Geography of Mauritania


Terrain shapes and bedrock

The coastal area of ​​the Atlantic consists of beach tracks, lagoons and dunes. The material transport takes place southwards by means of the Canary stream. Inside the beach is a wide coastal plain that reaches 50 m above sea level. The sedimentary deposits on the coast turn east into an upland area. Northern Mauritania is an area with many faults and insel mountains; highest reaches Kediat Idjil, 915 m above sea level. Even further to the north, the Sahara takes over with huge sand dunes with northeast-southwest extension.

The eastern part of Mauritania is part of the huge bowl-shaped inland basin el-Djouf, where the landscape can almost be described as the stone desert. Southern Mauritania belongs to the Sahel region, where plateaus and mountainous areas dominate alongside rivers that occasionally only supply water. The country’s only permanent river is the Senegal border river in the south.

Plant-and animal life

Mauritania Wildlife

Eastern Mauritania belongs to the Sahara and is vegetation-free or has desert vegetation with ephedra, some tamarisk, amaranth and grass. At the Senegal River furthest south there is a narrow tree belt with acacias and grasslands. Although the coast is also desert-like, there are some wetlands here, which are visited by resting migratory birds during parts of the year. In total, about 1,100 species of hiding-seeded plants have been noted.

There are about 60 species of mammals, including the now rare Dorcas gas cell and the endemic desert rat Gerbiʹllus mauritaʹniae. Gold shawls and spotted hyena are rare, while caracal is more widespread in the desert areas. A few elephants occasionally enter Senegal. About 275 species of birds breed and about 550 are observed, including many species of migratory birds from Europe. In the deserts, larches, stonewashes and fly hens are typical features.

Nature conservation

In 1996 Mauritania had two national parks, Diawling in the delta of the Senegal River and Banc d’Arguin on the northern Atlantic coast, as well as a couple of larger nature reserves. Banc d’Arguin is an important resting and wintering place for, among other things. ant snap, terns, flamingo and pelican.
