This table lists species that are considered to be primarily a threat to tropical ecosystems over 1,000 m elevation. While they are profiled on PIER, most Pacific islands do not exceed this elevation and thus these species may only be a problem or potential problem in a limited number of locations. Each species is linked by its scientific name to an individual write-up containing relevant information.
Species are listed in alphabetic order. You can browse this list or use the "find" function on your web browser to search by scientific name.
