Mangroves are one of the most important natural resources in coastal areas. Availability of various types of food that are on ecosystems is already making its presence as a local nursery, where searching for eating and also serve as a regional tourist ecosystem of mangrove.

Research is carried out in the month October to November 2019 in the village of Juanga Regency island of Morotai.

The research results of the study found 5 types of mangroves namely Rhizophora mucronata, Ceriops decandra, Rhizophora apiculata, Xylocarpus granatum and Sonneratia alba. The distribution of zoning patterns in the front zones of station I and the middle zone is dominated by Rhizophora mucronata and Rhizophora apiculata types, the rear zone is dominated by Ceriops decandra. Station II front zone is dominated by Sonneratia alba, middle zone (Rhizophora mucronata), rear zone (Ceriops decandra). At station III the front zone (Rhizophora apiculata), the middle zone and the rear zone (Ceriops decandra) while at station IV the front zone, the middle zone and the rear zone are dominated by the Ceriops decandra type.
