Study area and water sources within the central region of Etosha national park, Namibia. The zebra live in the west of this region, where water sources are scarce throughout the wet season (left polygon). Okon in the north-east part of the polygon is salty and with an abundance of predators. The majority of the zebra migrate in the dry season to the east, and all of them return to the west at the beginning of the wet season.
