Mangrove Ecosystem Identification and Density in Geopark Ciletuh, Sukabumi, West Java, Indonesia

Mangroves are one of the most important parts of the marine coastal ecosystem Mangroves are ecologically important components of the coastal ecosystems that are under severe threat globally from a range of causes, they provide potential contributions in ecological services, provides habitat for many terrestrial and marine species, various food resources, shelter and site for fertilization for variety of aquatic fauna resulting into rich biodiversity. One of the locations of mangrove forests in Indonesia is Geopark Ciletuh, Sukabumi. The area of mangrove forest at this location is about five hectares. The decline in the quality and quantity of mangrove forests can affect the economic life of coastal communities, such as decreasing fish catches and decreasing fishermen's income. The research in this study aims to determine the type and condition of the density of flora and fauna of the Ciletuh mangrove forest in order to determine the development and changes of the observed mangrove forest from time to time. Data were obtained using survey techniques and analysis of mangrove vegetation with the quadratic transect method. The types of flora found were 12 families of 18 mangrove species with the highest density value found in the Avicenniaceae family of 60 individuals/ha or 37.37% of the total density and a diversity value of 2.05 which was classified as moderate, while the fauna found were 12 species with a species diversity value. fauna of 0.62 which is relatively low.
