Floristically, forty (40) species of plants which represent thirty (30) families and Dipterocarpaceae (5 species) are the family which has the most species. The vegetation analysis in Mandul Island is done by using plot method. In this analysis, the growth of plants from variety of growth level is observed like seedling, sapling, pole and tree. The dominant plant species which refers to Summed Dominance Ratio (SDR) and Important Value Index (INP) are seen in this vegetation analysis. The vegetation analysis result shows the Bauhinia purpurea (40 individuals) is the dominant plant with SDR value 9.84 and INP valui 19.69. The sapling level consists of 21 species, the dominant species is Macaranga hypoleuca (11 individuals) which has SDR value 10.95 and INP value 32.8. The pole level has 17 species with Macaranga Triloba (8 individuals) as the dominant plant, this species has SDR value 11.45 and INP value 34.35. In other hand, it's found 10 species from 6 families with Dipterocarpus borneensis (5 individuals) as the dominant plant which SDR value is 18.25 and INP value is 54.76. The highest community similarity index is 84.21% which is found in sapling and pole growth level. In health point of view, forest vegetation indirectly has a role in preventing outbreaks of diseases caused by the increase in global temperatures due to global warming; one example is a diarrheal disease caused by bacteria, entamoebae, and protozoa which all of them like high temperatures.
