On the banks of the palm-lined Ewaso Nyiro River, Samburu, Buffalo Springs, and Shaba Reserves lie in an arid region in the remote north of Kenya.  The wildlife in these three reserves depends on the waters of the river to survive, and many species are specially adapted to the parched conditions such as Grevy’s zebras, Somali ostriches, and gerenuks, the long-necked antelope that stand on two rear legs to reach the fresh shoots on upper tree limbs.
