The Ajai Wildlife Reserve is a small conservation protected area in North Western Uganda dominated by a large island surrounded by seasonally flooded swamps and wooded savanna.
Ajai lies on the western bank of the White Nile, approximately east of Arua.
Historically, Ajai Game Reserve was only declared in limited area of 4 square Kilometers as a Game Sanctuary by the British Government in 1937. Prior to this, the former President Theodore Roosevelt of the United States of America (USA) had visited in King Ajai's palace during his African expedition in 1910. During President Roosevelt's expedition he hunted several White Rhino's which drastically reduced the number of White Rhinos in the reserve. Five years later, approximately 1915, King Ajai started supervising hunting in the area. Ajai's efforts later led to the declaration of a controlled area about 4 square kilometers by the government in 1937. The area declared a sanctuary was part of King Ajai's palace and didn't extend beyond.
Northern white rhinoceros had historically been plentiful in northern Uganda west of the Nile River. In the face of rising concerns of over-hunting in the 1920's, Uganda introduced licensing requirements for hunting the species. As the population continued to decline, with estimates dropping from 150 to 80 in just three years, conservation efforts increased. The Uganda Game Department relocated 15 rhinos from the territory of present-day Obongi District southwards to Murchison Falls National Park in 1961 and 1964. In 1965 the Game Department gazetted the Ajai Game Reserve, aiming to protect the dwindling resident rhino population, then estimated at around 50 animals. In 1962 the nascent World Wildlife Fund made its first rhino conservation grant, supporting the East African Wild Life Society with $56,000 to combat poaching and smuggling of rhino horn from the West Nile and Madi districts, including in Ajai.
Conservation enforcement was subordinated to power struggles of successive dictatorships beginning in 1966, especially the Uganda-Tanzania War. This led wildlife populations all around the newly-independent Uganda to collapse under the pressures of land-use conflict and poaching. The rhino population of Ajai was extinguished in 1979.
In 2002 Uganda Wildlife Authority began efforts to enlarge the boundaries of the reserve with a view of later re-introducing the White Rhino's into the reserve following years of the surviving Rhinos being kept at the Ziwa Rhino Sanctuary. In 2022 the UWA Board of Trustees voted to move animals from Ziwa to Ajai.
In 2008 the Uganda Wildlife Authority contracted with Uganda Wildlife Safaris Ltd, a private hunting and photographic tour operator, to develop the reserve for tourism. By 2020 UWA cancelled the concession as the vendor had failed to deliver.
The reserve supports around 35 kilometers of papyrus swamp along with grassy floodplains and Savannah woodland. Large mammals present include leopard, Ugandan kob, sitatunga, hippo, black-and-white colobus and warthog.
In January 2026, the first four of a planned 20 southern white rhinos from the Ziwa Rhino Sanctuary were relocated to Ajai Wildlife Reserve. An area of was prepared to support and protect the rhinos, beginning in August 2025. If and when the first batch of relocatees are successfully acclimatized, the remaining 16 animals will also be relocated.
To get to Ajai from Arua, follow the surfaced Packwach Road south for 15 kilometers to Olevu, then branch left on to a 40 kilometer dirt road running east to the reserve.
