摘要：Potential vegetation in a small island ecologically plays an important role towards life sustainability of wild animals in the island. To find out the compositions, structures, and benefits of vegetation in forest ecosystem of small islands, a vegetation analysis was needed. The result of analysis was beneficial, helping to find out the condition of forest community balance, as well as to explain the interactions inside and between species. Vegetation observation was needed in Utilization and Protection block in Ontoloe Island, from littoral to terrestrial until the center of the island. A combination of Judgemental and Systematic Random Sampling was applied to determine the research sites in 2 blocks. In the Utilization block, 3 sites were identified, while in the Protection block, other 4 sites were determined. The distance of each site was 100 meters. In every site, there were 3 replicas at a distance of 50 meters. The vegetation data obtained was analyzed the Importance Value Index (IVI). The result of the research based of IVI obtained showed that Leucaena leucocephala dominated the tree, pole, and stake levels, Imperata cylindrica dominated in seddling level, whereas Rhizphora mucronata dominated the littoral area. The domination of invasive species of Leucaena leucocephala and Imperata cylindrica has threatened and reduced the vegetation diversity in Ontoloe Island. Biological controlling both 2 species could be used by introducing ruminant animals such as timor deer (Cervus timorensis), which in turn would conserve the ancient Komodo dragon (Varanus komodoensis Ouwens, 1912) in Ontoloe Island, by providing enough feeds of Timor deer for komodo.
