Abstract:
The dwindling stature of the ecosystem of today has drawn
attention to its neglected aspects. It is only now that
people are learning the importance of the seagrass
community. The coexistence of Organisms in the estuarine
regions has laid a bigger importance on seagrasses, thus,
prompting this research. Using three transect lines of 100
meters in length each; a taxonomic survey of the seagrass
community in the Northern Coast of Semirara Island,
Antique was done. The results of the study show that after
having computed for the Shannon's Diversity Index, the
index was highest for seagrass (0.6393) while lowest for
alga (0.3003). In Site C, the index was lowest for seagrass
(0.2788), while highest for alga (0.4369). Likewise, it can
be noted that the following species of seagrasses can be
found in the sites: Enhalus acoroides, Cymodocea
rotunda/a, Cymodocea sp., Halodule pinifolia, Halodule
sp., and Halophila ovalis. Meanwhile, the following
species of algae were found: Halimeda macroloba,
Halimeda sp., Valonia sp., Galaxaura sp., and Dictyota
sp. The seagrass community can be characterized by the
dominant species, which is the Cymodecea rotundata.
