The Apsara National Authority (ANA), responsible for managing Cambodia’s Angkor Archeological Park, has reported that the increasing number of monkeys living within the park have begun posing a risk to visitors and environmental hygiene. Domesticated monkeys have replaced their wild counterparts, resulting in hundreds of them living within the park who have now become accustomed to people and rely on human feeding. ANA has urged tourists to avoid feeding the monkeys for the purpose of photography to allow them to naturally sustain themselves and cease putting both guests and the park’s infrastructure at risk. The Angkor Archeological Park is the most visited South-East Asian tourist destination, with approximately 401 square kilometres of land inscribed on the World Heritage List by Unesco in 1992.
