Bats are known to be effective pollinators and seed dispersers that aid in shaping forest ecosystems. This study was conducted using the mist netting method to determine species diversity of fruit bats in three sampling sites in Bega Watershed, Barangay Mabuhay, Prosperidad, Agusan del Sur, Philippines. One hundred eighteen individuals comprising eight bat species were documented. Four species are endemic to the country of which one species, Ptenochirus minor, is restricted to the Mindanao Faunal Region. Megaerops wetmorei was the only species recorded with vulnerable status but was present in all sampling sites. Seriation analysis using Paleontological Statistics Software showed that there is an increasing trend of species richness from sampling sites 1 to 3. Moderate diversity was observed for the whole area (H’=2.004) and site 3 was the most diverse among all sites. Cluster analysis showed that sites 2 and 3 have more similar species composition. The presence of endemic and vulnerable species suggests that Bega watershed is an area of conservation importance.
