The precise landscape boundaries remain unclear and are currently a major topic of discussion at a time when the Ministry of Environment is establishing the Prey Lang Wildlife Sanctuary.2 For more information, refer to Prey Lang Protection. It is challenging for people to advocate for the protection of a land without defined borders.

In addition, roads that have been constructed since 2008 have made remote places such as Prey Lang accessible for people and companies.3 This has led to increasing resource extraction, which was already happening extensively throughout Prey Lang. The forest is increasingly being opened up, which causes tremendous changes and poses questions for the future of its wildlife, indigenous people and habitats.

Indigenous people and growing public awareness

Prey Lang is mostly home to the Kuy indigenous people. It is a place of much traditional significance for Cambodians, contributing to the raising of public awareness for its protection. Indigenous people have been living in the forest for generations, and the place is of the utmost cultural importance.4 It is estimated that around 700,000 people are living within 10km of Prey Lang.5

The Prey Lang Community Network recently gained international attention, and was acknowledged and rewarded during the COP21 environmental summit in 2015.6 The network contributes to the forest’s protection by reporting illegal activities.7
