Site description (baseline)
Extent of this site: to the south is the levee on the south bank of the Lanyang River to the Coastal Highway (Provincial Highway 2), from the Jiafuyuan Bridge to the seaside at Chingshui; on the east the site extends 500 m off the shoreline; to the north is Gongguan, the Chuangwei Bridge, and the Hsingang Bridge; and to the west is Provincial Highway 9. Located between Ilan City and Luodong Township, the area around the Lanyang River Estuary consists mostly of riparian wetlands and includes the rivermouth and agricultural fields on the north riverbank between Hsinnan to Meifu forming an important habitat for migratory and wintering birds. The Lanyang River Estuary is formed by the convergence of the Lanyang, the Ilan and the Dongshan Rivers. It is the most important estuarine wetland in Ilan County, providing an excellent environment for migratory birds on their way north and south. Therefore, it is listed as one of the twelve largest wetlands in Taiwan according to the IUCN. The 206-ha Lanyang River Estuary Waterbird Reserve is included in this IBA Site.
