European mouflon Harzgerode in 1906, followed by further releases in the Taunus and the Solling. In all cases, the mouflon favoured level or low-lying plains with forest cover and not, as expected, rocky, mountainous areas. Gradually they were mixed with varieties of domestic sheep, especially crossbreeding with the racka. After the European mouflon population declined during the First World War, in the German Reich alone about 2,500 were counted in 1938.

Somali wild ass home to eleven Somali Wild Asses, the largest population of Somali Wild Asses in North America. The park received its first herd from the Basel Zoo in 1981. Their first foal was born in 1986. Since then, 49 foals have been born, the most recent being a female born on March 17, 2018. San Diego Zoo Global also works to help save this endangered species in the wild. Domestic donkeys found in Italy are typically descended from the Somali wild ass, as opposed to those from other European countries where domesticated stock are usually descended from the Nubian wild ass.
