Taiwan
Taiwan , also known, especially in the past, as Formosa , is the largest island of the same-named island group of East Asia in the western Pacific Ocean and located off the southeastern coast of mainland China. The island forms over 99% of the current territory of the Republic of China following...

. Formosan sika, like most of the terrestrial fauna and flora of Taiwan, arrived on the island during Pleistocene glacial periods when lower sea levels connected Taiwan to the Asian mainland.

Appearance and Behavior

Sika stand 90-120 cm at the shoulder. Males are larger and bear deciduous antlers. The summer coat is light brownish, with obvious white spots, while in winter their coat is darker and the spots fade.

Range and Habitat

The natural distribution of sika on Taiwan was in the woodlands from sea level up to about 300 m elevation. Sika, like many deer, prefer areas of mixed forest, scrub, and open land. Under natural conditions the low-lying alluvial plain that stretches from present-day Taipei along the west coast almost to the southern tip of the island were prime deer habitat and natural populations would have been quite dense.

Status

Sika populations in Taiwan have been heavily influenced by human activity for the past four hundred years. Until the early 17th century the human population of Taiwan was low and comprised mostly Austronesian peoples
Taiwanese aborigines
Taiwanese aborigines is the term commonly applied in reference to the indigenous peoples of Taiwan. Although Taiwanese indigenous groups hold a variety of creation myths, recent research suggests their ancestors may have been living on the islands for approximately 8,000 years before major Han...

who had been living on the island for 1000’s or years. During the 17th century immigration from the Chinese mainland increased dramatically in response to political instability in China and economic opportunities on Taiwan, which from 1624 until 1684 was controlled by the Dutch East India Company. The company, operating from the port of Taiwanfu (now Tainan) in southwestern Taiwan, established a trading post whose main business was the export of sika skins to Europe. During the six decades of Dutch activity two to four million sika skins were exported to Europe. Exporting was reduced when the Dutch were forced out of Taiwan in 1684, but continued throughout the Qing period with a switch to Japan as the major export market.

The intensive hunting of sika during the Dutch era must have severely decreased the population of sika. Sika populations continued to decline over the next few centuries as the human population expanded—the natural habitat of sika in the lowland plains was steadily converted to farmland, and later urbanized, as the human population increased. Hunting also continued. As a result, wild sika populations decreased steadily, and in 1969 the last known wild sika was killed.

However, deer are easily kept in captivity and there were a number of captive populations of C. n. taiaoanus. In 1984 Taiwan’s Council of Agriculture funded the Sika Deer Reintroduction Project, based at Kenting National Park on the southern tip of the island. Twenty two deer were transferred from the Taipei zoo to serve as a founder population. Over the next 10 years the deer were maintained in enclosures until their eventual release into the National Park in 1994. Altogether over 200 deer have been released and the current population, now spread beyond the park borders, is estimated to exceed 1000 individuals. Discussions regarding other possible reintroduction sites, including Yangmingshan National Park near Taipei, are ongoing.
