Features of wetlands
Caodi Wetland is a barrier lake. The Common Cryptomeria and Taiwanese red cypress are dried and dead because of soaking in the water that covers about 2 hectares of the area. It constitutes a special landscape with tall dried trees and water vegetation. Covered with clouds and mists throughout the year, it has become a famous scenic spot – “Lotus Forest”.

Accomplishments of the restoration plan
Caodi Wetland is rich in diverse organisms, most of which are wetland dependent. According to the survey in 2017, it indicates that there are 7 species and 9 types of mammals.

Class II conserved species: Crab-eating Mongoose, Formosan Serow, and Civet Cat
Class III conserved species: Formosan Reeve’s Muntjac and Formosan Macaque

Moltrechti’s Green Treefrog

Amphibians: According to the record, there are 3 species, 8 types of frogs, and 1 specie and 1 type of snake among the amphibians. Among them, Moltrechti’s Green Treefrog, Buergeria Robusta, Swinhoe’s Brown frog, Bufo Bankorensis, and Achalinus Niger are endemic species in Taiwan.

According to preliminary verification, there are 21 species, 26 types of aquatic insects, which are rather diverse. With the family-level biotic index of aquatic insects, water sources represent the index of good water quality with more index insects. However, there is no water supplement in the pond, with plenty of sediment, at the entrance, most of them are dirt tolerant species.

The investigation data shows that this wetland has ample resources, worthy of further monitoring and investigation
