- In 2007, Invasive Species Ireland carried out a risk assessment of 171 potential invaders. 23 of the highest scoring (potential greatest impact) of these were entered into a Most-Unwanted list and the 50 next highest scoring species were placed on an Amber List for Potential Species.
- The STRIVE project identified a top 13 aquatic Potential high impact species
