The island was originally inhabited by the aboriginalAmis people. In March 1864 the BritishbrigSusan Douglas was swept off course and wrecked on the island. Her captain then sailed by junk from the island to Kaohsiung, and the Royal Navy gunboat HMS Bustard found and rescued the remainder of the survivors. In the early 1870s, William Campbell saw the island from aboard the Daphne, and wrote: On 11 December 1937 the Dollar Steamship Company luxury ocean liner ran aground in a typhoon on a reef at Zhongliao Bay. All 503 passengers and 330 crew survived and were safely brought ashore. Over the next few days the cargo liners SS President McKinley and SS President Pierce took the survivors off the island, helped by boats provided by the and an Imperial Japanese Navy destroyer. Dollar Lines sold President Hoovers wreck to a Japanese salvage company, which spent the next three years breaking her up in situ. In response to the wreck, members of the US public gave money through the American Red Cross for a lighthouse to be built near Zhongliao village. Lüdao or Lu Tao Lighthouse was designed by Japanese engineers, built by local islanders in 1938 and is high. A shipwreck of Dutch origin dating to the 19th century was found in June 2013.
Prisons
Green Island first served as an isolated spot and place of exile for political prisoners during the martial law period of Taiwanese history under the Kuomintang, and especially in the White Terror. After their release, many of the prisoners jailed between the late 1940s and the late 1980s went on to establish the Democratic Progressive Party, most notably Shih Ming-teh. Cartoonist Bo Yang served his prison terms there. The place where most of the political prisoners were held was "Green Island Lodge". "Oasis Village" was the main penal colony. The prison was later closed, and its interior is now open to the public. "Green Island Prison" is also on the island and has housed prisoners considered to be among Taiwan's most dangerous criminals and gangsters. However, this has changed in recent years.
The island is a habitat for Formosan sika deer, Reeves's muntjacs, Ryukyu flying foxes, and resident and migratory birds.
Local population
In 1995 fewer than half of the registered 2,634 residents of the island actually lived on the island. The population is dwindling due to the difficulty of finding jobs on the island. The island has two pre-schools, one kindergarten, two elementary schools and one middle school. To pursue any education at the senior high school level or above, islanders must move to the main island of Taiwan. Public service centres include one seniors' home, one library, and one community centre. The villages and the settlements they administer are:
