This site is located c.15 km inland from the Red Sea, immediately east of the Red Sea Hills, c.25 km north-west of Port Sudan. The focus of the site is a 500-m-wide riverbed in which a water-pumping station has been built to provide water to Port Sudan. The pumping station is located on what has become an artificial island, surrounded by the only permanent water in the Red Sea Hills. There is a small garden on the island, with lemon and guava trees and date-palms, which provide the only concentrated green vegetation in a large area during the dry season. The site includes an area of the surrounding desert which, apart from a few scattered bushes along the riverbed, is largely barren.
See Box and Table 2 for key species. In addition, the site is an extremely important focus for a wide diversity of migrant Palearctic passerines during August–October, with estimates of up to 10,000 Acrocephalus palustris being seen in a single day. Other species recorded, albeit in much smaller numbers, include Crex crex, Acrocephalus griseldis and Emberiza cineracea.
