This table lists invasive and potentially invasive plant species profiled by the Pacific Island Ecosystems at Risk project (PIER) that occur on Poivre Island. It includes those of environmental concern (including those that are probably of threat only to islands with high elevations) as well as agricultural and ruderal weeds.  Each species is linked by its scientific name to an individual write-up containing relevant information.

The information in this table is based on the supporting data and may not represent the current situation. Note also there may be discrepancies among data presented at geographic resolutions (e.g., island vs. island group vs. country-territory-state levels), depending upon the reliability of the data at each level.

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.
