As would be expected, <strong>the</strong> islands <strong>of</strong> Koror, Malakal, Ngerkebesang and Babeldaob have most <strong>of</strong> <strong>the</strong> weedy species; <strong>the</strong>re are significantly fewer on <strong>the</strong> outer islands. However, a few unique species occur on Peleliu and Angaur. Kayangel, Sonsorol and Ha<strong>to</strong>hobei have <strong>the</strong> fewest invasive plants. Thus, <strong>the</strong>re is <strong>the</strong> opportunity <strong>to</strong> prevent <strong>the</strong> movement and establishment <strong>of</strong> invasive plants on new islands, ei<strong>the</strong>r through interisland quarantine procedures or by surveying for and rapidly responding <strong>to</strong> new infestations. Table C shows critical species that should be subject <strong>to</strong> restrictions on inter-island movement or promptly eradicated if found. Appendices 4 and 5 show species by location while Appendices 6 and 7 show, for each island, all <strong>the</strong> invasive species that are not present <strong>the</strong>re but are present elsewhere in <strong>Palau</strong>. Because <strong>the</strong>y have few invasive plants, exclusion <strong>of</strong> new species is especially important for <strong>the</strong> Southwest Islands. Appendix 6, Tables 8 and 9, and Appendix 7, Tables 8 and 9, show species present elsewhere in <strong>Palau</strong> that are not yet present in <strong>the</strong>se islands. 34
