Why Are Chimpanzees Endangered

Why Are Chimpanzees Endangered?

In the lush, verdant heart of Eastern and Central Africa’s forests, the chimpanzee (Pan troglodytes) thrives as one of our closest living relatives, sharing approximately 98.8% of our DNA. Chimpanzees, also known as “chimps,” are intelligent primates that exhibit complex behaviors such as tool use, intricate social structures, and a wide range of emotions, reflecting a profound connection to humans. Despite their remarkable adaptability, chimpanzees are currently classified as endangered, facing many threats that jeopardize their survival, such as wildlife crime, as well as the violent bushmeat and illicit exotic pet trade.

Chimpanzees are part of the Great Ape family which also includes gorillas and orangutans. Their living cousins also include bonobos, which were previously called pygmy chimpanzees until it was revealed that they had their own independent lineage and created completely different societies. There are four recognized subspecies of chimpanzees, each with distinct geographic distributions and slight genetic variations.

Western Chimpanzee (Pan troglodytes verus): Found in West Africa in Guinea, Sierra Leone, Liberia, Côte d’Ivoire, and Mali, this subspecies is one of the most critically endangered. This is mainly due to hunting, habitat destruction, and fragmented populations. Notably, some groups use primitive spears to hunt small prey.

Central Chimpanzee (Pan troglodytes troglodytes): The central chimpanzee is the most widespread subspecies, found in Gabon, Cameroon, the Republic of Congo, and Equatorial Guinea. These primates are skilled tool users and are among the best-protected chimpanzees due to conservation efforts in Gabon.

Eastern Chimpanzee (Pan troglodytes schweinfurthii): Native to Uganda, Rwanda, Tanzania, and the Democratic Republic of Congo (DRC), this Eastern chimpanzee is famous due to Dr. Jane Goodall’s research in Gombe Stream National Park. These chimpanzees display sophisticated hunting behaviors and complex social structures.

Nigeria-Cameroon Chimpanzee (Pan troglodytes ellioti): This is the rarest subspecies, found only in Nigeria and Cameroon. With fewer than 9,000 individuals remaining, they are highly endangered due to habitat fragmentation and hunting.

While these subspecies share many behavioral and genetic traits, their populations face varying degrees of risk. Despite their adaptability, all chimpanzee subspecies face serious threats, pushing them closer to extinction. Understanding these threats is the first step in ensuring their survival.

Why Are Chimpanzees Endangered?

Chimpanzee populations have declined dramatically due to multiple factors, most of which are linked to human activity. The main threats include;

Habitat Loss and Fragmentation

One of the biggest threats to chimpanzees is habitat destruction. Most of Africa’s forests, which have been home to chimpanzees for thousands of years, are rapidly disappearing due to deforestation, agricultural expansion, logging, and infrastructure development. As human populations grow, more land is being cleared for farming, settlements, and roads, pushing chimpanzees into smaller, isolated pockets of forest.

In countries like Uganda, the Democratic Republic of Congo, and Côte d’Ivoire, vast areas of forest have been cleared to make way for cash crops, illegal logging, and charcoal production, stripping forests bare and leaving chimpanzees with fewer trees for shelter and food. As a result, these primates are forced into dangerous interactions with humans, often raiding farms for food, which leads to human-wildlife conflicts.

However, African governments have worked to combat habitat loss by working on reforestation projects, protected area expansion, and habitat corridors to reconnect fragmented populations. Organizations like the Jane Goodall Institute are engaging local communities in sustainable farming and forest restoration efforts, ensuring that both people and chimpanzees can thrive.

Poaching for Bush Meat

In parts of Central and West Africa, chimpanzees are hunted for their meat, a practice that has been devastating their populations. Bushmeat is often seen as a luxury item, particularly in urban markets, where it is sold at high prices. The bushmeat trade not only affects chimpanzees but also contributes to the spread of diseases. Consuming primate meat has been linked to the transmission of viruses such as HIV and Ebola, both of which have origins in great apes. Despite this, the demand remains high, driven by poverty, lack of alternative protein sources, and weak law enforcement.

