This talk focuses on a community-based biodiversity monitoring system in the Sanjiangyuan Region, explaining how we design and deploy over 300 camera traps and how over 300 local monitors assist us in collecting data. We will also cover our methods for camera management and the incentive mechanisms used to support and motivate local monitors. The presentation will also touch upon our use of various other monitoring methods to survey ungulates and birds, as we attempt to build a comprehensive understanding of the entire ecosystem.
