The term metabarcoding of environmental DNA as a key indicator for evaluating mangrove ecosystems was introduced. Our previous research results show the important role of mangroves in the context of climate change for reducing greenhouse gas emissions and the diversity of terpenoids for salinity defense. Mangrove forests are threatened with loss due to anthropogenic and non-anthropogenic activities. Mangrove forests are known to provide great benefits to the community as an ecosystem service and globally. Indonesia has the largest mangrove forests in the world, about 22.6% of the global total area. Based on this model, the distribution of mangrove density has the lowest density reaching 400, and the highest density is 2,200 trees per hectare The selected model is Y = 2.48e 2.8667x, which is an exponential equation with a coefficient of determination (R 2) of 61.3%. The study resulted from NDVI selected as the vegetation index used to map the distribution of mangrove density with a Pearson correlation coefficient (R) of 0.738. The distribution model for the density of mangrove stands was chosen based on the coefficient of determination (R 2). Correlation test and regression analysis between the vegetation index value (NDVI, GNDVI, and TVI) to the number of trees per unit area. The density distribution mapping was carried out by compiling a vegetation density estimator model NDVI, GNDVI, and TVI as independent variables. This study aims to determine the relationship between vegetation index and mangrove density in the field and map the mangrove density distribution based on the image vegetation index value. This condition requires prevention and mitigation so that severe damage to mangrove forests does not occur. It can open up opportunities for illegal loggers and trigger damage to these natural ecosystems. FMU has not managed and utilizes mangrove forests optimally. The criteria in accepting papers were based on conference topic suitability, data precision, systematics of English writing, and similarity check results using Turnitin (less than 25%).Įmail : mangrove ecosystem in Forest Managemen Unit - VII (FMU) Sumatera Utara is a natural forest.
