Cu Lao Cham Marine Park also known as Cham Islands Biosphere Reserve is part of the eight islets of the Chàm Islands, located in the South China Sea under the administration of Tân Hiệp Commune and Hội An town, in Quảng Nam Province, Vietnam.

[1][2] The eco system also includes the ancient Hội An, which is 20 kilometres (12 mi) away from the islands, a UNESCO World Heritage Site.

The objective of declaring the islands as Biosphere Reserve is to adopt different approaches of integrated management of terrestrial, freshwater, coastal and marine resources and biodiversity.

The uncluttered, least inhabited island group, with their steep rock slopes, sea waves and rich vegetation has been given the soubriquet “unpolished sapphires”.

[3] The swamps and marshes of maritime-marsh origin evolved as a result of receding seas in ancient times (about 2000 years old).

They are also found in stretches along the coast, south of the Thu Bon River that runs past Trung Phuong (Duy Xuyen district).

[9] The most important terrestrial fauna of the islands are the salanganes, also called swallows, whose nests have been a source of revenue to the local people.

[13] Mỹ Sơn was their religious centre at the height of a Hindu empire, which ruled from Da Nang, which was the capital of Champa in the past.

The issues proposed to be addressed are: to conserve biodiversity, cultural diversity and natural resources with due regard to cultural values; conserve anthropogenic ecosystems; improve the natural environment; create corridors of ecological zones; restore and rehabilitate environmentally degraded areas.

Integrated monitoring is an essential feature to assess and evaluate all studies to evolve appropriate action plans for the biosphere conservation and preservation.
