2012, RPS, Lincs Offshore Wind Farm, Second Interim Boat-based Bird Survey (August - October 2012) series https://portal.medin.org.uk/portal/start.php?tpc=015_0cba8800-c976-4a99-b3f9-6523ddb0b2cd Ornithological boat-based surveys have been conducted to inform of any changes to the abundance and distribution of species between the pre-construction and during-construction periods of the Lincs/LID6 Wind Farm. This interim report presents the results of the surveys during the period August to October 2012, which formed part of the Year 2 Construction period. In general, estimated numbers in 2012 were largely similar to those found in previous years within this period, and where there were some differences (e.g. Sandwich tern, razorbill), it could not be determined with any confidence that this was due to the presence of Lincs/LID6 construction activities or part of a wider natural variation in numbers. There was however no clear evidence that any key species have been adversely affected by such construction activities. This information will form part of a more comprehensive Year 2 Construction period annual report, which will statistically test for any changes in the abundance and distribution of species in relation to the Lincs/LID6 construction activities. 2013
