Saryarka — Steppe and Lakes of Northern Kazakhstan

Saryarka - Steppe and Lakes of Northern Kazakhstan is a part of the Kazakh Uplands (known in Kazakh as saryarka, or "yellow range") which has been designated a world heritage site by UNESCO. It was inscribed on July 7, 2008, and is the only natural world heritage site in Kazakhstan.

The site comprises the Naurzum State Nature Reserve (located in Kostanay Province) and Korgalzhyn State Nature Reserve (located in Akmola Province). The two reserves contain wetlands which serve as important stop-over points for migrating birds from Africa, Europe, and South Asia. It is estimated that 15–16 million birds, including many endangered species, use the site as a feeding ground. The pink flamingos in particular are a major attraction within Korgalzhyn Reserve.

The site is also home to wildlife commonly found on the Kazakh steppe, including marmots, wolves, and the endangered saiga.
