Aquatic Species Invasiveness Screening Kit (AS-ISK) mean outcome scores (± SE) for the species screened for the South Caucasus: A Basic Risk Assessment (BRA) scores B BRA+CCA (Climate Change Assessment) scores. Red bars = very high-risk species; Black bars = high-risk species; Grey bars = medium-risk species; White bars = low-risk (L) species. Solid line = very high-risk (VH) threshold; Hatched line = high-risk (H) threshold; Dotted line = medium-risk (M) threshold (thresholds as per Table 2).
