| Summary: | Seagrass, as a part of the coastal ecosystem, are very unique due to their
distinct adaptation to the submarine environment. Despite their limited diversity,
seagrass support vast variety of life and play important socio-ecological role to
coastal area. Objectives of this study are: (1) to know the condition and status of
seagrass ecosystem, (2) to study human exploitation activities and threats on
seagrass ecosystem, and (3) to analize management of seagrass ecosystem. Study
was conducted on March 2014 at four islands in settlement zone of Kepulauan
Seribu Marine National Park (Panggang, Pramuka, Kelapa, and Harapan island).
Social data was obtained from semi-structured interview from snowball sampling
design, meanwhile seagrass data was obtained from quadratic transect method.
Study result shows that seagrass species in Kepulauan Seribu Marine National
Park consist of 2-7 species with 58,9 shoot/m2 density and mainly in damaged
status (percent cover <30%). Interview data shows that seagrass ecosystem have
being part of society�s life from early time (ngoyok, tegur net, and marineculture).
Nevertheless, there are lack of people�s knowledge about this ecosystem. The
main threat to this ecosystem sustainability are sand exploitation, and also
dredging and burial as part of area development in reef flat. Seagrass ecosystem
management based on balanced use and conservation is an appropriate concept
considering the ecosystem and society�s condition now.
