Figure 1: Distribution of Weed Risk Assessment (WRA) scores of 38 Eucalyptus taxa evaluated for the USA. Scores 1 suggest that the taxon is a low risk for invasion; scores of 1–6 indicate that the taxon requires further evaluation unless a secondary screen [23] allowed resolution to a risk outcome; scores 6 suggest that the taxon is a high risk for invasion [8]. See Table 1 for identification of the taxon associated with each score. Numbers within bars correspond to numbers in the first column of Table 1.
