Chimpanzee, gorilla, and orangutan sanctuaries provide refuge for animals from the pet trade and bushmeat industry; welfare standards matter.
Great ape sanctuaries house animals with severe trauma histories requiring expert behavioral rehabilitation. Introducing traumatized animals to social groups requires careful management to prevent aggression. Space requirements for chimpanzee troops are enormous — forested enclosures of several hectares are necessary for full behavioral expression. Long-term funding for decades of care is a fundamental sanctuary welfare requirement.
