Wilhelma also participates in several projects for repatriating animals or setting them out into the wild again. And so alpine ibexes from Wilhelma are now living in the wild in the Rauris Valley in Austria, Wilhelma capercaillies inhabit the Black Forest anew and Wilhelma Przewalski's wild horses are living wild in Mongolia. This, too, is a contribution to the preservation of the species. It is, however, only possible to set animals from zoo stocks out in the wild in their old home countries if the new habitat offers them enough to eat and protection from poaching. For this reason nature reserves or protected areas are established.
