According to the latest census, the number of mountain gorillas in central Africa is up by 26.3 percent since 2003. Nice work, Sigourney.
Martha Robbins, the primatologist who led the study, called it a "spectacular upsurge." Credit for the gorillas' revival is being attributed to the International Gorilla Conservation Program, which in 2003 began helping local communities develop economically so they wouldn't rely on poaching. The movie probably helped generate interest as well.
According to Robbins, this shows that "with enough effort it is possible to bring a population back from precariously small numbers." That's good news, and not just for gorillas: There are 1,939 other species considered "critically endangered."
