Chimpanzees, our closest living relatives, share about 98% of their DNA with humans. This strong genetic connection has driven significant interest in their conservation. Unfortunately, their population has been declining due to habitat loss, poaching, and disease. Chimpanzees are found in the forests and savannas of central and West Africa, ranging from Senegal in the west to Tanzania in the east. They inhabit diverse environments including tropical rainforests, woodlands, and grassland-forest mosaics. This article provides an overview of the chimpanzee population by country, highlighting the subspecies, the countries with the most significant populations, the historical population decline, and conservation efforts.
Chimpanzee Population by Subspecies
Chimpanzees are divided into four subspecies, each occupying distinct geographical regions in Africa:
- Central Chimpanzee: Found primarily in Central Africa, including countries like Gabon, Cameroon, Republic of Congo, and the Democratic Republic of Congo (DRC). This subspecies has the largest population among the four, with an estimated 115,000 individuals.
- Western Chimpanzee: Inhabits West Africa, including Guinea, Sierra Leone, Liberia, Côte d’Ivoire, and Ghana. The Western chimpanzee is critically endangered due to extensive habitat fragmentation and hunting, with an estimated population of 21,000 to 55,000 individuals.
- Nigeria-Cameroon Chimpanzee: Located in Nigeria and Cameroon, north of the Sanaga River. It is the least numerous subspecies, with fewer than 6,500 individuals remaining.
- Eastern Chimpanzee: Found in East Africa, including Uganda, Rwanda, Burundi, Tanzania, and the eastern DRC. This subspecies has suffered significant declines but still has sizeable populations in some regions, estimated at 50,000 to 80,000 individuals.
Countries with Most Chimpanzees
- DR Congo: The DRC is home to the largest population of Eastern chimpanzees, with an estimated 35,000 to 65,000 individuals. The vast and dense forests of the DRC provide a crucial habitat for these chimpanzees. However, the country faces significant challenges, including deforestation, mining, and poaching. Conservation efforts are complicated by political instability and limited resources, but organizations like the Jane Goodall Institute and WWF are actively working to protect these primates.
- Republic of Congo: The Republic of Congo supports approximately 45,000 Central chimpanzees. The country has established several conservation areas, such as the Nouabalé-Ndoki National Park, which is crucial for chimpanzee protection. Despite these efforts, illegal logging and hunting continue to threaten their habitat. Conservation initiatives focus on strengthening law enforcement and community engagement to mitigate these threats.
- Gabon: Gabon hosts around 35,000 Central chimpanzees. The country’s commitment to conservation is evident in its extensive network of national parks, which cover about 11% of its land area. Gabon’s forests remain relatively intact, providing a haven for chimpanzees. However, the threat of illegal hunting persists, necessitating ongoing conservation efforts and international support to ensure the survival of these populations.
- Cameroon: Cameroon is home to around 20,000 Central chimpanzees and the critically endangered Nigeria-Cameroon chimpanzee. The country’s conservation efforts focus on protecting habitats and reducing human-chimpanzee conflicts. National parks like Korup and Campo Ma’an are vital for chimpanzee conservation. However, habitat loss due to agriculture and logging, along with poaching, remain significant threats.
- Guinea: Guinea has an estimated 17,000 Western chimpanzees, making it one of the most important countries for this subspecies. The Fouta Djallon region is a key habitat for these chimpanzees. Unfortunately, Guinea faces challenges such as habitat destruction due to mining and agriculture, as well as human-wildlife conflict. Conservation strategies include habitat protection, community-based conservation programs, and anti-poaching efforts.

Chimpanzee Population Decline
Chimpanzee populations have seen a dramatic decline over the past century. Here is an estimated population trend from 1900 to 2030:
The sharp decline in chimpanzee populations can be attributed to several factors:
- Habitat Loss: Deforestation for agriculture, logging, and infrastructure development has significantly reduced available habitats for chimpanzees.
- Poaching: Chimpanzees are hunted for bushmeat, and infants are often captured for the illegal pet trade.
- Disease: Diseases like Ebola and respiratory infections have devastated chimpanzee populations.
Conservation Efforts
Conservation efforts are critical to reversing the decline in chimpanzee populations. Various organizations and governments are working tirelessly to protect these primates. Key strategies include:
- Protected Areas: Establishing and managing national parks and reserves to provide safe habitats for chimpanzees.
- Anti-Poaching Initiatives: Strengthening law enforcement to combat poaching and illegal wildlife trade.
- Community Engagement: Involving local communities in conservation efforts through education and sustainable livelihood programs.
- Research and Monitoring: Conducting scientific research to monitor chimpanzee populations and understand their behavior and ecology.
- International Support: Collaboration between international organizations, governments, and NGOs to fund and implement conservation programs.
The future of chimpanzees depends on sustained conservation efforts. By understanding their distribution and the challenges they face, we can develop more effective strategies to protect these incredible creatures. It is imperative that we continue to support and expand these efforts to ensure that chimpanzees thrive for generations to come.
