However, often it is particularly this part which is hard and longwinded to achieve, for either financial or social reasons. One successful example for saving an animal species by breeding it in captivity is Przewalki's horse (tahki) which is ancestor to all our present horse species. In it's former home, Mongolia and China, it was eradicated in the 1960s. In 1992, the Christian Oswald Foundation started a project with the aim to resettle those horses in Mongolia. This project is being followed-up by the International Tahki Group. Tiergarten Nürnberg supports this project with horses from its own breeding group. The animals come from different zoos in order to maintain and secure the genetic diversity and to avoid inbreeding.
In 1997, the first group of horses was released into the steppe of the nature reserve Gobi B. Two further groups, some of the animals marked with collar-transmitters, followed suit in 1998. The following year they had their first offspring: two foals. In 2002 already 10 foals were born. Meanwhile the population has increased to 36 animals in the wild and 22 horses still kept in enclosures. Luckily, the horses cope well with their native habitat conditions - extreme weather conditions and the permanent threat of nearby wolf packs.
