Site description The head of a 10-km-long tidal creek which penetrates 7 km inland from the Gulf through Dubai city, containing tidal mudflats (maximum low-water extent c.150 ha) and a lagoon with maximum depth of 2 m and tidal range of 1.0-1.5 m. Flat sabkhah surrounds the intertidal area; there is some salt-tolerant scrub above the high-tide line, and some Tamarix in disturbed areas. The intertidal zone supports an abundant invertebrate fauna, but in late 1993 most of the 50-cm-deep top layer of mud was scoured off and a network of channels created, after which most of the area was densely planted with mangrove saplings. There is nutrient enrichment from irrigation run-off and treated sewage effluent. Seawards of the mudflats the creek has been dredged for shipping, and much is bounded by commercial development. The land is under the authority of the Coastguard, but is owned by the Government of Dubai/His Highness Sheikh Mohammed.
Key Biodiversity See box for key species. The most important mudflat area in the UAE, supporting a more varied assemblage of waterbird species at much higher densities than any other sites in the coastal zone, especially in winter and during passage periods. Especially important for Limicola falcinellus; no other significant concentrations have been found elsewhere in the country. The site is well-known for its population of Phoenicopterus ruber, which is present all year but is largest in winter (January av. max. 1,400, 1989–1992; peak 2,300 in February 1990); another notable winter visitor is Pluvialis fulva (max. 40). Large numbers of Larus ridibundus roost in winter (see box).
