Site description The Nghia Hung district has 12 km of coastline and is bordered to the west and east by the Day and Ninh Co Rivers. There are three coastal communes in the district; Ngia Trung, Nam Dien and Nghia Phuc.

Key Biodiversity During April 1994, it was estimated that more than 30,000 shorebirds were in Nghia Hung district. A high tide roost of shorebirds has been located on the southernmost offshore island: three high-tide counts were made on the island and a maximum of 1774 shorebirds were recorded during May 1996.

Non-bird biodiversity: Can also be classified as A4i for containing 2.1% of the world population of Tringa erythropus.

Protection status Nghia Hung was proposed a nature reserve by Birdlife and the Forest Inventory and Planning Institute (FIPI). This idea has the support of Nam Dinh Provincial People's Committee and Forest protection Department (FPD). Nghia Hung is not listed on any official decree related to the Special-use Forest system, however is included on a proposed list of protected areas currently being prepared by FPD and FIPI, as a 7,600 ha nature reserve.
