Involved in Shuangguei Lake Major Wildlife Habitat.

The wetland is situated at the borders between Maolin District of Kaohsiung City and Yanping Township of Taitung County, extending to the northern side of Yaobai Mountain in the south section of the Central Mountain Range. The total area includes three lakes of different sizes: Daguei Lake, Daguei East Lake and Daguei West Lake.

The main part of the Daguei Lake is the deepest natural mountain lake in Taiwan. The location of the wetland is at the western foothill of the Central Mountain Range Ridgeline. Being the holy land for Rukai Tribe, Shanhuanu River, originating from the rivers and forests in this area, flows into Zuokuo River, which is the source of Launong River, the most important tributary of Kaoping River System.
The forests are full of diverse ecologies and flora and fauna. In 2000, Council of Agriculture of the Executive Yuan designated the area between Daguei Lake and Xiaoguei Lake as Twin Guei Wildlife Habitat of Importance in the effort to protect the most pristine mountain lakes and the surrounding virgin forests.

With its complex terrains, elevations and climate, Twin Guei Wildlife Habitat of Importance is also the natural environment with diverse forests, including broadleaf forests, mixed forests, and coniferous forests. According to the survey on terrestrial animals, there are 16 families and 31 species of mammals, including the protected Formosan black bear, Formosan yellow-throated marten and Herpestes urva. There are also 57 species of birds, 14 endemics species and 25 subspecies and 19 protected species, such as Hodgson’s hawk eagle and Ictinaetus malaienisis.

Formosan Clouded Leopard (of which there has been no recorded observation in many years), Hodgson's Hawk Eagle.

Formosan Serow (Naemorhedus swinhoei), Formosan Sambar, Mandarin Duck, Mikado Pheasant, Swinhoe's Pheasant.

Formosan Rocky Monkey (Macaca cyclopis), Formosan Barking Deer

Based on both aborigines' oral descriptions and field researchers' observations regarding hunting and trapping, we can assume that excessive hunting is still a very serious problem in the wetland.
