Hapen and Fushan

Year of compilation: 2001

Site description
Extent of this site: the north portion of the Fushan Botanical Garden, and the south portion of the Hapen Nature Reserve. It is bounded on the north by Ayu Mt. with the height of 1419 m, on the south by Hongtsi Mt., and on the west by Chihliangchiu Mt. On the east side is the watershed of the Zukeng Creek, a branch of the Lanyang River, and on the west is the Hapen Creek watershed, an upstream portion of the Nanshih River; from east to west, the area stretches 4.3 km. The Hapen Nature Reserve encompasses an area of 332.7 ha, including national forests which straddle the boundary between Taipei and Ilan Counties, separated into the Wenshan forest administrative district compartment No. 72 and No. 15’s second small compartment, and the Lanyang Forest District’s administrative compartment No. 54, 56, and 57. The Fushan Botanical Garden encompasses 409.5 ha and has milder slopes; within the garden there are about 16 km of tourist trails, promoting outdoor education. This site has a temperate, humid climate; the terrain is undulating. Because this area is secluded, and transportation is not convenient, most of the area maintains the most complete mid- to-lower elevation broadleaf forest in Taiwan, with the dominant plants of the Lauraceae and the Fagaceae families.

Key biodiversity
IBA A2 criterion species: 8 endemic species are commonly seen here: including Formosan Whistling Thrush, White-throated Hill Partridge, Formosan Blue Magpie, White-eared Sibia, Formosan Yuhina, Formosan Yellow Tit, Swinhoe’s Pheasant and Steere’s Liocichla. • At this site 141 species of birds have been recorded, among which are the rare Tawny Fish Owl, Indian Black Eagle, Asian Crested Goshawk, Black-faced Cuckoo Shrike, Formosan Blue Magpie, Mandarin Duck, and Spotted Scops Owl. • In fall, flocks of passing wild Mandarin Ducks will stop and rest at the Fushan Botanical Garden.

Non-bird biodiversity: • 515 species of vascular plants in 329 genera and 124 families are recorded at the Fushan Experimental Forest. • Commonly seen wildlife include the Formosan Reeve’s Muntjac Muntiacus reevesi micrurus, Formosan Wild Boar Sus scrofa taivanus, and the Emerald Green Tree Frog Rhacophorus smaragdinus.

Pressure/threats to key biodiversity
• There is pressure from recreational activities; although there are frequent mountain patrols of the Experimental Forest, tourists still illegally enter the protected areas. • There are still illegal hunting and felling of trees.

Conservation responses/actions for key biodiversity
Legislation • In June 1986, the Council of Agriculture designated the southern part of this area the Hapen Nature Preserve according to the Cultural Heritage Conservation Law. Important preservation targets are the natural broadleaf forests and the wild animals and plants within these habitats, for supporting a genetic reserve and long-term investigation, education, and research. Facilities such as interpretative boards and a management station are also well set. • In 1987, the Taiwan Forestry Research Institute planned the Fushan Botanical Garden, and on 1 November 1990, they set up the Fushan Division. Here a demonstration botanical garden was established for scientific research. In 1993, the botanical garden was chosen as one of the nature education centers by the Education Ministry to implement outdoor education for junior high school teachers. • In 1992 with donation of funds from the National Science Council, the first Long-Term Ecological Research (LTER) Station was established in Taiwan, called the Fushan Forest Ecosystem where the Hapen Nature Reserve was included. It was planned that three 9-year periods would be needed for researchers from various disciplines to conduct related research. The objective of this plan is to enhance the understanding of the structure and impacts of the forest ecosystem.
