Proposed UK Targets for achieving GES and Cost-Benefit Analysis for the MSFD: Final Report Appendix February 2012 Proposed UK Targets for achieving GES and Cost-Benefit Analysis for the MSFD: Final Report Appendix This report describes expert advice to support the development of proposals for UK targets and indicators of Good Environmental Status, including an initial cost benefit analysis for the implementation of the MSFD. A large number of contributors from the marine science community have helped with the development of these proposals, coordinated by expert panels and the Evidence Groups of the UK Marine Monitoring and Assessment Strategy. Significant input to this Cefas project report (ME5405) has been provided by the HBDSEG Drafting Team and eftec.

Non-indigenous species introduced by human activities are at levels that do not adversely alter the ecosystem There are some non-indigenous species (NIS) currently present in the marine environment and there are many examples from throughout the world of unsuccessful attempts to remove these. It therefore has to be accepted that for the most part the species already present cannot be eradicated. GES for non-indigenous species (NIS) in UK waters can therefore best be achieved by preventing new introductions. Management-based targets should be set such that the risk from pathways and vectors which facilitate the introduction and spread of NIS have been significantly reduced. The impact from and spread of invasive alien species (IAS, a minority subset of NIS, which are demonstrated to have an adverse effect on biological diversity, ecosystem functioning, socio-economic values and/or human health) will be reduced as a consequence of this approach. This approach also allows for the fact that it is not always possible to predict which NIS will become AIS. Also, management measures will be more effective if they are applied at least at regional seas (if not international) level and so ideally they should be coordinated between Member States. Although understanding of the main pathways and vectors of introduction are improving, a better assessment of current status is needed to provide a basis for future measures. There is some uncertainty that targets based on implementing management measures to reduce impacts will be acceptable to the Commission. Criterion 2.1 - Abundance and state characterisation of non-indigenous species, in particular invasive species Indicator 2.1.1 - Trends in abundance, temporal occurrence and spatial distribution in the wild of non-indigenous species, particularly invasive non indigenous species, notably in risk areas, in relation to the main vectors and pathways of spreading of such species Type of targets It will not be possible to develop robust targets on the basis of numbers and distribution of NIS in UK waters, due to the lack of sufficiently detailed knowledge on current status that arises from the difficulty of obtaining up to date information. Such targets are also constrained by the difficulty of removing these species once they have become established in any location. There will have to be an acceptance that non-indigenous species, including invasive species, will remain in the marine environment and that new introductions will never be entirely prevented. Page 4 of 337 Proposed UK Targets for achieving GES and Cost-Benefit Analysis for the MSFD: Final Report (appendix) Trend based targets, based on long term monitoring at high risk sites for introduction, for example selected marinas or ports, and in marine protected sites identified as vulnerable to introduction and spread of particular IAS, could be developed.
