Orchid Island, known as Pongso no Tao by the indigenous inhabitants, is a 45 km (17 sq mi) volcanic island located off the southeastern coast of Taiwan. The island and the nearby Lesser Orchid Island are governed by Taiwan as Lanyu Township in Taitung County, which is one of the county's two insular townships (the other being Lyudao Township). It is separated from the Batanes of the Philippines by the Bashi Channel of the Luzon Strait.
It is considered a potential World Heritage Site.
Green Island, also known by other names, is a small volcanic island in the Pacific Ocean about 33 km (21 mi) off the eastern coast of the main island of Taiwan. It is 15.092 km (5.83 sq mi) at high tide and 17.329 km (6.69 sq mi) at low tide, making it the seventh-largest island in Taiwan. The island is administered as Lyudao Township, a rural township of Taitung County and one of the county's two insular townships (the other being Lanyu Township). The island once served as a penal colony for political prisoners during Taiwan's period of martial law, although today it is primarily known as a tourist hotspot.
The Kavalan (endonym kbalan [kɨβaɾán]; "people living in the plain"; Chinese: 噶瑪蘭族) or Kuvalan are an indigenous people of Taiwan. Most of them moved to the coastal area of Hualien County and Taitung County in the 19th century due to encroachment by Han settlers. Their language is also known as Kavalan. Currently, the largest settlement of Kavalan is Xinshe (Kavalan: pateRongan) Village in Fengbin Township, Hualien County.
