Welcome!  Here you will find listings and descriptions of plant species that threaten ecosytems of the Pacific islands.  Also listed are many other invasive and potentially invasive plant species present in and around the Pacific region.

Status of PIER:  PIER is no longer being updated.  The last updates were made 15 May 2013 and were posted 1 June 2013.  However, PIER will remain online into the foreseeable future as a source of information on known and potentially invasive plant species in the Pacific region. 

The Forest Service would like to find an individual or organization that is interested in maintaining and possibly updating the PIER web site.  If you might be interested, contact me: Jim Space, PIER




Information on some species may be incomplete or missing.   Contributions of information, photos, drawings, etc. are solicited and will be properly credited or cited.  Also, please look at the list of possible additional species and let us know if you think they should be added as threats to Pacific islands.
