The diversity category is classified as low and moderate, the diversity of coral species with moderate categories is found at station 4 with the number of species found as many as 40 species and the lowest coral species diversity at station 2 with the number of coral species is 13 species. The percentage of coral reef cover on Tidore Island ranged from 18.25 - 58.76% with poor to good categories.
