Training for a community-based coral reef monitoring program was carried out in the village of Blongko, North Sulawesi. A manta-tow based method was selected because it is a relatively simple technique to enable the community to determine whether coral reef conditions are becoming worse, better or staying the same. Data collected by the community was compared with data collected by independent professional survey. The correlation coefficient, r, between the two data sets is 0.825. A matched pair t-Test was performed on the two data sets and the difference between the two was determined to be not significant (p0.05). These preliminary results compare favorably with the other volunteer-professional data comparisons from the United States (USEPA, 1990): the value of the correlation coefficient is likely to increase with an increased sample size
