Site description (2001 baseline)
This site is situated around the town of En Nahud, south-west of El Obeid. It is an area of old fixed red sand-dunes (‘goz’ soil), vegetated principally with shrubs and scattered trees in which Acacia senegal is dominant. The limits of this habitat are clearly defined by an abrupt change in soil-type and an accompanying change in vegetation; Acacia senegal disappears and Dalbergia melanoxylon becomes common. Although the limits of the IBA remain undefined, it includes the area west and south of En Nahud to Ghubeish and El Odaiya, and east towards El Obeid.

Key biodiversity
See Box and Table 2 for key species. Flocks of up to, and sometimes exceeding, 100 Falco naumanni overwinter; the species is particularly abundant in years when tree locusts Anacridium spp., which feed almost exclusively on Acacia senegal, are common. Circus macrourus also winters commonly in the area. Of particular interest is Mirafra cordofanica, a Sahel biome species which is restricted to grassy openings in bushy areas on ‘goz’ soil. It is one of the commonest birds in the area. One species characteristic of the Sahara–Sindian biome (A02) and three of the Sudan–Guinea Savanna biome (A04) have also been recorded (see Table 2).
