Great apes population estimates
All great ape species have experienced considerable declines in population size and range over the past few decades. The International Union for Conservation of Nature (IUCN) Red List of Threatened Species lists all of the great apes as either Endangered or Critically Endangered and all great apes except the Mountain gorillas show decreasing population trends. Most notably, fewer than 300 Cross River gorillas are left in West Africa; as few as 2,000 Eastern Lowland gorillas remain; and it is believed that as few as 6,600 Sumatran orangutans can be found in the wild.
