2010, Amec, Scottish territorial Waters Offshore Wind Farms West Coast, Marine Mammals Cumulative Study series https://portal.medin.org.uk/portal/start.php?tpc=015_9aa5e24a-bede-10c7-9ae2-fe2e81a796e4 COWRIE has recently issued guidance on cumulative impact assessment for ornithology, which has been adapted here for use with marine mammal species (including basking shark). This proposes the use, at the scoping stage, of ‘key features’ tables to identify a list of species which may be at most risk of cumulative impacts (Prior, A. in King et al 2009). The tables are designed to provide a robust and auditable basis for initial discussions with Scottish Natural Heritage (SNH), Joint Nature Conservation Committee (JNCC) and other stakeholders about the potential for significant effects on priority species. It is important to note that the use of these tables is a novel development and the process will require refinement. The outputs of this study will be used in the assessment phase for individual projects to provide an agreed, standardised starting point for the cumulative impact assessment. This assessment also includes Basking sharks due to their similar behaviour to marine mammals and wide-ranging nature. 20111001
