Mangroves, a vital coastal ecosystem on earth, are threatened due to human destructive activities. Current, accurate, and reliable information on the extent of mangroves and its distribution is limited. Partial monitoring requires more comprehensive approach, especially in calculating the areal extent in a certain period of times. Therefore, monitoring by analyzing Landsat imagery could provide accurate and reliable data in determining the areal extent and spatial distribution of mangroves. We used publicly available Landsat data during the period of 1997-2018. The data, subsequently, was analyzed by supervised maximum likelihood technique and followed by a direct field validation with the total sample of 45 points (33 mangroves and 12 non-mangroves). The results of Landsat imagery analysis of 5 TM (1997) and 8 OLI (2018) reveal that approximately 82.22% and 86.67 of overall accuracy with the areal extent of mangroves in 1997 was about 44.75 Ha, increasing to about 88.83 Ha in 2018. This represents a significant increase of mangroves extent during that period as it is a result of reforestation. Rhizophora stylosa dominates the mangroves closed by Cemara beach, while Sonneratia caseolaris is abundant in the estuary. This information could be used as a basis for policy makers to create a sound regulation to mitigate the mangroves destruction as well as forcing the conservation efforts in Lembar Bay.

| Meta Desc | The Indonesian Journal of Aquaculture and Fisheries (IJAF) is an open access scientific journal. IJAF accepts applied/scientific research manuscripts (including review articles and brief communication) related to all aspects of aquaculture, capture fisheries, fisheries product processing, and fisheries socio-economics (technology, social, economic, ethical / norm, management, policy , conservation, and models). IJAF editors also use Similarity Check to avoid alleged plagiarism and other fraud or scientific errors in the text. IJAF will be published twice a year in April and November by the Faculty of Fisheries, University of 45 Mataram, Indonesia. All articles received will be published on the payment of article processing fees (Article Processing Cost / APC) to support various financing, and will be freely available to the public. |
