Le Villaret, located in the Cevennes National Park in southern France and run by the Association Takh, is a breeding site for Przewalski's horses that was created to allow the free expression of natural Przewalski's horse behaviors. In 1993, eleven zoo-born horses were brought to Le Villaret. Horses born there are adapted to life in the wild, being free to choose their own mates and required to forage on their own. This was intended to produce individuals capable of being reintroduced into Mongolia. In 2012, 39 individuals were at Le Villaret. An intensely researched population of free-ranging animals was also introduced to the Hortobágy National Park "puszta" in Hungary; data on social structure, behavior, and diseases gathered from these animals are used to improve the Mongolian conservation effort. An additional breeding population of Przewalski's horses roams the former Döberitzer Heide military proving ground, now a nature reserve in Dallgow-Döberitz, Germany. Established in 2008, this population comprised 24 horses in 2019.
