French: Addax, Antilope Blanche
German: Mendesantilope; Addaxantilope
Spanish: Adax
Arabic: Begar el Ouach, Akash, Tamita


Regional endemic subspecies

No valid subspecies have been described.


Description

Total length: 1.20 - 1.75 m
Tail length: 27 - 35 cm
Shoulder height: 95 - 115 cm
Weight: (m) 100-135 kg, (f) 60-90 kg
Gestation: 252 - 267 days

This pale antelope has a chocolate-brown tuft on the forehead and a white mas around the eyes. Both sexes carry spiralled horns.


Distribution
Regionally extinct. The Addax antelope was formerly distributed in NW Sudan. Today, if at all possible, only vagrants from Chad might enter Sudan.


Ecology

The addax is well adapted to harsh conditions like sand-dune deserts and stony plateaus. It is mainly active at night and at dawn and dusk. Formerly it tend to live in groups of up to 20 animals, but today much smaller. Migratory herds of hundreds are now past.

Recommendations

Generally only a large-scale regional approach will guarantee the survival of a viable and genetically robust population. Recognizing the special challenges posed by highlymobile, wide-ranging desert species, new approaches are needed to complement more traditional ones based on the control of poaching and the establishment of parks and reserves. Approaches are needed that are as flexible and as mobile as the addax itself, and in the vastness of the Sahara it is with the nomadic human population that the best chance of finding solutions exists. A proposal to establish a protected area in Wadi Howar in N Darfour would provide an opportunity to restore populations of Addax if it became necessary and feasible. Considering the degraded conditions of the steppe areas in Sudan, substantial habitat restoration measures may be a necessary prerequisite. To control poaching within large protected areas may be extremely difficult.
