Site description Banc d’Arguin National Park was established in 1976 and protects 40% of the Mauritanian coastline, between Nouakchott and Nouâdhibou, on the northern the Mauritanian coast. The National Park includes shallow open sea (less than 5 m) and seagrass beds, intertidal flats, channels and creeks, as well as coastal desert habitats. Within the park the maximum tidal range is 2.0 m, while the average is between 1.2 and 1.7 m. The total area of intertidal mudflats is some 55,000 ha and there are between 60,000–80,000 ha of seagrass beds. Coastal vegetation includes clumps of mangrove Avicennia africana as well as the grass Spartina maritima and species of Chenopodiaceae. The terrestrial part of the reserve includes areas of Saharan vegetation, principally the tree species Acacia tortilis, Balanites aegyptiaca, Maerua crassifolia and Capparis decidua, and the herbaceous species Panicum turgidum, Cassia italica, Pergularia tomentosa and Heliotropium bacciferum. The dunes on the southern fringe of the park are dominated by Stipagrostis pungens, Cornulaca monacantha, Euphorbia balsamifera and Calligonum comosum. A total of 190 plant species have been recorded in the park. Adjacent to the park lies one of the world’s richest fishing grounds, resulting from upwellings off Râs Nouâdhibou and Râs Timirist and the prevalence of seagrass beds and other productive shallow-water benthic habitats.
