Bili-Uere Hunting Domain
One of DRC's largest protected areas, Bili-Uere spans a savanna-forest mosaic on the Central African Republic border, known for unusually large-bodied, tool-using chimpanzees.
A vast northern frontier for elephants and unusual chimpanzees
Bili-Uere Hunting Domain covers roughly 32,748 km² in Bas-Uele Province, bounded to the north by the Bomu Hunting Reserve and Bomu Wildlife Reserve along the Mbomou River, which forms the border with the Central African Republic.
Designated in 1974, Bili-Uere sits within a savanna-forest transition zone that has drawn scientific attention since the mid-2000s for its population of unusually large-bodied chimpanzees, observed using tools in distinctive ways and reportedly howling at night, sparking early speculation about a new great ape before genetic studies confirmed them as an unusual chimpanzee population.
Since 2005, the area has been recognised as a key site for chimpanzee conservation in northern DRC, alongside populations of forest and savanna elephants moving through the region's mixed habitat.
Bili-Uere remains one of DRC's most remote and least-visited protected areas; pair this guide with our Garamba National Park page for the more accessible savanna park elsewhere in the country's north-east.
What makes Bili-Uere distinct
Bili-Uere's savanna-forest mosaic supports wildlife adapted to one of DRC's most distinctive northern ecosystems.
Bili chimpanzees
An unusually large-bodied chimpanzee population here drew scientific attention for distinctive tool use and behaviour.
Forest and savanna elephants
Both elephant types move through Bili-Uere's mixed habitat, reflecting its position on the ecological transition zone.
Savanna-forest mosaic
The reserve's landscape shifts between open grassland and forest, supporting species from both habitat types.
Mbomou River border wildlife
The river border with the Central African Republic shapes a distinct riverine ecosystem within the reserve.
Connected protected area network
Bili-Uere adjoins the Bomu Hunting Reserve and Bomu Wildlife Reserve, extending habitat connectivity along the border.
Under-surveyed biodiversity
As one of DRC's most remote reserves, Bili-Uere likely holds species and populations still undocumented by science.
What visiting Bili-Uere Hunting Domain involves
Bili-Uere is among DRC's most remote protected areas, with any visit requiring extensive advance planning.
Coordinate with ICCN and conservation partners
Given the reserve's remoteness, any visit begins with direct coordination well in advance.
Travel to a Bas-Uele access point
Routes typically approach via regional towns in Bas-Uele Province, depending on current road conditions.
Overland travel to the reserve boundary
Onward travel into Bili-Uere itself requires significant overland travel given minimal infrastructure.
Research and conservation-focused activities
Most current access supports chimpanzee research and conservation monitoring rather than conventional tourism.
Return via the same access route
Departures retrace the route back to the nearest regional hub.
A remote frontier still being scientifically understood
Bili-Uere's remoteness has both protected and complicated its conservation: the area has faced less development pressure than more accessible parks, but this same isolation has limited ranger presence and long-term wildlife monitoring.
Since 2005, growing scientific interest in the Bili chimpanzee population has helped elevate the area's conservation profile, supporting the case for stronger long-term protection of this savanna-forest mosaic. See our travel guide for current conditions.
Planning questions, answered
What is unusual about Bili-Uere's chimpanzees?
The reserve's chimpanzee population is unusually large-bodied and displays distinctive tool-use and vocal behaviour that drew early scientific speculation before genetic studies confirmed them as chimpanzees.
How large is Bili-Uere Hunting Domain?
Approximately 32,748 km², making it one of DRC's largest protected areas.
Where is Bili-Uere located?
In Bas-Uele Province in northern DRC, bordered by the Mbomou River and the Central African Republic to the north.
Is Bili-Uere developed for tourism?
No. It remains one of DRC's most remote and least-visited protected areas, with access primarily supporting research and conservation work.
What other protected areas border Bili-Uere?
The Bomu Hunting Reserve and Bomu Wildlife Reserve adjoin it to the north along the Mbomou River.
