Callitriche sp., Zanichellia palustris and Ranunculus sp. There are scattered Tamarix sp. and Lemna minor. At the northern end of the marsh there is a saline area with Salicornia sp. and, at the base of the dunes, a strip of Alnus forest. There is considerable disturbance on the marsh, caused by large numbers and a high frequency of hunters shooting wildfowl in the winter. There is some pasture and cultivation and heavy grazing by sheep and cattle around the periphery.
