Abstract:   (12541 Views)
Dinagat Islands hold most of the mineral deposits in the Philippines and have been among the largest mining contributors in the country since 1939. Aside from a massive mining industry, logging is also intensive in this group of islands potentially imperiling its remaining biodiversity. This study primarily aims to determine the species composition of terrestrial vertebrates (amphibians, reptiles, birds, mammals) in two study areas categorized as modified habitats (mining area and logging area) in the Dinagat Islands. These wildlife species are important bio-indicators as they show sensitivity of the species to anthropogenic disturbances. Suitable field survey methods were conducted for the taxa established and a quantitative analysis was performed to determine the diversity and similarity of the species between the study areas. A total of 65 species were identified in the two study areas: 33 species were exclusively identified in the mining area, 49 species were exclusively identified in the logging area, and 17 species were found in both study areas. It should be noted that among the 65 species, 41 species are either endemic to Mindanao and/or the Philippines, and two species were endemic to Dinagat Islands. This study also recorded the newly described coral snake endemic to the island, Calliophis salitan Brown, Smart, Leviton and Smith. This study indicates that although Dinagat Islands is modified by anthropogenic activities, the terrestrial vertebrate species are thriving. Intensive survey in other modified habitats in Dinagat Islands is the next-step forward to take into account existing wildlife to improve conservation decisions, planning and management on the islands.
