Ajai Wildlife Reserve is found in north-eastern Uganda (Arua District) on the western banks of the Nile. The reserve gained world attention when Theodore Roosevelt, a former American president visited in 1910 on a hunting expedition. Ajai Wildlife reserve is located in an area with higher elevation but is relatively small (166 sq km). The reserve is characterized by a prominent island that is surrounded by Savannah and swamps. This seasonal swamp is fed by the river Acha and Ala. During the rainy season, the swamp gets completely flooded cutting off the island from the outside world. This explains why animals continue to survive within the Island close a growing human population.
