Site description A large, shallow, saline lake at 1,480 m in the Shiraz basin of the southern Zagros. The lake is fed by the run-off from numerous small ephemeral wadis, by the Pul-i-Fasa stream in the west, and by numerous small springs around the shore, and covers 21,600 ha at maximum extent of flooding. Much the largest perennial springs are at Barmishur at the north-west corner and at Ab-e Paravan in the north, both creating pools c.2 m deep which overflow into extensive permanent marshes with Phragmites and Typha as well as feeding open marsh communities dominated by sedges, rushes and Chara. At maximum extent, the Barmishur marshes cover c.150 ha and Ab-e Paravan 250 ha. Water level varies widely with rainfall, and in prolonged droughts the entire lake dries out except for the pools at Barmishur and Ab-e Paravan. The lake shores support salt-tolerant plant communities dominated by Tamarix, Suaeda and Salicornia. The lake is bounded by limestone hills to the north and dry steppe to east and south. Land to the west (towards Shiraz) is largely under irrigated cultivation for rice, wheat, barley, melons, cotton and sugar beet. The lake is used for salt production and there are numerous large salt pans, particularly in the eastern portion. There is some livestock grazing and reed-cutting in the Barmishur and Ab-e Paravan marshes.
