The document summarizes research on mapping the metapopulation structure of tigers in Nepal using a community-based network of "Bagh Heralu", or tiger trackers. The researchers established a network of tiger trackers to assess connectivity between protected areas, determine if breeding occurs outside protected areas, and monitor tiger populations. The trackers collected data on tiger tracks, kills, and breeding evidence. Analysis identified potential dispersal corridors and three breeding areas outside protected areas that may act as sinks. The program empowered local communities and increased understanding of tiger conservation issues. Future work will expand the trackers' roles and explore source-sink dynamics to better inform conservation.
