Kenting National Park Headquarters

The wetland is located within Nanren Mountain Reservation Area of Kenting National Park. The wetland consists of three lakes that never dry up, including the main water body, the detached Nanren Lake, and Yilan Lake (Ancient Nanren Lake).

Nanren Lake Important Wetland is located in the Nanren Mountain Reservation that is in the northeast corner of Kenting National Park. Located south of the tropic of cancer, the area is populated with tropical forests. The influence of monsoon and down-slope wind creates an environment where temperate, subtropical and tropical forests coexist while each is being compressed. This area is important for long term research on the habitat. Nanren Lake Important Wetland is the largest confined water habitat within Nanren Mountain Range. Located in the lowland, Nanren Lake and the main water body gradually became fresh water marshes because of drainage issues. In the past, the water from the wetland could flow north through Hongtu River into Zhongang River. In 1982, the levee was built. Hongtu Estuary was waterlogged due to human factors and gradually formed the central water body. Yilan Lake is a small lake that took shape naturally.

The wetland is home to 37 families and 92 species of plants, including 22 families and 51 species of aquatic plants, including submergent plants such as bamboo plant and ricefield water-nymph; floating plants such as floating bladderwort; floating-leaved plants such as Nymphoides coreana and water lilies; 46 emergent plants. In terms of rare plants, 7 Taiwanese vascular plants are found in this wetland, including 1 vulnerable species, Nymphoides coreana; 3 near threatened species and 3 least concern species.
There are 5 families and 10 species of fish. Among them, 3 families and 5 species are endemic, including 1 Anguillidae, 1 Channidae and 3 Cyprinidae. Channa maculata is considered Near Concern by IUCN. Giant mottled eel was once listed as protected species. The flowerhorn cichlid is the dominant species and an important source of food for the birds.
There are 38 families and 77 species of birds, including 17 protected species. In the lake area, the Indian spot-billed duck accounts for the largest group of birds and can be seen year round.
