The Turkmenian kulan or Transcaspian wild ass (Equus hemionus kulan), also called simply the kulan, is a subspecies of onager (Asiatic wild ass) native to Central Asia. It was declared Endangered in 2016. The species's population had recently been in decline in the country while it slowly increases in reintroduction sites. The Turkmenian kulan has been reintroduced to Kazakhstan, Uzbekistan and Ukraine, where the onagers formerly existed, also in Israel, where the subspecies are making hybrids with Persian onagers in the wild.
