Somewhat adequate answer: In 1986, Jane attended a conference in Chicago (organized around the release of her work, Chimpanzees of Gombe: Patterns of Behavior) and one of the consecutive speakers showed the extent of habitat destruction across Africa, and the effect it had on wild chimps. *Jane left field work in Gombe so that she could focus conserving the Chimpanzees.* I’m sorry if this doesn’t help, it’s my first answer.
