The study was conducted to determine the present status of seagrass resources of Laguindingan, Misamis Oriental, and Kauswagan, Lanao del Norte, and compared this through time with secondary data. It employed the transect-quadrat methods. Perpendicular to the shoreline, three (3) 100-m transect lines at the 200-m intervals between each transect were laid. Seven seagrass species were recorded comprising 38.6% of the total number (19) of seagrass species found in the Philippines. The seagrass community in all sites surveyed showed that it is highly dominated by Thalassia hemprichii species. However, there were no significant differences in species richness and diversity based on a single-factor ANOVA statistical analysis (p>0.5). The abundance of T. hemprichii could probably be due to the prominent characteristic of this species where it could grow well in different types of habitats with various environmental conditions. The condition of seagrass beds in both areas was fair and the low Shannon-Wiener Diversity Index of seagrass in Kauswagan, Lanao del Norte (H’=0.76±0.22) and in Laguindingan, Misamis Oriental respectively (H’=0.40±0.35) indicate low stability in the community, which means that the condition of the seagrass ecosystem could be under threat, both from natural and anthropogenic activities. Over time, a fluctuating trend in species composition and a notable decline in seagrass species diversity and abundance have been observed in both areas. This present status calls for an immediate response from the decision-makers concerned about the sustainable management and conservation of seagrass resources.
