TY - RPRT TI - Using a Collision Risk Model to Assess Bird Collision Risks for Offshore Wind Farms AU - Band, B AB - This guidance has been prepared for The Crown Estate as part of the Strategic Ornithological Support Services programme, project SOSS- 02. It provides guidance for offshore wind farm developers, and their ecological consultants, on using a collision risk model to assess the bird collision risks presented by offshore windfarms.The guidance has been extended in this March 2012 version to make use of flight height distribution data, where that data is available and robust; and to include a methodology for considering birds on migration, for which survey data on flight activity may be limited.The guidance is accompanied bya Collision Risk Spreadsheet, which enables the calculations required to be undertaken and presented in a standardised mannera Worked Example, to illustrate the processa Tidal Variation spreadsheet, for use only when tidal effects may be significant DA - 2012/03// PY - 2012 SP - 62 PB - British Trust for Ornithology (BTO) LA - English KW - Wind Energy KW - Fixed Offshore Wind KW - Collision KW - Birds ER -
