Extent of this site: to the south is Ilan County Road 30; to the west is Han County Road 25; to the north is the Provincial Highway 7; and to the east is the Provincial Highway 2. This area contains the Dongshan River. The area is also called Wushierjia (means 52 ha), because historically, the Ilan People once reclaimed and cultivated an area of about 52 ha here. Before the 1980s, the water channel of the Dongshan River twisted and turned, which made the drainage of the water from torrential rains of typhoons very difficult, and thus caused flooding disasters which created the freshwater wetlands nearby. Later, the dredging of the Dongshan River continued according to the Dredging Plan of Provincial Rivers. The Wushierjia Wetlands consists of the nearby paddy fields and the marshes formed from abandoned cultivated fields. Because of the abundant food resources and the location of the wetlands, each year, large numbers of the Scolopacidae, Charadriidae and waterfowl spend the winter here. All lands in this area are privately owned. Due to high costs of land acquisition and opposition from landowners, the government has found it difficult to establish a bird reserve in this area. Wushierjia Wetlands is located close to the Dongshan River Scenic Area. Integrating the two areas together would provide greater diversity in scenic spots for tourist activities and ecological education.
