RAS 2015 Non-Native Species Rapid Assessment Surveys in English Marinas (E Anglia & W coast)

This report describes the current distribution of NNS in marinas on the East Anglian and western coasts of England, comparing it to data from previous surveys from 2009/10 and to data from other areas of the UK. It supplements the report from the RAS 2014 project which surveyed the south coast. The data is of relevance to monitoring and pathway management obligations under the Marine Strategy Framework Directive (MSDF); will contribute to the annual compilation of Indicator B6 (Pressure from Invasive Species) of the UK Biodiversity Indicators published by Defra; and to assessing the feasibility of granting exemptions under the Ballast Water Management Convention. The information will be of value to government departments, non-departmental public bodies, environmental charities and other organizations concerned with environmental policy and the management of NNS
