CONCLUSION AND RECOMMENDATION

Background of the Study

Philippines has one of the largest coastal areas

Underwater ocean grass—Seagrasses

Benefits of seagrassessBreeding area for fishesCan be harvestedReduce current energyFilter suspended sediments

Avoid destruction of seagrasses

Objectives of the Study

Select representative sampling sites to be surveyed;

Baliangao, Misamis Occidental

1. Protected area – Danao Bay, Baliangao

2. Disturbed areas – Jingle Bells Beach, La Esperanza Beach, and Arjan’s Place, Baliangao

Obtain the physicochemical properties of the sampling sites;

Survey the seagrass community via transect and quadrat; and

Compare the biodiversity indices between the two areas – Protected area (Baliangao

Protected Landscape and Seascape) &

Unprotected area (Arjan’s Place, La Esperanza Beach,

Jingle Bells Beach)

Significance of the Study

Distinguish the impact of human activities

Determine the health condition of the body of water

Provide information

Scope and Limitations of the Study

Classify seagrass to genus level

Waste contributors causing unhealthy condition is beyond the scope and limitation

Limited only to the two selected sampling areas – Protected and Unprotected Areas
