Takhi, the only wild horse is one of the seven equid species in the world. The last Przewalski's horse was observed in 1969 in the wild. After this, takhi was listed in IUCN Red List Category as "extinct in the wild". In the beginning of 1980, National Commission on Reintroduction of Takhi of Mongolia was established with aim to support reintroduction efforts and was responsible for assigning adequate land and overseeing preparation work. Based on a feasibility study conducted in 1999-2000 by a joint research team of the French Association TAKH, WWF Mongolia, Institute of Biology of the Mongolian Academy of Sciences and other organizations, Khomyn Tal was selected as the third reintroduction site for Przewalski’s horses in Mongolia. In spring 2001, Agreement of Cooperation was signed between Association TAKH and Durvuljin soum Governor. According to the Agreement, Durvuljin soum granted 30 years of special grazing rights to the Association TAKH for the purpose of reintroducing Przewalski's horses in 25,000 hectares of a Local Protected Area around Seeriin Nuruu.
In 2011, another four takhi arrived in Khomyn Tal from Czech Republic with direct support of Prague Zoo. This time, the horses underwent a strenuous journey by trucks from Khovd airport to Khomyn Tal, in total of 280 km on dirt road. These individuals significantly contributed to increase of genetic diversity and decrease of inbreeding coefficient of bottle necked Przewalski's horse population of Khomyn Tal.
Thanks to successful work of the Mongolian and French team for reintroduction and continuous support of the donors and the Government of Mongolia, the Przewalski's horses population in Khomyn Tal has reached 89 individuals composed of 7-8 herds. This spring, 20+ new foals are expected to born in Seeriin Nuruu. Within the framework of cooperation with other two reintroduction sites - Great Gobi B Strictly Protected Area and Hustai National Park, translocation of a small group is planned in the near future, with the purpose of genetic diversification. Khomyn Tal is expected to upgrade it's status to a National Park with 411,403.78 ha covering entire Khomyn Tal with extended area to the north, along the Zavkhan River.
