Birds being electrocuted may e.g. result in power outages and thus have an economic impact, and birds colliding with wind turbines or power lines may negatively affect the societal perception of and acceptance for renewable energy. The development of on- and offshore wind energy and associated power lines gives yet another perspective for knowledge needs, particularly in Norway, as the diverse and far reaching coastline, including the offshore archipelago and shallow waters, creates the most important Eur opean habitat for migrating and resident sea and coastal birds. The interaction between renewable energy systems and ecosystems raises major challenges for industry and society. Avian radar technology greatly extends the observation- and data-collection c apabilities for monitoring bird movements in adverse environmental settings, and experimentally investigating the effectiveness of mitigation measures. The infrastructure is envisioned to be directly employed within research activities directly tied to th e CEDREN projects BirdWind and OPTIPOL. It will thus facilitate high-priority research that is of widespread national and international interest. In addition, the infrastructure is aimed to be employed also in new CEDREN research activities (e.g. offshore wind energy). The principle objective of this infrastructure is to utilize the Mobile Avian Radar System for mapping bird activity and level-of-conflict connected to renewable energy. More specifically, the avian radar is aimed to: (1) identify areas and periods of high bird activity and migration fluxes, (2) identify factors contributing to collision risk between birds and man-made structures, and (3) test the efficacy of mitigation measures.
