Annex F NatureScot (2020) non-breeding season Matrices for Kittiwake, Razorbill and Gannet

As described in section 3.3, use of NatureScot non-breeding season definitions presents issues for non-breeding season apportioning (Technical Appendix 11.5: Ornithology Apportioning Technical Report) for those species where the autumn and spring passage and winter periods are defined within the non-breeding season (gannet, kittiwake and razorbill). This is only true for assessment of the Berwick Bank Development Array plus a 2 km buffer; the mortality figures of which are used within the apportioning analysis.

The non-breeding season displacement for kittiwake, razorbill and gannet, as defined by NatureScot (2020), are presented here for reference only. These outputs are not used within the Technical Appendix 11.5: Ornithology Apportioning Technical Report.

Table F.1: Potential kittiwake mortality following displacement from the Berwick Bank Development array plus 2 km buffer in the non-breeding season. Estimates considered, in light of empirical evidence, to represent the most realistic scenarios are colour coded, with dark teal representing rates advised by the Scoping Opinion and light teal representing uncertainty around these figures. A quantitative assessment is not being made for kittiwake in the non-breeding season under the Developer Approach (see Annex G for justification).
