An Inventory of Bats (Chiroptera) in Mount Musuan, Maramag, Bukidnon, Philippines Conducted Between 2013 and 2023

Abstract

Bats play a crucial role in the ecosystem. However, their richness and abundance is declining, especially in tropical countries like the Philippines. This study was conducted to monitor and compare the species richness, abundance and status of bats in Mount Musuan, Maramag Bukidnon over 3 sampling periods between 2013 and 2023. Three sampling sites were established in the study area. Only the mist netting strategy was applied to capture bats, which were identified through morphometric measurements and field guide. The IUCN Red List was referred to determine the conservation statuses of the recorded bats. A total of 11 species belonging to 4 families were recorded: Megadermatidae, Pteropodidae, Rhinolophidae and Vespertillionidae. The highest number of individuals captured were Ptenochirus jagori (186), Cynopterus brachyotis (113) and Miniopterus schreibersi (53). Of the bats collected, 82% (9) were classified as Least Concern, 9% (1) as Endangered and 9% (1) as Near Threatened. Out of 11 species, 7 (64%) species were Philippine endemic species. This study contributes important information to the existing knowledge of bats in the region, highlighting their abundance and significance in local wildlife. The results can be used to inform conservation strategies of these species.
