The Arabian Oryx Was Declared Extinct in the Wild in 1972. In 1982, Captive-Bred Animals Were Reintroduced in Oman. Today Over 1,200 Live Wild Across the Arabian Peninsula. It Was the First Species Ever Saved From Wild Extinction by Captive Breeding.
The template was written in the Arabian desert. Every subsequent de-extinction attempt references it.
Oryx leucoryx — the Arabian Oryx — was the first mammal to be declared extinct in the wild and subsequently reintroduced from captive populations. Its extinction: the last wild individual was killed in Oman in 1972, by hunters using automatic weapons from trucks. The species had declined from tens of thousands to zero in less than a decade.
What survived: nine individuals that had been captured for a captive breeding programme — the "World Herd" — established at Phoenix Zoo, Arizona, in 1962. Over the following decade, the captive population grew to around 90 animals.
In 1982, 10 captive-bred Arabian Oryxes were reintroduced to the Jiddat-al-Harasis plateau in Oman — in collaboration with the Harasis tribe, whose members became the first wildlife rangers. The reintroduction was precarious: the Oryxes had to relearn desert survival skills not needed in captivity.
By 1994: 400 wild individuals in Oman. The IUCN downlisted from Extinct in the Wild to Endangered.
Today: over 1,200 wild individuals across Oman, Saudi Arabia, UAE, Israel, and Jordan. The IUCN current listing: Vulnerable. A species that was at zero wild individuals in 1972 is now at Vulnerable — three full IUCN categories of improvement.
The Arabian Oryx recovery established the proof of concept for every captive breeding and reintroduction programme that followed.
If the Arabian Oryx — declared extinct in the wild in 1972 — is now Vulnerable with over 1,200 wild animals, what does that say about what is possible for species that are currently at their lowest points?
