2010-2013, RPS, Inner Dowsing, Lynn and Lincs Offshore Wind Farms, Radar Monitoring of Pink-footed Geese Migration series https://portal.medin.org.uk/portal/start.php?tpc=015_71c1557f-70a5-43fd-92a1-1dbd001a603e RPS, in collaboration with the Food and Environment Research Agency (FERA), were commissioned by Centrica to investigate this migration using radar prior to offshore construction commencing in spring 2011. Lincs Wind Farm Ltd (LWFL) will commence installation of the Lincs/LID6 offshore wind farm, comprising 75 wind turbines offshore from Skegness during 2011. The Lincs/LID6 array will lie immediately to the east of the existing turbine arrays of Lynn and Inner Dowsing (LID) (Figure 1). The proposed turbines are Siemens SWT-3.6-120’s which have a 120 metre rotor diameter and a hub height of 85.25 metres above mean sea level. And a subset of the UK’s wintering pink-footed geese Anser brachyrhynchus pass through the area in the vicinity of the proposed development during their autumnal migration, en route to wintering sites in Norfolk. The aim of this study is to - • Characterise the nature of pink-footed goose flights over and in the vicinity of the proposed Lincs/LID6 turbine array and • To experimentally extend the range of the bird detection radar to cover the entirety of the Lincs/LID6 offshore wind farm while not compromising data collection over the LID arrays. This latter consideration was considered critical in order that inter-annual comparisons of flight behaviour over LID would remain valid. 2011
