An offshore wind farm could in theory have an effect on a range of species other than just seabirds, as a result of the nature of the different potential impacts. The latter are typically thought to include: · Mortality as a result of collision with wind turbine generator (WTG) blades, towers and ancillary structures during operation; · Disturbance and displacement from preferred areas used for feeding, roosting, resting, moulting or passage, during the construction, operation and decommissioning phases; and · Indirect effects through changes in habitat or prey supply during construction and operation.

The latter dataset was fully analysed in the Dudgeon Environmental Statement published by Dudgeon Offshore Wind Limited (Royal Haskoning, 2009), and as no further aerial surveys have been undertaken since that publication, no further analysis of aerial data was undertaken for the present document. Information on seasonal patterns of abundance and distribution of key species, derived from aerial surveys, is included in the following analysis, but reference should be made to the previous document for a complete detailed account of aerial survey results. In addition to these data sources, a series of sources of literature were thoroughly assessed to set the context of the birds recorded at Dudgeon and the likely impact of the site. These are outlined below (see Section 2.1.4).
