“Their rate of decline is quite alarming,” says Dirck Byler great ape conservation director at GWC and vice chair of the IUCN SSC Primate Specialist Group Section on Great Apes. There are only around 200,000 of them left and experts project that in the next 30-40 years, their population will decline by 80%, leaving only 40,000 wild chimps alive. Chimpanzees could once be found across the central area of Africa, within the equatorial region. The IUCN reports that there is significant overlap between Western Chimpanzee terrain and areas suitable for oil palm development in Western Africa, which is “likely to exacerbate population declines in coming years.” That’s especially true in Liberia, where 94.3 percent of areas of Western Chimp occurrence overlap with areas that might be targeted for oil palm plantations, and Sierra Leone, where there is 84.2 percent overlap. In the US, for example, around 2,000 chimpanzees are currently living in captivity. Women living near a national park in Guinea-Bissau, for instance, consider the chimpanzees themselves unfit for consumption, and blame the animals for malnutrition in their villages because of the damage they do to crops. In the west, population estimates range between 21,000 and 55,000. verus (errata version published in 2016). The main threats to the Western Chimpanzee are almost all man-made. When compared with data collected before 1994, these data suggest a catastrophic decline in ape populations in the area. Current trends indicate that African ape populations will decline by an additional 80 percent in the next 30-40 years. Habitat destruction, for development and for agriculture, also causes serious population decline. The chimpanzee is a great ape species that is native to sub-Saharan Africa, where it prefers forests and jungles. Of particular concern is the Nigeria-Cameroon chimpanzee, which has the smallest wild population at only around 6,500. CITES signatory countries are prevented from capturing, trading, or otherwise killing plant and animal species on the list. Each population faces different threats, thus a regional approach to the conservation of each subspecies is considered crucial. The majority of these can be found in Germany, where 65 bonobos are distributed among 6 zoos. Even infectious disease outbreaks that decimate the chimp’s numbers may be more frequent thanks to human activities. populations. The estimated change in the subspecies abundance, as approximated by nest encounter rate, yielded a 6% annual decline and a total decline of 80.2% over the study period from 1990 to 2014. Chimpanzee meat makes up between 1 and 3% of bushmeat in Ivory Coast markets. Additionally, these animals are highly sought to be sold and traded in the illegal pet market. The chimp’s numbers are “in the low hundreds” in Ghana, Guinea-Bissau, and Senegal, the IUCN notes, while “Côte d’Ivoire has seen a catastrophic decline of about 90% of its Chimpanzee population.”, The authors of the American Journal of Primatology study write that the IUCN plans to start updating a 2003 conservation action plan for Western Chimpanzees this year, with the intent of providing “a consensus blueprint for what is needed to save this subspecies.”. The bonobo inhabits areas south of the Congo river and the common chimpanzee can be found to the north of the Congo river. Our results show that there has been an alarming decline in chimpanzee numbers, and that urgent action is required to prevent them from disappearing entirely. Two independent assessments over the past two years have estimated that human impacts — through loss and fragmentation of habitats and populations — are likely contributing to a 2 per cent to 6 per cent decline in populations of the great apes, including chimpanzees. Their populations are currently in decline and the IUCN lists them as Endangered. As urban areas come into closer contact with chimpanzee habitats, the likelihood of contracting these diseases increases. The population of the endangered West African chimpanzees in Ivory Coast has fallen by about 90% in less than 20 years, a study has suggested. Here we assess the rate of population change for the western chimpanzee, Pan troglodytes verus, over a 24-year period. Many times, the mother is killed and sold in the urban markets as bushmeat and her baby is then sold off as a pet. The team writes that they “detected a significant negative trend” at 12 of the 20 sites. Chimpanzees could once be found across the central area of Africa, within the equatorial region. The SCNC uses a count of all nests detected Much smaller populations inhabit Ghana, Senegal, and Mali. Chimpanzee and Human Interaction. The International Union for Conservation of Nature (IUCN) has listed this species as endangered. This is followed by larger chimpanzee populations in Guinea-Bissau, Sierra Leone, Guinea, Liberia, and Nigeria. Chimpanzees are highly intelligent and social animals. Poaching is a serious problem for chimpanzee conservation. We depend on support from users like you. The common chimpanzee has a wild population size of between 150,000 and 250,000 and the bonobo is estimated to have a wild population of between 29,500 and 50,000. … Sadly, many are used in terrible lab experiments, kept in captivity, and cruelly exploited by humans in a variety of other ways. This means that in non-signatory countries, chimpanzees are still being caught and used in circuses. In other areas, this species is killed for use as folk medicine. Populations are no longer found in Gambia, Burkina Faso, Benin, or Togo. Both have the largest brains of all primates, are the most intelligent, use tools, and are the closest relatives to humans.

These animals are valued as a food source for humans. chimpanzee, including an evaluation of the change in population size over the last three decades, an update of their geographic range, and an overview of estimated current population sizes. Within these countries, chimpanzees can only be found in large tracts of virgin forests. However, in some instances, species are able to persist and co-exist with h… These circus chimpanzees are caught as babies so they can be trained from a young age and the poachers also kill the adults in the group to gain easier access to the targeted babies. Both hunting and habitat loss affect the current chimpanzee populations but also affect the future sustainability of the species. At the beginning of the 20th century, this area extended from the western regions of Tanzania and Uganda to the southern region of Senegal and chimpanzees inhabited the heavily forested areas. Our results suggest that the close approach of humans to apes, which is central to both research and tourism … Around the world, additional chimpanzee populations are being kept in captivity. So do its elephants, Activists in Malaysia call on road planners to learn the lessons of history, Road-paving project threatens a wildlife-rich reserve in Indonesia’s Papua. As these habitats become more fragmented, chimpanzee populations are forced to live in greater isolation, which results in a less diverse gene pool. The Chimpanzee Conservation Center is located in the heart of the National Park of Upper Niger within the Faranah Prefecture. We also discuss possible reasons for their decline and outline what is needed to substantially improve conservation of this subspecies. Located in the Republic of Guinea, the Chimpanzee Conservation Center (CCC) is a sanctuary created in 1997 for victims of the rampant pet trade.Once abundant in Guinea, wild chimpanzee population continue to decline and are now on the brink of extinction. According to the WWF, chimpanzee numbers have declined by 90% in the last 20-30 years in certain countries like Cote d'Ivoire. This species can still be found within its original range, however, its habitats are smaller and more fragmented than previously.

In the east, chimpanzees inhabit the western areas of Tanzania and Uganda, Rwanda, the Central African Republic, and the Democratic Republic of Congo. Because of the similarities between chimpanzees and humans, these animals are able to contract human diseases. During 1998–2000 extremely low densities of gorillas Gorilla gorilla gorilla and chimpanzees Pan troglodytes troglodytes were found in the Minkebe Forest block in north-eastern Gabon. “This also resulted in a reduced geographic range of 20% (657,600 vs. 524,100 km2).”. 'Western chimpanzee populations … Research published in the American Journal of Primatology earlier this month finds that the overall Western Chimpanzee population has declined by more than 80 percent over the past quarter century.
