”Central Range Conservation Corridor“ is connected by protected areas from north to the south. The length of the corridor stretches for 300 kilometers, which accounts for around 17.5% of total island area. In the corridor, Ci-lan, Dan-dan and Guanshan Major Wildlife Habitats were set up for operation due to the organization of the conservation corridor in Central Range proposed by the central government. Therefore, the area was announced as a protected area on February 15, 2000 to patch up the crevice in the north, middle and south of the corridor.

Ci-lan Mountain still maintains a large area of Cedar. Red cedar is one of the most valuable coniferous timbers, and also the largest and oldest tree species. However, after continuous logging during Japanese Occupation and National Government, red cedar has become very rare. Council of Agriculture has passed the announcement to set up “Ci-lan Major Wildlife Habitat” on February 15, 2000.


Cilan Major Wildlife Habitat is located at the administrative intersection of Taipei, Yilan, Hsinchu, and Taoyuan Counties. The range of the habitat covers Compartments 54~71 of Wu-lai Working Circle for National Forest, Compartments 39, 40, 45~66, 83~84, 8700, 109~118, 127~130 and 133 of Da-si Working Circle for National Forest, Compartments 74~77 and 81~84 of Yi-lan Working Circle of for National Forest and Compartments 1~73 of Tai-ping-shan Working Circle for National Forest. The area of this wildlife habitat is 55,991.41 ha. The slice of high mountain region occupies a wide range of land, which starts from Yilan Branch of Central Cross-Island Highway in the east, Jhen-si-bao Tribe of Siou-Luan Village in Jian-shih Township, Hsinchu County in the west, Tang-suei Mountain on the ridge of Central Range in the north and the origin of Dahan River,Takejin River of Dabajian Mountain in the south.

The only access to Ci-lan Major Wildlife Habitat is N. Cross-island Highway located at the north of research area. In the east, Central Cross-island Highway passes through the outer circle. There are lots of forest roads that can access via Sin-sing, Sih-ma-ku-sih, and Jhen-si-bao in Jian-shih Township, Hsinchu County.

Talking about the water system in the mountains, the northern border of the habitat is roughly along Ta-man Mountain (2,130 meters), Mei-kuei-si-mo Mountain (1,871 meters), and Ma-wan-lai Mountain (2,101 meters). The border then turns south to Cilan, while the east border stretches along Lanyang River to further south. Then the border turns west near Liou-mao-an and spans along the ridge of Mei-you-yan Mountain (2,328 meters) and Bian-ji-yan Mountain (2,824 meters). The southern borders neighbor the northeast of Syueba National Park with Bian-ji-yan Mountain and Nan-ma-yan Mountain. The west line lies on the ridge of Nanmayian Mountain (2,933 meters), Ma-wan-lai Mountain (2,551 meters), and Syue-bai Mountain (2,444 meters). The northern border is replaced by the branch of San-guang River near Sinsing. Then it goes along Ta-man River at Dahan Bridge, which later connects Ta-man Mountain.

An Introduction

Ci-lan Mountain is located at the north section of Syue Mountain, which is in the west topographic area of Central Range. The area is mostly composed of thick chunks of mud deposit stones of the Tertiary Period, which have become hardened or transformed. These stones include dark grey black argillite, slate, and phyllite, which have perfect cleavage. The west is mostly argillite, while the stone changes to slate and phyllite in the east.

The area has year-long humidity. it is a typical fog zone of medium and high altitude. According to the six climate zones drawn by Ci C-i-Shu, the protected area is situated at the upper stream of Langyang River and Dahan River, which exactly forms two climate zones: northwest mountain and mid-east mountain. Northwest Mountain usually has cloudy sky and low temperature in summer while in winter the cold air blows down the valley to make more clouds on the plain. Mid-east climate zone is situated at the altitude of 2,000 meters. In summer, the zone is influenced by typhoons; in winter, the area is at the slope that receives northeast wind.

Biological Resources

Wang Jhong-Kuei et al first do the survey on local plants. They, for the first time, discovered Sparganium fallax Graebner and other new companion tree species, which attracted the attention of local conservationists. Soon after, Liou Jing and Syu Guo-Shih conducted ”Yuanyang Lake Nature Reserve Biological Research” in 1973, who recorded 108 species of spermathophyte and 28 species of fern. They also conducted a survey aimed at the aquatic plants in the lake, wetland plant community around the marsh, and forest community in nearby mountains. Another survey was conducted in 1990 topic as “Yuanyang Lake Nature Reserve Vegetation,” which recorded 65 species of fern, five gymnospermae, 182 Magnoliophyta. Chen Yu-Feng et al. had conducted a survey in 1999 aimed at the ecology of cedar forest. They set up 17 sample areas at Chilan Shan trail, Simakusi, and Zhengxi Bao within the habitat. Wang Zheng-Zhe et al. have also conducted a survey on plant species resource and distribution recently in 2001 in Chilan Shan cedar forest. The result recorded 1,009 species of vascular plant.

Ci-lan Mountain still retains a very large area of cedar, which reaches 12,780 ha. The cedar forest can be divided into three major categories, which are pure cedar forest, red cedar and cypress forest, and red cedar forest. Red cedars that are distributed below 1,500 meters are dotted among broadleaf forest. The extent of the forest can be found as far down as 750 meters. The lowest habitat for cypress is around 1,100 meters, while the pure forest is mostly distributed above 1,500 meters. N. Cross-island Highway is at the lowest point of the eastern section. There some natural forest left in some regions, which belong to common tropical ever-green broadleaf forest in the northern low altitude zone. However, there is too much human interference, which enable the growth of other species in the forest. Heading west along N. Cross-island Highway about 700 to 800 meters, the vegetation has changed to ever-green broad-leaf forest of the natural broad-leaf mountain. The dominant plants in the area are mostly Lauraceae and Fagaceae. The area also has some other species of broad-leaf plant in it.

Current Conservation Status

At the western end of the area, it neighbors Fu-sing Township,Taoyuan and Jian-shih Township, Hsinchu County. The eastern border is dong-shan Township, Yilan County, where has settlements of aboriginal tribes. As far as management is concerned, if it could be actively build a cooperative relations with nearby aboriginal tribes and people to conduct mutual communication and governance, and further cultivate tour escort to enhance the understanding of tourists and people. The effort might actively conserve the result of all work.
