Rhino Extinction Rhino Extinctions Rhinos once roamed many places throughout Europe, Asia, and Africa Rhino Extinctions Rhinos once roamed many places throughout Europe, Asia, and Africa and were known to early Europeans who depicted them in cave paintings. At the beginning of the 20th century, 500,000 rhinos roamed Africa and Asia. By 1970, rhino numbers dropped to 70,000, and today, around 27,000 rhinos remain in the wild. Very few rhinos survive outside national parks and reserves due to persistent poaching and habitat loss over many decades. Three species of rhino—black, Javan, and Sumatran—are critically endangered. Today, a small population of Javan rhinos is found in only one national park on the northern tip of the Indonesian island of Java. A mainland subspecies of the Javan rhino was declared extinct in Vietnam in 2011.
