Larger than California and Oregon combined, Madagascar is the world's fourth largest island, after Greenland, New Guinea and Borneo. Located 250 miles off the south-east coast of Africa, the island extends 1,000 miles in length and 360 miles at its largest width. The island can be divided into three main parts: the East Coast, a narrow coastal strip abutting the steep slopes of the North-South mountain range, home of the rain forest; the Central Highlands, averaging 2500 to 4500 feet in altitude and culminating at 9430 feet, decorated with immense rice fields; and the West Coast, home of the baobabs and thorny forest. Coral reefs fringe a portion of the coast. Most plants and animals found in Madagascar exist only there.
