(2005) document on the use of remote techniques for ornithological monitoring for offshore windfarm studies. However, Desholm et al. (2005) did not provide offshore windfarm developers with clear and practical guidance on the ‘best practice’ application of remote techniques for effectively observing the behaviour of target bird species. In the UK, ‘best practice’ guidance to highlight appropriate remote techniques for assessing behaviour of individual target species, or groups of species, has been much needed. Consequently, the implementation of remote techniques in ornithological assessments within Environmental Impact Assessments (EIA) was variable during Round 1 (R1) and Round 2 (R2) in the UK.The aim of this report was not to re-iterate technical information contained within the original COWRIE report but to provide clear ‘best practice’ guidance. Our aim is to ensure that this guidance is applicable for ornithological assessments made within the planning and EIA process for the STWR and R3in the UK.

However, they are only part of the solution in terms of effective monitoring in a scientifically rigorous and integrated manner. It is important that they are neither regarded as default techniques nor, alternatively, as methods to be ignored by developers because of their apparent novelty or cost. Remote techniques should be integrated effectively with existing methods to enable timely and comprehensive EIA as well as pre and post construction monitoring. In particular, they offer much utility for collecting data that other techniques simply cannot accomplish. Issues surrounding mass movements in low visibility, darkness and over large spatial scales or temporal periods can all be overcome by remote techniques. Tagging studies can provide direct individual based data from birds from which to refine understanding of potential impacts, enabling better-informed assessments. The consortium has been keen to stress the importance of an integrated approach to all bird monitoring at offshore windfarms (through an IOMP concept) as part of the STWR and R3 process. Therefore, dependent on the location of the proposed site/zone and the bird species present (and the behaviours which may place them at risk from the presence of an offshore windfarm), remote techniques have a particular role to play. The integrated monitoring requirements for a site or zone can be usefully mapped out within the simple framework (Section 2.4) proposed by the consortium, in order to determine the contribution which remote techniques can make to the overall ornithological assessment. Remote techniques should always be viewed as complementary to, rather than a replacement of standard survey techniques (notably aerial and boat-based surveying) and modelling (e.g. population viability analysis, collision risks analysis etc.).
