Hawaiian Pacific Weed Risk Assessment (HPWRA)

This is a risk assessment tool targeting parties interested in importing, selling or growing plants. Experts screen a plant species to assess its invasiveness. Users can access a list of plant assessments, or submit the name of a plant species for screening. HPWRA botanists look up published and on-line information to answer 49 questions about a plant’s biology, ecology & invasive tendencies elsewhere. The answers result in a score that predicts whether a plant is likely to be invasive in Hawai‘I or other tropical Pacific islands sharing a similar climate.
