Scimitar-horned oryx (Oryx dammah) is a Sahel–Sahara antelope once widespread across North Africa. Heavy hunting and habitat loss caused its disappearance from the wild; it is now listed as Extinct in the Wild (EW). Since 2016, reintroduction projects in Chad have built free‑ranging, breeding herds supported by GPS tracking and aerial monitoring.
Range & Habitat
Semi‑arid grasslands and thorn scrub on sandy/stony plains along the Sahara fringe; today mainly within reintroduction areas and fenced reserves.
Ecology
Herds track fresh growth after rain; diet includes grasses, herbs and Acacia pods. A pale coat reflects heat; activity peaks in cool hours. Long, scimitar‑shaped horns are used for defence and social display.
Reproduction
Breeding age 2–3 years; gestation ~8–9 months; single calf. Wild lifespan 15–18 years, longer under management.
Threats & Conservation
Historic overhunting and proliferation of firearms.
Habitat degradation/fragmentation from overgrazing and infrastructure.
Climate variability and prolonged droughts.
Recovery depends on ex‑situ breeding, staged releases, anti‑poaching patrols, community partnerships and genetic management.
