Species listed as invasive come from the Invasive Species in Ireland prioritization risk assessment last undertaken in 2013.  From this, 48 non-native species were ranked as at risk of having a High Impact and 78 species at risk of having a Medium Impact.

Prioritisation risk assessment is key to understanding the relative risk associated with a larger array of species. This assessment is required primarily for prioritisation and informing decisions that do not have an impact on trade. The prioritisation risk assessment was carried out for 377 non-native species recorded in Ireland and 342 non-native species not known to present in Ireland (potential invaders). These species were assessed, scored and ranked into impact categories of high, medium and low.

Of the 342 potential invaders that were risk assessed, 51 species ranked as possibly having a risk of High Impact. It is important that these species are not introduced into the wild in Ireland and if they do, that they are spotted and removed as soon as possible. These are known as our Watch List species.

In 2014, 41 non-native species underwent a detailed risk assessment. This is a more comprehensive risk assessment process than the prioritization risk assessment.
