Site description The site lies about 250 km south of Constantine and c.80 km south of Biskra. It lies in the depression south of the Massif de l’Aurès (part of the Saharan Atlas) at the very northern fringe of the Sahara desert and is separated from the line of wetlands just south of Constantine (sites DZ010–DZ014 inclusive) by the Massif de l’Aurès. Chott Merouane et Oued Khrouf lies between the two roads leading south, the N48 to El Oued and the N3 to Touggourt and just south of the larger Chott Melrhir, from which it is separated by a strip of dry land about 4 km wide and by the N48 road. A series of small, seasonally flooded wetlands extends eastwards from Chott Melrhir into Tunisia. The northern part of Chott Merouane lies 40 m below sea-level. It is surrounded by arid steppe (sand and salt scrub) and is seasonally inundated, with the lowest parts remaining permanently flooded with saline water due to the outflow from Oued Khrouf. The inundated areas are fringed by Arthrocnemum, Limonium, Juncus, Salicornia, Sarcocornia, Scirpus and Suaeda spp. A shallow lake at the western edge of the site, which is fed by a spring and becomes contiguous with the inundated areas after heavy rain, contained filamentous algae and Potamogeton and Chara spp. in 1977. There is a small grove of date-palms to the north of the site, irrigated via a channel (containing filamentous algae and Phragmites communis) which leads from a small oasis at the northern end of the site. There is some hunting, but this appears to be largely confined to the strips of dry land adjoining the two main roads that run either side of the site. Other human activities include livestock-raising (mainly sheep), salt extraction and fishing.
