Site description The site lies about 30 km south-west of the coastal town of Mostaganem (just to the east of Oran) and c.60 km north-west of Dayette Morsli–Plaine de Remila (site DZ016). It consists of the flood-plain and marshland system of several oueds that spread across the Plain of Habra before discharging into the Mediterranean Sea to the north (via the River La Macta). Three major oueds flow into the flood-plain from the south and two of these, the Oued Sig and the Oued l’Habra, flow all year-round. The site is roughly triangular in shape and is bounded to the south, west and east by hills. It consists of open water, marsh, humid steppe and ‘sansouires’ (saltmarsh) very similar to those of southern France, but rare in North Africa.To the north, the flood-plain is separated from the sea by a dune system, through which flows the River La Macta; there is also an old river channel which runs west behind the dunes and permanently contains water and beds of Phragmites sp. The site consists of large areas of shallow, open water and permanent marsh, with other areas of temporary inundation following rainfall. The salinity is extremely variable, but can be very high, especially at the seaward end. Large parts of the site can be dry from July to October, while the permanent marsh and other areas of open water are replenished year-round by the inflowing oueds. Scirpus maritimus and Juncus subulatus dominate the northern part of the marshland and other emergents throughout the marsh include S. lacustris, S. littoralis, Juncus acutus and Phragmites communis. There is heavy grazing by goats, cattle and sheep, which restricts P. communis to the edges of open water areas and drainage channels. Flooded areas show scattered growth of Potamogeton pectinatus, Ruppia maritima, Zannichellia palustris, Enteromorpha sp. and filamentous algae. The southern end consists of Salicornia sp. steppe, with clumps of Tamarix sp. in the south and east. On the northern, dune area there is Sarcocornia fruticosa and Juncus acutus, with bushes of Arthrocnemum glaucum and Tamarix gallica. The site is surrounded by irrigated agriculture and there is heavy grazing pressure and some hunting.
