How they approach the work

Named approaches extracted from this org’s sources. Where others share an approach, follow it to see the full set of orgs running it.

  • Community-Led Conservation
    methodology: community-led conservation
    By empowering local communities to lead conservation efforts, we achieve more sustainable protection of endangered primates and their habitats, because local stewardship fosters long-term ecological and cultural resilience.
  • Technology-Enabled Monitoring
    methodology: technology-enabled conservation monitoring
    By integrating drone technology into forest surveillance, we improve the effectiveness and reach of primate conservation efforts, because real-time data collection enables rapid response and reduces illegal activity in critical habitats.
