After the extinction of the Syrian wild ass, the Persian onager from Iran was chosen as the appropriate subspecies to replace the extinct onagers in the Middle East. The Persian onager was then introduced to the protected areas of Saudi Arabia and Jordan. It was also reintroduced, along with the Turkmenian kulan, to Israel, where they both reproduce wild ass hybrids in the Negev Mountains and the Yotvata Hai-Bar Nature Reserve.
