In the 19th c. the Pig-Tailed Baboon or Macaque began its decline in population due the loss of its habitats in Sundaland, southern Thailand, Malaysia, and Indonesia. Its equatorial tropical rainforests began to be replaced with the discovery of palm oil which only grows in this narrow climate. This image of the Pig-Tailed Baboon was originally an illustration by the 19th c. artist George Shaw and the background is taken from an illustration of a 19th c. palm oil plantation, artist unknown.
