The population of Gombe National Park’s chimpanzees has fallen by nearly 50 percent since the early years of research by Jane Goodall in the 1960s, raising concerns about the future of one of the world’s best-known primate populations.
From an estimated 150 chimpanzees recorded during the early years of research, the population had fallen to about 77 individuals by 2024, according to Tanzania National Parks (Tanapa).
