D2C1: Newly introduced non-native species The number of non-native species newly introduced through human activity into the wild per assessment period (six years), measured from the reference year and reported in the initial assessment, is minimised and where possible reduced to zero.

D2C2: Established non-native species, in particular non-native invasive species that are included in the list of relevant species for use in the assessment of the criterion, are at levels of abundance and distribution that do not adversely affect the ecosystem

D2C3: Species groups and general habitat types exposed to risks from non-native species for descriptors 1 and 6 are in a proportion per species group and extent for each major habitat type assessed that does not adversely alter native species and habitat composition.
