Site description Malaki Dam lies at 120-250 m on the edge of the Asir foothills, c.15 km east of Abu Arish. The reservoir, used for flood control and irrigation, is fed by the four major wadis of the extreme south-west of Saudi Arabia, with a catchment area extending well into Yemen. High rates of sedimentation have occurred in the reservoir, reducing its depth and expanding the water surface to c.10 km2 at high-water levels. To the north the reservoir is bordered by basaltic lava plains, and several rocky outcrops with hot springs are found on the south side and between the main wadis such as Ain Wakrah. There are a variety of marshy areas near the reservoir and in the lower runs of the four wadis, and huge banks of silt have isolated some permanent and semi-permanent pools from the main reservoir. Many of these banks are covered with Tamarix woodland edged by a lush growth of weeds and sedge. Similar vegetation borders the main wadis, while the wadi beds are cultivated with sorghum whenever the water level allows it. Some of the rocky outcrops are vegetated by palms Phoenix reclinata and Hyphaene, succulent Adenium obesum and the rare tree Acacia alba. Isolated Dobera trees, Acacia scrub and Salvadora bushes are the main vegetation on more open, sandy areas. Much of the surrounding hill area is grazed by livestock.
