Mauritania - Flora and fauna
In the desert there are some cacti and related species; oases support relatively luxuriant growth, notably date palms. In the south are grasses and trees common to the savanna regions, particularly the baobab tree, but also palms and acacias. The far south, in the Senegal River valley, has willows, jujube, and acacias. Lions, panthers, jackals, crocodiles, hippopotami, hyenas, cheetahs, otters, and monkeys survive in the south; in the north there are antelopes, wild sheep, ostriches and other large birds, and ducks.
