Pacific Island Ecosystems at Risk (PIER)

About the Pacific Island Ecosystems at Risk project (PIER)

The ever accelerating rate of biotic invasion is a major element of human-induced global change. Alien plant species, in particular, pose a well-confirmed and increasing danger to ecosystem integrity, especially on islands. The purpose of the Pacific Island Ecosystems at Risk project (PIER) is to compile and disseminate reference information on exotic plant species of known or potential threat to Pacific island ecosystems. Emphasized are plant species that are threats to natural or semi-natural ecosystems of all types, but information is also included on species that are agricultural weeds or invaders of other disturbed sites.

PIER was originally requested by the Pacific Island Committee, Council of Western State Foresters, National Association of State Foresters. It is funded by USDA Forest Service International Program funds. Project direction is provided by the U.S. Forest Service’s Institute of Pacific Islands Forestry with the assistance of a number of cooperators.

In addition to this web site, information is being contributed to the Invasive Species Specialist Group database.

Web site hosting and other support is provided by the U.S. Geological Survey and the Hawaiian Ecosystems at Risk Project (HEAR).

Project leader and editor is Jim Space. Contact.

Botanical identifications by Marge Falanruw (Institute of Pacific Islands Forestry), David Lorence and Tim Flynn (National Tropical Botanical Garden), Clyde Imada (Bishop Museum) and Barbara Waterhouse (Australian Quarantine Inspection Service).
