Item Phytosociological study of Romulo Island and Little Island in Taklong Island National Marine Reserve , Nueva Valencia, GuimarasAnas, Enya Lou M. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2017-09)Taklong Island Marine National Reserve encompasses not only marine and mangrove ecosystems but also small islands that are made up of beach forest species. In this study, small islands Romulo and Little Island were surveyed to assess and compare the species composition, community structure, and diversity of their vegetations in terms of their stand height, stand basal area, basal cover, plant density, and importance value along with ecological indices like species richness and Shannon- Wiener Index of Diversity. The phytosociological study was achieved through the establishment of random plots and measurement of diameter at breast height (DBH) of the identified plants found in both islands. Results show that 11 species belonging to 7 families were identified in Romulo Island, with Syzigium confertum having the highest importance value. Little Island, on the other hand, have 26 identified species belonging to 18 families, with Cerbera manghas having the highest importance value in the island. Moreover, results also show that Little Island is more diverse and more even than Romulo Island based on the diversity indices. These results are attributed to environmental factors like climate, island size, wave action, and wind exposure unique to both islands. Moreover, the dispersal mechanisms of the plants and anthropogenic activities also contribute to the survival of plants on the islands.
