Site description A flat island, 12 km × 1 km, situated 2 km north-east of Umm al Quwain town, and mainly composed of low sand-dunes,saltflats, and some shallow hollows, with sparse salt-tolerant scrub. The sheltered inland side is much dissectedby tidal inlets, with associated mudflats; apart from some mangrove Avicenniai the island is tree-less. Tidal amplitude is 1 m. Khor al Beidah (site 005) lies opposite on the mainland.

Key Biodiversity See box for key species. The site is of global importance as one of the largest remaining colonies ofPhalacrocorax nigrogularis in the world; numbers fluctuate annually and the site has never beenaerially surveyed, so the cumulative breeding population over an entire season may be much higher.

Non-bird biodiversity: Mammals: gazelles Gazella have been introduced, and there are now c.50-100 on the island, mostly G. gazella (V) with some G. dorcas arabica (V).
