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. After a further decline during the Second World War, the number of European mouflon worldwide in 1954 was only about 4,500. After that, numbers recovered due to careful management and grew
Wild horse cranial and metacarpal differences, indicates the presence of only two subspecies in postglacial times, the tarpan and Przewalski's horse. At present, the domesticated and wild horses are considered a single species, with the valid scientific name for the horse species being "Equus ferus." The wild tarpan subspecies is "E. f. ferus", Przewalski's horse is "E. f. przewalskii", and the domesticated horse is "E. f. caballus". The rules for the scientific naming of animal species are determined in the International Code of Zoological Nomenclature, which stipulates that the oldest available valid scientific name is used to name the species.
