8 Abstract This study reviewed the history of Yang Min Shan National Park in terms of its establishment, vegetation studies, production activities and vegetation changes since Ching Dynasty. A total of 39 square-shaped sampling plots, each 100m 2 in size, were set up for vegetation analysis, so as to identify the vegetation types of the area. The Yang Min Shan National Park was formerly named Tatun Nature Park in 1937 during the Japanese occupation. After Taiwan regained, it was handed to the Yang Min Shan Administrative Bureau in In 1963, the Yang Min Shan National Park Project was launched, and the national park was formally established in Vegetation studies of this area was started by British scientists during the Japanese occupation and Japanese scientists then followed. Vegetation specimens were collected and several floras were published. The earliest literature mentioned about the vegetation of this area was The Article of Taiwan Journey authored by Yun-Ho Yu in 1879 (5 th year of the Kuan-She emperor, Ching Dynasty). During the Japanese occupation, there were several reports about the forestation and vegetation of the area, authored by Oobash Juanichilo, Shitagawa Hagilo, Sasaki Juanichi, Shibahara Kamio, Fujihara linichi, and Partners for Taiwan Plants. After the war, more thorough vegetation surveys were conducted by the Yang Min Shan Administrative Bureau. Vegetation changes in the area were highly correlated to production activities. Grazing and productions of Baphicacanthus cusia, teas, Ditto rice, oranges, vegetables and flowers had contributed to the vegetation changes in various degrees. Among them, the prosperous tea production during the Kuan-She emperor, Ching Dynasty, and during the Japanese occupation ( ) had seriously destroyed the vegetation. Original vegetations were removed for tea farming, and VI

9 Acacia trees (Acacia confusa) were planted to provide fuel woods for baking teas. As a result, Acacia trees can be found all over the area now. Forestation was also a contributing factor to vegetation composition. During the Japanese occupation, reforestations were conducted at the Tatunshan, Chisingshan, Tsaikungkengshan, Mietienshan and Shamaoshan under the Tatunshan Reforestation Campaign, and at the Hsiaokungyinshan and Chutzushan under the Inner-Tatunshan Reforestation Campaign. As a result, totally 2,763 Chinese hectares ( ) (2680 ha) of plantations were reforestated, mainly Pinus massoniana, Pinus luchuensis, and Pinus thunbergi. However, after illegal cutting and natural succession following the end of war, forestations on the mountain were gone, and the trace of forestation can only be identified by some remaining trees within the secondary forests. Results of vegetation analysis showed that the man-made forests in the area can be classified into four vegetation types, namely (I) Cinnamomum camphoraficus microcarpa AssociationIIAcacia confusaliquidambar formosana AssociationIIICryptomeria japonica AssociationIVPinus luchuensis Association After the establishment of national park, the production activities had reduced significantly. Although the original vegetation had undergone massive destruction, fortunately the destruction did not last a very long time from the point of view of vegetation succession. Current vegetation conditions suggest that succession is starting over again. The damaged lands are recovering, and the forests will reach the climax in the future.
