Persian onager found in desert steppes. Their largest population is found in Khar Turan National Park. The Persian onager is listed as endangered by IUCN Red List, as it is close to extinction. Currently, poaching for meat and hides, competition with livestock, and drought are the greatest threats to this species. Asiatic wild asses are highly and legally protected; hunting them is forbidden. The European Endangered Species Programme reserved for European Association of Zoos and Aquaria is helping save the Persian onager from extinction, by breeding them in captivity and reintroducing them to their former ranges, including in new locations once inhabited
