摘要

In August 2006, over 2 million liters of bunker fuel spilled from a sunken cargo vessel off Panay Gulf, Western Visayas Philippines. Floating oil found its way in the coastline of southern Guimaras including that of a marine protected area, Taklong Island National Marine Reserve (TINMR) (10°24' to 10°26'N, 122°29' to 122°31' E). Most shorelines adjacent to seagrass beds were heavily covered with bunker fuel for weeks before manual clean up were initiated. This study describes temporal changes in structure between 2 adjacent seagrass meadows within TINMR, one with extensively oiled shoreline (CALAPARAN) and the other visually unoiled (KALIROHAN). Seagrass features in TINMR sites were compared to a reference site (LAWI) ~15 km north off the oil spill path. All 3 sites have mixed species dominated by Thalassia hemprichii. Sampling of the seagrass meadows following the oil spill indicate impact in the meadows with oiled shoreline (CALAPARAN). These impacts included: (1) a decrease in seagrass cover and shoot density; (2) generally lower seagrass cover, shoot and blade densities, and above-ground biomass within a year after the oil spill when compared to the other 2 sites; (3) a lower mid-year peak in seagrass cover as part of a bimodal seasonal pattern; and (4) a prolonged decline in shoot and blade densities within a year of the oil spill compared to KALIROHAN.
