Site description A clear, shallow, predominantly sandy bay with extensive seagrass beds; Qatif is on its west side and Dammam on the south. Local factors make the intertidal zone the richest in the Saudi Arabian sector of the Gulf: the bay is well-protected from winds and from water currents, allowing sedimentation of the finest particles, and a large nutrient input is provided by run-off from the Qatif oases and by organic waste effluent. The extensive intertidal flats of sand-mud and mud were formerly fringed by extensive mangrove and saltmarshes, but much of these have now been destroyed by land-claim. The bay is an important nursery for shrimps and fish and sustains several traditional fishing communities. It contains one of the largest oil facilities in the world and includes several important archaeological sites.
