Hailed as the sixth largest island in the world, Sumatra is the largest island in Indonesia. Its longest axis runs approximately 1,790 kilometers northwest-southeast which crosses the equator near the center. The island’s interior is dominated by two geographical regions which are the Barisan Mountains in the west and swampy palins found in the east.
The island is covered by tropical rainforest yet economic development coupled with corruption as well as illegal logging has severely threatened its existence. Sumatra is the home to several species like Sumatran Pine, Rafflesia arnoldii, titan arum, Sumatran tiger, Sumatran orangutan, Malayan tapir, Malayan sun bear, Bornean clouded leopard and a lot more.
There are about 10 national parks in the island that include three which are listed as the Tropical Rainforest Heritage of Sumatra World Heritage Site- Gunung Leuser National Park, Kerinci Seblat National Park and the splendid and vibrant Bukit Barisan Selatam National Park.