However, many conservation groups and governments have implemented stricter anti-poaching laws and increased patrols in national parks and reserves to mitigate this threat. Rescue centers like Ngamba Island Chimpanzee Sanctuary in Uganda take in orphaned chimpanzees that have been rescued from the bushmeat trade, providing them with lifelong care.

The Illegal Pet Trade

The illegal pet trade is another major threat to chimpanzees in Africa. Here, young chimpanzees are often captured and sold to private collectors, circuses, or roadside zoos, where they are subjected to isolation and mistreatment. Moreover, for every baby chimpanzee that ends up in captivity, several adults are killed, as mothers and other group members will fight to protect their young.

To alleviate this malpractice, organizations like Interpol and the Convention on International Trade in Endangered Species (CITES) are actively working to dismantle trafficking networks, while rescue centers such as the Tchimpounga Chimpanzee Rehabilitation Center in the Republic of Congo provide sanctuary for rescued individuals. Education campaigns are also helping to raise awareness about the ethical and legal consequences of keeping primates as pets.

Exposure to Human Diseases

One of the less visible but equally devastating threats to chimpanzees is their susceptibility to human diseases. Because they share nearly 98% of their DNA with humans, they are highly vulnerable to many of the same illnesses that affect humans. Illnesses like common colds, respiratory infections, and tuberculosis can spread from humans to chimpanzees, often with fatal consequences.

Ebola is one of the deadliest threats, with numerous outbreaks decimating entire populations of chimpanzees and gorillas in Central Africa, for instance. Moreover, while chimpanzee trekking tourism is beneficial for conservation funding, it also increases the risk of disease transmission from humans to wild chimpanzees.

To alleviate this, conservationists have implemented strict health protocols for visitors, including face masks, hand sanitation, and maintaining a safe distance from chimpanzees. Scientists are also working on vaccines for great apes to protect them from Ebola and other infectious diseases.

Where Can I See Chimpanzees in Africa?

Despite their endangered status, there are still places where you can observe chimpanzees in the wild. Responsible tourism plays a crucial role in conservation by funding protection efforts and promoting awareness. Some of the best places for chimpanzee trekking include:

1. Kibale Forest National Park, Uganda

Kibale Forest National Park is widely regarded as the best place for chimpanzee trekking in Africa. With the highest concentration of chimpanzees in Uganda, visitors have over a 95% chance of encountering them on chimpanzee treks. Located in western Uganda, the park is home to 13 primate species, including red colobus monkeys and L’Hoest’s monkeys, making it a must-visit destination for primate lovers.

Chimpanzee trekking in Kibale involves small guided groups venturing into the forest in search of habituated troops. For a more immersive experience, the Chimpanzee Habituation Experience allows visitors to spend a full day following a chimpanzee troop as they go about their daily routines.

Other places to see chimpanzees in Uganda include Budongo Forest, adjacent to Murchison Falls National Park, Kyambura Gorge in Queen Elizabeth National Park, and Ngamba Island Chimpanzee Sanctuary.

2. Mahale Mountains National Park, Tanzania

Located in western Tanzania, along Lake Tanganyika, Mahale Mountains National Park is one of the most breathtaking places to see wild chimpanzees. Unlike other parks, Mahale offers a pristine, remote setting, accessible only by boat or light aircraft. The experience of trekking through misty forests, with the backdrop of crystal-clear Lake Tanganyika, makes it an unforgettable adventure.

The chimpanzees here are well-habituated, thanks to decades of research started by Japanese primatologists in the 1960s. The trek through Mahale’s dense forests is demanding, but the reward of sitting among a troop of chimpanzees in their natural environment is well worth the effort.

