Covering over 14,500 hectares, Bul Syayeef is the United Arab Emirates' sixth Ramsar Site. It is located in the west of Musaffah channel, about 20 kilometres outside Abu Dhabi City.
The international importance of the Site (Site no. 2293) is due to its highly diverse wetland habitats including mangroves, salt marshes and seagrass beds, and the large number of species which they host. Its tidal mudflats are home to over 80 migratory and resident birds. In 2009, it hosted one of the largest breeding events of the greater flamingo (Phoenicopterus roseus), with a record of 2,000 breeding pairs and 801 hatchlings. The Site also supports globally threatened species such as the critically endangered hawksbill turtle (Eretmochelys imbricata) and the endangered green turtle (Chelonia mydas). The greater spotted eagle (Aquila clanga), the Socotra cormorant (Phalacrocorax nigrogularis) and the dugong (Dugong dugon) are all classed as vulnerable.
Potential threats within and around the Site are related to the growth of housing and commercial and industrial areas, transportation and fishing activities.
