The Pontic–Caspian Steppe, extending across Eastern Europe to Central Asia, is formed by the Caspian and Pontic steppes, which stretches from the northern shores of the Black Sea to the northern area around the Caspian Sea, where it ends at the Ural-Caspian narrowing, which joins it with the Kazakh Steppe in Central Asia, making it a part of the larger Eurasian Steppe.
