Abstract

Seagrass beds are crucial for marine ecosystems, providing habitats and food sources for diverse species while naturally protecting coastlines from erosion. These ecosystems play a pivotal role in stabilizing sediments, filtering pollutants, and acting as carbon sinks, which helps mitigate the effects of climate change. Their significance extends to supporting ecotourism and providing essential services to coastal communities, thereby promoting environmental conservation awareness. Saleh Bay, designated as a marine nature reserve, exhibits rich marine biodiversity across its five distinct zones: core, utilization, sustainable fisheries, non-conservation, and other zones. This study aimed a comprehensive understanding of the pivotal role played by seagrass beds in Saleh Bay's integrated ecosystem in West Nusa Tenggara. The density and percentage cover were count from three linear transects and placed perpendicularly to the coastline. Correspondence Analysis (CA) was applied to represents which species most strongly associated with specific zones. Meanwhile, Cluster Analysis was used to grouping specific zones based on the ecological characteristics. A total of eight seagrass species were identified, which dominated by Enhalus acoroides (42.15%) and closely related to Sustainable Fisheries and Utilization zones. Furthermore, the Cluster Analysis indicates that the Utilization and Sustainable Fisheries zones exhibit the highest degree of similarity (90%) based on their density characteristics. This research underscores the broader understanding of seagrass ecosystems. The high similarity between the Utilization and Sustainable Fisheries zones suggests that these areas play complementary roles in supporting the health of seagrass ecosystems. Management plans should integrate these findings to optimize resource use while ensuring ecological sustainability.

Abstract

Cempi Bay is an important water area with a rich and diverse ecosystem. One crucial component of marine ecosystem that plays a major role in maintaining the balance of the marine environment is seagrass. The objective of this research is to provide critical insights into the dynamics of seagrass populations in Cempi Bay and offer an overview of the broader coastal ecosystem's condition. The research, conducted in June-July 2021 at 5 research stations, employed the transect method. At each data collection point, three transect lines were created perpendicular to the coastline. The distance between transect lines was 100 m, and each transect consisted of 10 quadrants measuring 1x1 m with a 5 m distance for each quadrant. Four seagrass species were identified: Thalassia hemprichii, Cymodocea rotundata, Halodule pinifolia, and Cymodocea serrulata. These species were found on sand substrates, with the highest total density and percentage cover observed at Station 5 (1135.22 ind/m2 and 40.74%). The results highlight the necessity for routine monitoring, mapping, and further research to comprehend seagrass population dynamics and support effective conservation policies. Implementation of recovery strategies, water quality management, and continued research support is imperative to ensure the sustainability of seagrass ecosystems and marine resources in Cempi Bay.
