Boundaries
This wetland is nestled in Shei-Pa National Park. Located upstream in the Dajia river basin is its primary site, the Cijiawan River catchment area, enclosed by mountain ridges and valleys. Also included in the wetland are the central and north valleys of Wuling Farm, adjacent in the south to the west bank of Cijiawan River, with the ridgeline extending westward from Yinian Bridge as its boundary.

Introduction
Cijiawan River is the upstream tributary of the Dajia River basin. The right bank of the valley is broad and plain; on the left bank are several alluvial fan terraces. The river is pristine with an average temperature of 16°C, making it an important habitat for the Formosan landlocked salmon.
The habitat surrounding Cijiawan River is well conserved with sound water quality and quantity management since the boundary of this wetland overlaps with Shei-Pa National Park and Formosan Landlocked Salmon Refuge. It also provides a wealth of resources for eco-tourism undertaken in Shei-Pa National Park. -
Ecological resources of importance
According to the botanical survey of Syue Mountain, which abuts this wetland, 575 species of vascular plants in 95 families are recorded, including 213 endemic to Taiwan. The dominant species along Cijiawan River are Pacific Island silvergrass, Chinese mugwort, Taiwan agrimony and Formosan alder.
There are 122 species of birds from 30 families recorded in the region of Syue Mountain, with the densest avian population in the mixed forests of coniferous and broadleaf trees. The dominant species are Taiwan fulvetta and Taiwan yuhina. There are 9 species of wading birds from 7 families, including a protected species, Tawny fish owl.
Cijiawan River and Gaoshan (Wuling) River are populated with the Formosan landlocked salmon, a species endemic to Taiwan. In the snorkel survey conducted in the summer of 2017, a total of 3,528 were discovered. -

The current situation and potential threats of wetlands
Potential direct or indirect environmental disasters for Formosan Landlocked Salmon in the protected area include typhoons, forest fires, mudslide, and human activities such as logging. Inbreeding is also a crisis for the species due to its small population.
