Rhim-; Slender-horned gazelle

Gazella leptoceros (Cuvier, 1842)
French: Gazelle leptocère, Rhim
German: Dünengazelle
Arabic: Rhim

Subspecies
Gazella leptoceros loderi Loder's gazelle

Description
Total length:100 - 110 cm
Tail length: 15 - 20 cm
Shoulder height: 65 - 70 cm
Weight: 14 - 18 cm
Gestation: 165 days

This species is the palest of all gazelles. Both sexes carry long horns, but more slender in the ewes. The hoofs are well adapted to the sandy habitat.

Distribution
G. leptoceros loderi: NW Sudan

Ecology
The Slender-horned gazelle lives in small family groups of females and their youngs, accompanied by an adult ram. Water requirements are drawn solely from moisture in its food.

Conservation Status

IUCN Red List category, ver 3.1:

- http://www.iucnredlist.org/apps/redlist/details/8972/0

Trend:
It is listed on CMS Appendix I and is included in the CMS Action Plan for Sahelo-Saharan Antelopes. The species is present in about 20 collections in North Africa, Europe and North America. The total number in captivity is < 200.

Recommendations

This species' remaining populations are relentlessly pursued by hunters whenever possible and its numbers are probably continuing to decrease. It may persist for some time in small numbers in some of the largest and most inaceesable areas od sand dunes in the Sahara, but if current trends continue it faces eventual extinction in the wild. This trend will only be reversed by active management of viable populations within securely protected areas of its natural range, e.g. through implementation of the CMS Action Plan for the Conservation and Restoration of Sahelo-Saharan Antelopes. This may include reintroduction of the species to areas of suitable habitat.

Loder's gazelle

Gazella leptoceros loderi (Thomas, 1894)

Description
Total length:100 - 110 cm
Tail length: 15 - 20 cm
Shoulder height: 65 - 70 cm
Weight: 14 - 18 cm
Gestation: 165 days

Conservation Status

IUCN Red List Category, ver 3.1:

- http://www.iucnredlist.org/apps/redlist/details/8972/0

Trend: ?
A small number of data, relatively indirect, delimit an area of presence between the zone of the Erdi and the Mourdi depression  in the Borkou of northeastern Chad and the Jebel Uweinat at the borders of Libya, Sudan and Egypt. This is a region in which a numbwe of dunal systems stretch more or less from southwest to northeast. Mention of the species in Sudan come from an optimistic interpretation of data from Chad 1962.

Recommendations
The erg habitat which Loder's gazelle prefers is affected relatively little by the antropic pressures that bear most of the Sahelo-Saharan region, although some authors note the mutilation of ligneous species for firewood. The reoccupation of possible range would thus not seem very difficult, especially since the species has a high rate of reproduction and exhibts migratory or erratic behaviuor, two characteristics that suggest a reasonable colonisation potential. Locally, restoration of the vegetation cover might be necessary, and in all cases protection against human predation and excessive disturbance should be ensured.
