The only place where one can find an okapi is in the forests of northeastern Democratic Republic of Congo (DRC). Their range is limited by high montane forests to the east, a swamp forest below 500 m to the west, savanna to the north and woodland to the south.
Okapis prefer altitudes of 500 to 1,000 metres, but may venture above 1,000 metres in the eastern montane rainforests. The range of the Okapi is limited by high montane forests to the east, swamp forests below 500 metres to the west, savannas of the Sahel/Sudan to the north and open woodlands to the south. Okapis are most common in the Wamba and Epulu areas.
