Mangrove has physical and ecological functions that are very influential on coastal ecosystems. Mandeh area is currently one of the ecotourism areas that has a fairly extensive Mangrove forest. However mangrove condition is being threatened due to various reasons. This study to determine the zoning pattern of the Mandeh mangrove forest using two different methods: (a) field survey using belt transect method with determination of plot points determined by purpose sampling (b) method with unmanned aircraft using 3- dimensional visual analysis by utilizing orthophoto data recorded by unmanned aerial vehicles (UAV). Data were presented in tabulation form, then analyzed qualitatively and quantitatively. The results revealed that the zonation pattern of mangrove forests using the field survey method can provide results in the form of a more detailed zonation pattern, the number of individual trees, tree diameters, and the types of species that dominate. Observation of the zonation pattern of mangrove forests using UAV method providing accurate results in the form of general profiles of mangroves, and individual tree heights. The implication of this research will be useful as a consideration in making policies on mangrove conservation in Nagari Mandeh.
