The Sunda region refers to a group of islands in Southeast Asia, primarily located in the western part of the Indonesian archipelago. This region includes major islands such as Java, Sumatra, and Bali, as well as smaller islands like Bangka and Belitung. The Sunda region is known for its diverse cultures, languages, and rich natural resources. Geographically, the Sunda region is characterized by its tropical climate, lush rainforests, and volcanic landscapes. The Sunda Shelf, a submerged landmass, connects these islands and plays a significant role in the region's biodiversity. The area is also home to unique wildlife, including the endangered Javan rhinoceros and various species of orangutans.
