Don Chao Poo Forest is a protected area that has been home to a group of long-tailed macaques for hundreds of years. The people of Phana believe that the monkeys are the « children » of Chao Poo, the ancestral guardian spirit of the forest and of the people of Phana.
The Phana Monkey Project (aka Phana Macaque Project) was set up in 2011 by Pensri Mahanil Whiting and her husband Lawrence Whiting after they retired to Phana where Pensri was born. Pensri and Lawrence had become aware that the monkey population was increasing rapidly while the area of forest available as a food source had shrunk. The Phana Monkey Project seeks to draw attention to this situation and the consequences it might have for the relationship between humans and monkeys in Phana.
