PLCN and partners developed an application for smartphones (the Prey Lang app), making it easy for local patrols to geo-reference, document, and upload information about forest resources, threatened biodiversity, and illegal activities. The data is used to document the importance of the forest to local livelihoods, international biodiversity conservation, and to report illegal activities to the authorities.

The Prey Lang app enables systematic data collection during patrols on valuable resources and the effects of illegal activities on biodiversity and the local livelihoods. Documentation is substantiated with GPS coordinates, photos and audio information.

The collected data is uploaded to a database, which can be accessed in Cambodia and by the University of Copenhagen. A database manager in coordination with students and researchers compile reports on the status of Prey Lang which are released at press conferences and published on the internet and via social media. Recently, a climate component has been added, enabling the patrollers to record signs of climate change and climate mitigation actions. In the latest version of the app a component to enhance the security of the patrollers was added. The new functionality allows PLCN members to report threats and instances of violence.
