2008-2009, ECON Ecological Consulting Ltd., Quantifying the relative use of coastal waters by breeding terns: towards effective tools for planning and assessing the ornithological impact of offshore wind farms series https://portal.medin.org.uk/portal/start.php?tpc=015_0641f678-1ef8-4e6a-a073-33a21cff3a52 The potential impact of the development of offshore wind farms (OWFs) upon seabird populations is a key issue within the current debate on sustainable energy provision. Terns, (Sterna spp. and Sternula albifrons), especially when on their breeding grounds, have emerged as sensitive receptors in many consented and planned OWF projects. To date, information on the interaction of terns with OWFs has remained scant due to a lack of understanding of the foraging ecology of terns especially at specific sites and the inability of standard assessment tools to define the relative use of specific areas by foraging terns. The current project aimed to advance the use of a series of methodological and assessment tools, some of which were initially developed in the Greater Wash SEA area (funded by Centrica/AMEC) with others developed specifically in this project. In essence, this involved a move towards an individual-based approach. 20071001 20070101
