Anurans (frogs and toads) have high percentage of endemism in the Philippines. This study was conducted in six sampling sites of Mt. Matutum Protected Landscape (MMPL), South Cotabato to determine the species richness, diversity, and endemism of anurans. Cruising method was done at different elevations in disturbed and undisturbed sites of Mt. Matutum. Paleontological Statistics Software Package (PAST) version 3.06 was used to determine biodiversity indices and similarity index. Kruskal-Wallis test was also done. Thirteen species of anurans belonging to six families and eight genera with high percentage of endemism (76.92%) were documented. High species diversity with more or less even distribution was recorded in MMPL. Site 2, a disturbed montane forest had the highest species richness, diversity, and endemism. The Philippine endemic and vulnerable species, Oreophryne anulata, was the most abundant. Seven species of anurans are threatened (six vulnerable, one endangered) and are all endemic. Sites 3 and 6 had the highest similarity percentage (88%) as shown by the Bray-Curtis cluster analysis while Kruskal-Wallis test showed no significant difference between samples in disturbed and undisturbed sites. Conversion of forest to farmland and hunting were observed as the threats to the endemic and threatened anuran species in Mt. Matutum Protected Landscape. Results indicate the need to conserve the anurans of MMPL through the protection of habitats.
