Tengzhi Research Center
Background
    Endemic Species Research Institute was founded and assigned to conduct research and conservation for endemic and rare species in Taiwan. In order to provide proper research facilities for this purpose, the Medium Altitude Experimental Station was thus proposed on 5 August 1991. After transferring a land of state-owned forest, ca. 219 hectares, entrusted by the Forestry Bureau to Endemic Species Research Institute’s administration on 30 December 1993, Medium Altitude Experimental Station was formally established on 26 April 1995. Endemic Species Research Institute have been reorganized into Biodiversity Research Institute since Council of Agriculture was reorganized into Ministry of Agriculture on 1 August 2023. Also, Medium Altitude Experimental Station was reorganized into Tengzhi Research Center at the same time.
Missions
(1) Investigation and research on unique ecosystems in the medium altitude area of Taiwan.
(2) Conservation and research of endemic and rare fauna in the medium altitude area.
(3) Conservation and research of endemic and rare flora in the medium altitude area.
(4) Long-term (permanent) monitoring of biodiversity in the medium altitude area, including subjects of organisms, ecosystems, environments, climates, and global changes.
Area
    The research center is located at the Tengzhi area in Baoshan Village, Taoyuan District, Kaohsiung City (N 23°05', E 120°47'). It borders to the east by the Shishan Mountain of the Central Mountain Range and to the south by the Chuyunshan Nature Reserve, covering an area of 219 hectares approximately. The elevation ranges from 1,100 to 2,635 meters, with an average annual temperature of about 15℃ and an average annual precipitation of about 2,200 millimeters. The majority of vegetation is natural forest which harbors intact natural environments and abundant fauna and flora resources. The vegetation comprises forest zones of Hemlock and Spruce, Fagaceae, and Machilus-Castanopsis zone. It has excellent conditions for long-term investigation and research in the indigenous evergreen conifer-broadleaf forest ecosystems mentioned above.

4. Amphibian: 3 families, 6 species, including 2 endemic species. Endemic species include Central Formosan Toad and Moltrechtis’ Green Treefrog, whereas others are Eiffinger’s Treefrog, Swinhoe’s Frog, and Heymonsis Narrow-mouthed Toad.
5. Insect:

1. Butterfly: 10 families, 109 species, with 9 endemic species. Endemic species include Aurora Swallowtail, Pink-spotted Windmill, Formosan swallowtail, brush-footed butterflies, and five-rings, etc.
2. Moth: 24 families, 722 species, with 140 endemic species and 51 endemic subspecies, comprising Golden Moon Moth, Giant Silkworm Moth, Grey Double-bristled Hawkmoth, Holy Butterfly, prominent moths, and geometrid moths, etc.
3. Coleopteran: 29 families, 477 species, including Rainbow Sheath Click Beetle, Long-fanged Stag Beetle, and Formosan Long-armed Scarab.

2. Flora

A total of 103 families and 256 genera of vascular plants species were recorded in this area, comprising 129 endemic species and 30 rare ones. The predominant vegetation type is primary broad-leaved forest, followed by understory conifer-broadleaf mixed plantations of and pure coniferous stands. Primary broad-leaved forests are composed of the species of Machilus, Castanopsis and Formosan Michelia, whereas the same three species together with Taiwan Red Cypress, Taiwan Incense Cedar, and Jelly Fig dominate understory conifer-broadleaf mixed plantations. Tree species in pure coniferous stands are primarily Taiwan Red Cypress and Taiwania.
