Abstract

This study was carried out in Sauk village,  Lolak district, Bolaang Mongondow regency on June 10th – August 11th, 2016, around mangrove ecosystem at the geographic position of 0⁰ 50’ 10^’’ N and 123⁰ 56’ 40’’E. It was aimed to a) assess the ecological condition of the mangrove ecosystem of Sauk village based upon the community structure and (b) estimate the economic value of the mangrove ecosystem from direct and indirect benefit. Results found that the ecological value of the mangrove ecosystem was categorized as “rare” (<1000 trees/Ha), with low diversity index (< 2), and Sonneratia alba had very important role with the highest IVI. Total economic value was IDR. 1,116,830,000 per year based upon the benefit value.
