Bat diversity and abundance in different habitats along an elevational gradient was assessed on Mt. Kanlaon Natural Park (MKNP) from 19 May 2 June 2015 using mist netting and harp trapping methods. A total of 72 net nights and 68 trap nights as well as 65 20m x 20m circular vegetation plots were conducted. There were 608 bats captured representing 23 species, of which 8 are endemic to the Philippines. Ten bat species were added to the list of bats previously recorded in Mt. Kanlaon : Pteropus pumilus, Hipposideros ater, Hipposideros diadema, Kerivoula cf. hardwickii, Kerivoula pellucida, Murina cyclotis, Myotis cf. rufopictus, Pipistrellus sp., Rhinolophus inops, and Rhinolophus subrufus. Secondary montane forest had the highest bat diversity (H1 = 1.88). Logistic Regression Analysis and Poisson Distribution showed several variables (number of trees of specific height, canopy and subcanopy cover, elevation, number of dead trees and fruiting trees, distance from water, and mean DBH) with significant association to bat occurrence and abundance.
