This report describes the current distribution of NNS in marinas on the coast of S England,
comparing it to data from previous surveys from 2009/10. The data is of relevance to
monitoring and pathway management obligations under the Marine Strategy Framework
Directive (MSDF) and to assessing the feasibility of granting exemptions under the Ballast
Water Management Convention. The information will be of value to government
