               Steppes in the world
               Steppes are a type of habitat consisting of
               grassland plains without many trees. They
               are found in a huge belt across central
               Eurasia, stretching all the way from Ukraine
               to China and Russia. There are also steppes
               (prairies) in North America, and a similar
               habitat type in some tropical regions.

            Przewalski’s horse
            The Przewalski’s horse is an endangered
            subspecies of wild horse, which lives in small
            herds. It became extinct in the wild in 1966, but
            was reintroduced to Mongolia in 1992. There
            are now thought to be over 300 horses, which
            feed on grassy vegetation and migrate between
            water sources to survive periods of drought.
