hybrid of Turkmenian Kulan and Persian Onager

Do we know why these hybrid onagers are here? Is it for a reintroduction project of some sort, what exactly is the reason?

@Austin the Sengi yes, two onager subspecies, the Persian onager and the Turkmenian kulan are being reintroduced to their former ranges, including in other regions the Syrian wild ass used to occur in the Middle East. The two subspecies have been reintroduced to the wild of Israel since 1982, and had been breeding hybrids there
