The Banc d'Arguin National Park (, ) of Bay of Arguin lies in Western Africa on the west coast of Mauritania between Nouakchott and Nouadhibou and is the former mouth of the Tamanrasset River. The World Heritage Site is a major site for migratory birds and breeding birds, including flamingos, pelicans and terns. Much of the breeding is on sand banks including the islands of Tidra, Niroumi, Nair, Kijji and Arguim. The surrounding waters are some of the richest fishing waters in western Africa and serve as nesting grounds for the entire western region. The Banc d'Arguin National Park is a Nature reserve that was established in 1976 to protect both the natural resources and the valuable fisheries, which makes a significant contribution to the national economy, as well as scientifically and aesthetically valuable geological sites, in the interests of and for the recreation of the general public. The park's vast expanses of mudflats provide a home for over one million migrant shorebirds from northern Europe, Siberia and Greenland. The region's mild climate and absence of human disturbance makes the park one of the most important sites in the world for these species. The nesting bird population is also noted for its great numbers and diversity. Between 25,000 and 40,000 pairs belonging to 15 species, making the largest colonies of water birds in West Africa. Conservation The extensive intertidal flats of Parc National du Banc d’Arguin shelters on the most pristine seagrass beds on earth. Human impact is still at its minimum compared to the other intertidal systems along the East Atlantic Flyway. Only small indigenous community is allowed to fish in the Park boundaries using relatively primitive techniques and tools. No motorized boats are permitted in the area. Over the last decade, however, the international shark/ray market made its way to PNBA. Locals starts to target these species although it is not allowed. It is perhaps the most challenging issue facing the conservation of the park. People The local population comprises about 500 or so Imraguen tribesmen that live in seven villages within the park. They base their economy on subsistence fishing using traditional methods. Fauna The park is host to one of the world's most diversified communities of nesting piscivorous birds in the world. At least 108 bird species have been recorded, representing both Palaearctic and Afrotropical realms. Wintering shorebirds number over three million and include greater flamingo
