Chimpanzees are members of the great ape family, which includes bonobos, gorillas, orangutans, and humans. They inhabit 21 African countries and live in the greatest concentrations in rainforests along the equator.
Free-living chimpanzee populations are rapidly decreasing due to deforestation and the illegal bushmeat trade, for which chimpanzees and other non-domesticated animals are hunted and killed for human consumption. One to two million chimpanzees lived in Africa in 1900, while only about 150,000 free-living chimpanzees exist today, making them highly endangered.
Chimpanzees are genetically very similar to humans, sharing 98.76% of their genetic material. In fact, chimpanzees are more closely related to humans than they are to gorillas. Unfortunately, chimpanzees pay a high price for being our closest relatives. In captivity, they are subjected to various forms of exploitation and abuse.
According to Project Chimp Care, there are currently 1,822 chimpanzees living in the United States. Of that number, 797 chimpanzees are in biomedical research facilities, and 65 are used for entertainment or kept as pets. There are 262 chimpanzees in AZA accredited zoos, 524 in sanctuaries that belong to the North American Primate Sanctuary Alliance, and 174 living in unaccredited facilities.
At Chimpanzee Sanctuary Northwest (CSNW), we are working to ensure that the number of chimpanzees exploited in biomedical research and entertainment will decrease as more sanctuary space is created. At CSNW, we believe that the physical, psychological, and emotional needs of the chimpanzees come first.
With a thorough understanding of chimpanzee behavior, caregivers can interpret the needs and wants of the chimpanzees they care for, and even use chimpanzee behaviors to facilitate better communication and enrich chimpanzee-human interactions.
