Abstract


This study was carried out in mangrove forest of Bahoi, Likupang district, North Minahasa regency. It was aimed at knowing the ecological condition of the mangrove forest. Study stations were selected by determining representatives from each zonation and site condition. Results showed that mangrove species in Bahoi was dominated by Rhizophora mucronata, R. apiculata, Bruguiera gymnorrhiza, B. cylindrical, and Sonneratia alba, with the highest density in station 1 shown by Rhizophora apiculata, 0.65 ind/m2, then station 2 and 3 by  R. Mucronata, 0.93 and 0,63 ind/m2, respectively.  The highest total density was recorded in station 2, 1.85 ind/40 m2, then station 1, 1.78 ind/40 m2, and station 3, 1.35 ind/40 m2, respectively. As conclusion, the ecological condition of mangrove ecosystem in Bahoi was categorized as good, and aware to be beneficial for the local community in ecological function as abrasion prevention and living environment of the aquatic biota and in economic function from ecotourism aspect, so that it was right to be managed in the form of ecotourism management.