Other places to see chimpanzees in Tanzania include Gombe Stream National Park (made famous by Dr. Jane Goodall’s groundbreaking research)

3. Nyungwe Forest National Park, Rwanda

Nyungwe Forest is one of Africa’s most ancient rainforests, boasting an incredible diversity of flora and fauna. Located southwest of Rwanda, the park is home to two habituated chimpanzee groups and 12 other primate species, including Ruwenzori colobus and golden monkeys.

Chimp trekking in Nyungwe starts early in the morning and involves navigating through lush, mountainous terrain. While sightings are not always guaranteed, the experience of trekking through this biodiverse and bird-rich forest is rewarding in itself.

4. Taï National Park, Côte d’Ivoire

Taï National Park, located in Western Côte d’Ivoire, is one of the last remaining primary rainforests in West Africa and home to one of the largest remaining populations of wild chimpanzees. The chimpanzees in Taï are well studied, thanks to research that has been ongoing since the 1970s.

What makes Taï unique is its highly social and tool-using chimpanzee communities. Researchers have documented chimpanzees using sticks to fish for termites, cracking nuts with stones, and even engaging in complex social behaviors. Since Taï is less touristy compared to other chimpanzee destinations, visitors can enjoy a more exclusive and immersive experience in the wild.

5. Loango National Park, Gabon

Loango National Park is one of Africa’s most unique wildlife destinations. It is famous for its “surfing hippos,” elephants walking on the beach, and chimpanzees living in coastal forests. The Loango Chimpanzee Project, a long-term research initiative, is working on habituating the chimpanzees in the park for eco-tourism.

Seeing chimpanzees here is not yet as easy as in Uganda or Tanzania, but for adventurous travelers looking for a wild and remote experience, Loango is an excellent choice.

6. Senegal & Guinea

Unlike forest chimpanzees, the Fongoli chimpanzees of Senegal and Guinea have adapted to life in a savanna environment. They are famous for their tool use, including sharpening sticks to hunt small animals – a behavior rarely seen in other chimpanzee groups.

This region offers a unique opportunity to see chimpanzees in a completely different habitat, living in dry, open landscapes rather than dense forests. However, due to their semi-wild status and ongoing research efforts, access for tourists is limited.

What to Expect on a Chimpanzee Trekking Safari?

Chimpanzee trekking is an unforgettable experience that brings visitors face-to-face with one of our closest relatives. Here’s what you can expect:

The Chimpanzee Trek: Chimpanzee trekking usually involves hiking through dense forests, guided by experienced rangers who track the primates based on vocalizations and nesting sites. The experience starts with a briefing at the park headquarters, where visitors are taken through rules and regulations for trekking. After this, visitors are assigned a chimp troop to track, and off you go! The trek can last anywhere from 30 minutes to several hours, depending on where the chimpanzees are located.

The Encounter: Once you locate a chimpanzee group, you will have one hour to observe them from a safe distance. During this time, you may see them feeding, grooming, playing, or even using tools – behaviors that highlight their intelligence. You may record videos and take pictures of the primates as instructed by the rangers and guides. After the encounter with the chimps, you will trek back to the starting point and be awarded a certificate of participation.

Rules and Guidelines which include;

• Maintain a distance of at least 7 meters from the chimpanzees.
• No flash photography is allowed.
• Visitors must be at least 15 years old to trek with chimpanzees.
• Avoid littering the park
• Avoid flash photography while taking photos of the chimps
• Health precautions (such as wearing masks) may be required to prevent disease transmission.

Chimpanzees are remarkable creatures that deserve our protection. As deforestation, poaching, and disease continue to threaten their existence, it is crucial to support conservation efforts. This can be done by: visiting protected areas and supporting eco-tourism, donating to conservation organizations such as the Jane Goodall Institute and the World Wildlife Fund (WWF), to name a few.  By taking action today, we can ensure that future generations will continue to share the world with these extraordinary primates.
