Sandwich tern is the key sensitive ornithological receptor for both the Dudgeon site, as well as several other Round 2 wind farm sites currently in planning (Race Bank and Docking Shoal) and under construction (Sheringham Shoal) in the Greater Wash SEA area. It is the potential impact of collision mortality, especially in a cumulative context, upon the population of the North Norfolk Coast SPA that is of key concern for the Joint Nature Conservation Committee (JNCC) and Natural England. An attempt to further understand the implications of the estimated collision mortality at the four Round 2 projects has been made through the use of a bespoke version of Population Viability Analysis (PVA) for the Race Bank and Docking Shoal projects. A decision will be taken in due course as to whether this is appropriate for the Dudgeon project. This note seeks to clarify the results of the CRM for the Dudgeon project issued in Technical Reports (ECON 2009, 2010) supporting the Environmental Statement (Royal Haskoning, 2009). The first of these reports, issued in May 2009, used available data for the 2008 season only. The second report, issued in January 2010, used data for both the 2008 and 2009 seasons (i.e. the two year data set usually required for ornithological surveys).

The model estimates the number of birds potentially colliding with wind turbine generators (WTGs) in two broad steps: • Step 1. Calculation of the number of birds flying through the area of the wind farm whilst it is in operation; and • Step 2. Calculation of the probability that a bird in the wind farm will pass through a rotor and be hit by a rotor blade.
