Habitat:
The Slender-horned Gazelle favours areas of dunes (ergs), other sandy substrates and interdunal depressions. It ranges widely in search of ephemeral vegetation (Beudels and Devillers 2013).
Range:
The known distribution is patchy. There are confirmed records from Algeria, Tunisia, Libya and Egypt, west of the Nile; there are some reports from Niger and Chad, but these are not supported by any hard evidence (Devillers et al. 2005, Beudels and Devillers 2013) and it is unclear whether the species ever occurred on the south side of the Sahara.
In the last 10 years, the Slender-horned Gazelle has been confirmed only in the Great Western Erg in Algeria, and the Great Eastern Erg, that stretches across the border between Algeria and Tunisia, extending into the Fezzan region of Libya. In Libya it was described a s very rare only reported from north of Zell in the west and close to the border with Egypt in the east (Hufnagl 1972). However, there are several recent examples of images posted by hunters on social media sites that show dead Slender-horned Gazelles reportedly killed in Libya. The species has disappeared from most of its former range in Egypt’s Western Desert (Saleh 2001, El Alqamy and Baha El Din 2006) and there are no confirmed records since about 2004. The latest records are from sites to the west of Siwa oasis, close to the border with Libya.

Conservation:
The species is known to occur in Djebil National Park (N.P.) and Senghar N.P. (Tunisia). In Egypt the species formerly occurred in Wadi El Raiyan Protected Area (P.A.) but is now extinct there. It may still be present in Siwa P.A. and White Desert P.A.
The total number of Slender-horned Gazelles in captivity is <100, with ca 78 in the USA and ca. 17 in Europe, all based on a small number of founders.
The species is listed on CITES Appendix I, CMS Appendix I.
Effective enforcement of bans on hunting, especially the protection of existing populations in protected areas (such as Djebil N.P. and Senghar N.P and possibly those of Siwa and White Desert in Egypt) are immediate conservation priorities (Mallon and Kingswood 2001, Devillers et al. 2005, Beudels and Devillers 2013). Aerial surveys of the Grand Erg Occidental and Grand Erg Oriental are also urgently needed to establish the current population size.
