Abstract

Increasing recognition of the threat which invasive non-native species present to ecological and economic assets has led to a recent surge in international, regional and national policies. Within the European Union, a draft EU Regulation on the prevention and management of invasive alien species has been developed. The draft Regulation, published in 2013, recommends the creation of a list of invasive alien species of Union concern, wherein any Member State identifying newly establishing populations of these species must implement rapid eradication measures. The first recording of the invasive non-native ascidian Didemnum vexillum in Britain in 2008 in Wales, and subsequent eradication efforts, presents a timely opportunity to evaluate the United Kingdom׳s existing capability and capacity to undertake a rapid eradication in the marine environment in light of the draft EU Regulation, as well as highlighting some of the cross-border challenges facing the EU. Although the UK is often cited within Europe as having made significant progress in the field of invasion management, the lessons learned from the eradication process in Wales highlight that the UK is inadequately prepared to undertake rapid eradication measures in the marine environment and that the lack of a coordinated approach between nations has significant potential to devalue localised eradication efforts. A number of measures are discussed to enhance future capability both in the UK and the wider European Union including enhanced alerting mechanisms, science-based monitoring programmes to enable early detection, increased commitment of resources and the need for cross-border collaboration.
