Abstract:
The surrounding waters of Tulehu Village are coastal areas with ecosystems such as seagrass, adjacent to marine natural resources (mangroves, macroalgae, fish, mollusks, etc.). Seagrass in the coastal waters of Tulehu has spread widely, but information about seagrass communities in these waters is limited. This research was conducted to describe the species composition, density, frequency of occurrence, percentage of coverage, importance value, biomass, and distribution of pattern of seagrass in the area. The method used is the quadratic linear transect method. The results of the study showed that there are four seagrass species Cymodocea rotundata, Halodule pinifolia, Halophila ovalis, and Thalassia hemprichii. The highest values of density, frequency of occurrence, percentage of coverage, importance value, and biomass were found for H. pinifolia. The lowest values for density, percentage of coverage, and biomass were found for H. ovalis, while T. hemprichii had the lowest values for frequency of occurrence and importance. Spatial distribution based on density, percentage of coverage and biomass
have the values of >10 stands m-2, >40% and >200 g m-2, respectively.
