Pacific Island Ecosystems at Risk (PIER)

Plant Threats to Pacific Ecosystems

Following are lists of plant species that are invasive (or potentially invasive) on Pacific islands:

• Scientific names lists - species of concern to the Pacific islands with links to individual summaries (includes high elevation species–see below)
• Scientific names by family - complete list of species as above list but sorted by family rather than by species
• Common names lists - alphabetically and by language
• Listed by location (region; country, territory or state; island group, island)
• Listed by growth habit (herb, shrub, tree, etc.)
• High elevation species - species that are primarily a threat to tropical ecosystems over 1000 m elevation or temperate islands.

Hint - To search for a species, load one of the above lists and use your browser's "find" function to locate a specific name.

You can also access the following lists:

• Risk assessments for invasive and potentially invasive species
• Prospective species - species that are under consideration to be added to PIER (your comments would be appreciated)

Information at this site is periodically updated. As additional plant threats are confirmed, they are added. You can help! If you know of an invasive species that should be added or can contribute information, photos, or line drawings, please let us know.
