説明

<p>To support the needs of the booming ecotourism of Bohol province, construction of an international airport across four island villages was to commence in the latter part of 2013. The mega structure would reduce into concrete some 233 hectares of natural habitat and displace its dependent fauna in the impact zones. A biodiversity assessment is one of the requirements in securing the Environmental Compliance Certificate (ECC). This study primarily aimed to assess the biodiversity status in the site. Data were gathered through field surveys employing purposive sampling techniques. The global positioning system (GPS) device was used to get the exact location and elevation of the 350 floral plots and faunal sampling stations. Faunal surveys involved mist-netting and light traps. Ecological parameters analyzed included species diversity, dominance and evenness. Floral results yielded a total of 167 species of plants in 136 genera and 41 families in the project site. Out of 167 plant species, 76 were trees species; 28 shrubs; 24 herbs; 18 grasses; 14 vines; 6 sedges and 1 fig species. Threatened species include Vitex parviflora and Diospyros pilosanthera. Some 51 species of weeds belonging to 42 genera under 16 families were identified. Results showed a total of 26 avifauna species, 4 bats species and 6 anurans. Of the 26 birds, 20 were endemics. The arthropods survey yielded a total of 84 insect species in 14 Orders and 49 families. It was concluded that species diversity of both flora and fauna was moderate to high. There is an urgent need of an enrichment tree planting of indigenous trees in the rest of the island to harbor the fauna that would soon be displaced from the “wipeout zone”.</p>
