The Center for Ecological Development and Recreation (CEDAR) is an ecotourism site comprised of natural and human-modified ecosystems in Bukidnon, Philippines. With very few existing research on the influence of human-modified ecosystems on the amphibian assemblage in the Philippines, we designed this study to evaluate amphibian assemblage in CEDAR. Using a combination of strip-transect sampling, active searching, and auditory samplings, amphibian samplings were conducted in three sites: human-modified area, dipterocarp forest, and the Dila River System. A total of 425 individuals composed of 18 species from 13 genera and 7 amphibian families were documented. The family Ceratobatrachidae was the most represented group with four species. Out of 18 species, 14 species (77.77%) were Philippine endemics suggesting a high amphibian endemism in CEDAR. In terms of conservation status, 14 out of 18 species were classified as Least Concern, and two were under the Near Threatened category. The Shannon-Weiner and Gini-Simpsons Diversity values revealed that the Human-modified area had the highest diversity value (H’= 2.032; D= 0.812) compared to the Dila River System (H’= 2.005; D= 0.862), and Dipterocarp Forest (H’= 1.264; D= 0.553). Surprisingly, the human-modified area in CEDAR was found to be the surrogate habitat of many anuran species, in particular, a number of generalist species whilst some specialist species were restricted in the natural habitat like the Dipterocarp Forest and Dila River System. Unfortunately, the high amphibian diversity in the human-modified area requires further field studies, hence, additional samplings are recommended. Also, wildlife evaluation and monitoring should be carried-out in CEDAR to facilitate the conservation of amphibian populations and their natural habitats in this area.
