Three stations were obtained, namely in the villages of Sialang Buah, Sentang and Bogak Besar. The results was found that the mangrove forest in Teluk Mengkudu District was categorized as severely damaged (rare) with a density of 741 ind/ha. The mangrove restoration strategy is the first step of initial research to determine the ecological conditions of the coast and mangrove diversity, the second is outreach to the community and creating a team, the third is making beds, the fourth is the nursery with a total number of 145,500 seedlings and 29,100 embroidery seeds to be planted in 4 villages, the fifth step construction of a hybrid engineering building with a total planning length of 5,300 m. the sixth step is planting mangroves, the seventh is embroidery and the last is maintenance.
