Kharku is a low, sandy, coral island with fringing reefs in the northern Persian Gulf, c.30 km off the mainland coast and 60 km north-west of Bushire. Surface water is lacking, but there is a freshwater well. Most of the island is covered in dune vegetation of grasses and low shrubs. It is fringed by a sandy beach with low vegetation. There are a few banyan trees near the south end of the island. The island was uninhabited until the late 1970s, when an airforce camp with a substantial landing stage and a number of permanent buildings was built at the north end. The nearby island of Khark (Kharg) is a major oil terminal.
See box for key species. An important site for breeding terns. Surveys in 1974 and 1977 indicated that c.5 pairs of Sterna bergii, 600 pairs of S. bengalensis, 2,500 pairs of S. repressa and 250-300 pairs of S. anaethetus were frequenting the island, but breeding success was minimal in both years because of egg-collecting by local fishermen.
