Chiayi County Government

The wetland is located in Dongshi Township of Chiayi County and partially in Budai Village. It extends northeast to Harbor Bridge in Chiayi County with the river bank of both sides as boundaries; west to the southern tip of Waisanding Sandbank and south to Budai Harbor, including the old salt pans, fish ponds, and detention basins in the land subsidence area west of Provincial Highway 61.

Puzih river basin was developed quite early thanks to Puzih River supplying water for agricultural, fishery, and public uses. This area enjoys well developed industrial, commercial, agricultural, and fishery sectors and high population density. In the period of industrial and commercial boom in the 1960s, there were many industrial parks on both sides of Puzih River, including major companies in automotive, electromechanical, pulp and paper, textile and plastic industries, driving the rapid growth of small and medium-sized factories and accelerating further industrial development in this area.

The tidal section at the downstream near Puzih Estuary is a wider and larger area with sandbank, wetland and larger river bed. It is also home to halophytes, sand plants and mangroves as well as invertebrates on the coastal mudflat and intertidal zone, such as fiddler crabs, mud skippers, snails, and gastropods. The organic debris from mangrove trees becomes food and baits for fish and shrimps, contributing to the vibrant growth of the local fishery industry and bird species.

Land subsidence and excessive pumping of underground water near the Chiayi coast has led to prolonged seawater submersion of Avicennia marina roots, causing withering of mangrove areas along the upper reaches of the estuary.
