With regard to other conservation projects, we supported the return of the Przewalski's horse to the nature. Przewalski's horse (Equus przewalskii) is the very last surviving wild horse species. The world learned of its existence only in 1881; however, less than a hundred years later, at the turn of the 1970s, it had already been driven to extinction in the wild, surviving only in zoos. The Prague Zoo has significantly contributed to the preservation of the Przewalski's horse. Thanks to the conservation project, there are now over 500 horses living in the wild in Mongolia, of which 194 within a strictly protected area of Gobi B.
