Abstract: Indonesia's marine ecosystems form a fundamental part of the world's natural heritage, representing a global maxima of marine bio ersity and supporting the world's second largest production of seafood. Seagrasses are a key part of that support. In the absence of empirical data we present evidence from expert opinions as to the state of Indonesia's seagrass ecosystems, their support for ecosystem services, with a focus on fisheries, and the damaging activities that threaten their existence. We further draw on expert opinion to elicit potential solutions to prevent further loss. Seagrasses and the ecosystem services they support across the Indonesian archipelago are in a critical state of decline. Declining seagrass health is the result of shifting environmental conditions due largely to coastal development, land reclamation, and deforestation, as well as seaweed farming, overfishing and garbage dumping. In particular, we also describe the declining state of the fisheries resources that seagrass meadows support. The perilous state of Indonesia's seagrasses will compromise their resilience to climate change and result in a loss of their high ecosystem service value. Community supported management initiatives provide one mechanism for seagrass protection. Exemplars highlight the need for increased local level autonomy for the management of marine resources, opening up opportunities for incentive type conservation schemes.
Changes in the Ambon Bay Seagrass for the Past Five Years (2011 – 2016)
Publisher: IOP Publishing

DOI: 10.1088/1755-1315/618/1/012025
Abstract: Ambon Bay is located on Ambon Island, which most of the area is within the Ambon City, the capital of Maluku Province. The coastal ecosystem such as coral reefs, mangroves, and seagrass beds still exist on this bay. However, as a coastal ecosystem in a crowded city, the potential of degradation for these ecosystems is immense. Over the past five years, many changes have taken place in this bay. In the land section, the construction of housing and large buildings such as shopping centers has occurred. Besides, on the coast, there has been a construction of new docks, and several locations have been reclaimed. Therefore, in 2016 there was a re-observation of the seagrass condition at all transect locations of 2011, to see the changes that have occurred in the seagrass bed in Ambon Bay over the past five years. The results will be compared to the satellite imagery of each location. Overall, the condition of seagrass beds in Ambon Bay in 2016 has decreased from the initial observation in 2011. Of the seven research locations, only one location (Halong) has an increase in its conditions, with seagrass canopy cover rise by almost twofold from previous data (24.29% rise to 50.00%). Four locations experienced a decline in condition, from a slight decrease in Waiheru and Lateri (25.00% down to 20.91% and 47.14% down to 39.33% respectively) to a sharp decrease in Tanjung Tiram and Passo (65.67% down to 39.33% and 48.33% down to 16.25% respectively). The remaining two locations (Tantui and Hative) were in worse condition because they were damaged by the reclamation project. From 2011 to 2016 satellite image comparison, almost all locations show changes in their land use, with more buildings built near and on the coastal area, except in Halong. This finding indicates that seagrass condition negatively affected by coastal development.

Status of seagrass beds in Ternate and surrounding areas

DOI: 10.1088/1755-1315/339/1/012011
Abstract: Seagrass bed is one of important ecosystems usually located adjacent to coral reefs and serves several important ecological roles such as feeding and nursery ground for several marine biotas. Physically, seagrass bed protects the reef from inland sedimentation. The status of seagrass beds, therefore, becomes an important thing in protecting the coral reef ecosystem. The study was conducted on July 2018 with the objective to analyze the current status of seagrass bed at Coral Reef Rehabilitation and Management Program (COREMAP) site in Ternate Island. Ten stations were chosen for this study and linear transect method was used to analyze species composition and canopy coverage. The result showed that there are 8 species found in this area with 5-7 species commonly found at each station. Among 8 species found, Thalassia hemprichii being the most common species inhabiting all of the sites. Average canopy coverage in seven stations was below 59.9% which considered as less healthy, whilst at other three locations was below 29.9% which considered as poor status. Overall, the status of seagrass beds in this area is less healthy with moderate canopy cover. This status has remained the same since 2015 to the present time.
