Bats are integral part of the ecosystem for it plays a vital role in its stability, yet, their existence is being threatened. The study was conducted to evaluate the assemblage of bats in one of the underexplored sites of Eastern Mindanao Biodiversity Corridor. Mist-netting for a total of 189 net nights was carried out to document the species. A total of 10 species was observed.   Among these species, C. brachyotis had the highest relative abundance comprising 53% of the population. Species diversity was relatively higher in Secondary Mixed-dipterocarp (H’=1.41) compared to Dipterocarp forest (H’=1.19). The species Ptenochirus jagori and Rhinolophus subrufus were the only bats observed with aggregated dispersion pattern. Six species were endemic showing 60% endemicity. While Eonycteris robusta and Rhinolophus subrufus were the Near-threatened species recorded. Based on the results, Awasian Water Forest Reserve houses a complex assemblage of bat species with a high percentage of endemicity.
