The park's immense savannahs, grasslands and woodlands, interspersed with gallery forests along the river banks and the swampy depressions, are home to four large mammals: the elephant, giraffe, hippopotamus and above all the white rhinoceros. Though much larger than the black rhino, it is harmless; only some 30 individuals remain.
