From Extinct in the Wild to Endangered: The Remarkable Return of the Scimitar-Horned Oryx
Even as the last scimitar-horned oryx were being killed for meat and leather across the Saharan dunes, a network of zoos, private reserves, and even royal collections quietly ensured the species would survive in captivity.
Now, nine years after these graceful antelope were first reintroduced into the lands they once roamed, they have achieved something nearly unprecedented: they’ve gone from “Extinct in the Wild” to “Endangered.”
Reintroduction Across North Africa
Reintroduced populations in Chad, Tunisia, and Morocco have grown from zero to around 600 wild animals, each carrying a surprisingly high level of genetic diversity for a species once considered lost forever.
This incredible recovery owes itself to a handful of visionary people who acted when the species faced extinction. Among them were West Texas ranchers who, in the 1970s, learned of the oryx’s peril and invested heavily to bring some to Texas. Today, the Texas herd numbers around 12,000 animals, likely more than the species ever had in Africa.
Another key figure was John Knowles, an Englishman who established Britain’s first zoological collection specifically for breeding endangered animals at his 400-acre Marwell Hall estate. There, the Saharan-born oryx thrived in captivity.
The Role of the Studbook
Marwell now manages the scimitar-horned oryx studbook, essentially a detailed breeding record similar to those used for thoroughbred horses. The studbook allowed zoos across Europe to avoid inbreeding and maintain a healthy, genetically diverse population.
Today, the studbook tracks 3,295 animals across 182 institutions, while Marwell also studies the Texas population to determine how to introduce more genetic diversity into the breeding pool. Combined with small herds in Abu Dhabi, these efforts meant the species was genetically ready for a return to the Sahara.
Reintroduction into the Sahara
In March 2016, a cargo plane landed in Chad’s Ouadi Rimé-Ouadi Achim Faunal Reserve, one of the world’s largest conservation landscapes, carrying 25 carefully selected oryx. These animals came from the US, Europe, the UK, and Abu Dhabi and were chosen for their high likelihood of survival and breeding.
“The first phase of the operation has been a success,” said John Newby, who prepared the habitat assessment. “The animals are back in the wild, they’re breeding, and they’re secure.”
Since that initial release, 347 oryx have returned to the wild in Chad, mostly in herds of around 25. Additional populations exist in Tunisia and Morocco, results of earlier reintroduction efforts that had varying degrees of success.
The Triumph of Vision and Persistence
For Phil Robbins, who manages antelopes at Marwell, the most striking moment comes during the releases. “The ‘Wow’ moment is when workers open the doors of the 25 custom-built release crates, and the sword-headed beasts charge into their ancestral home,” he said.
But the real story isn’t the dramatic release—it’s the decades of careful work and the foresight of a few concerned individuals who acted against the tide of extinction. Their vision, dedication, and collaboration across continents made the oryx’s return possible.
Today, the scimitar-horned oryx roam the Sahara once again, a living testament to the power of proactive conservation and global cooperation.
