Meeting Agenda ......................................................................... :..................................... 199 iv r INTRODUCTION Government regulators, scientists, and other stakeholders met in May 1998 to discuss research and regulatory approaches that could be helpful in predicting, measuring, and reducing the numbers of birds killed by collisions with wind turbines. This meeting was the third in a series that the Avian Subcommit tee of the National Wind Coordinating Committee (NWCC) has convened as part of the Subcommittee's efforts to address and build consensus on issues of public policy, scientific research, and stakeholder/ public involvement related to avian/wind power interactions. The Proceedings of the first two meetings, held in 1994 and 1995, were published in 1995 and 1996, respectively. They can be accessed on the NWCC's website, as described on page (ii) of this volume. Meeting I: The first meeting, held in the Denver area in July 1994, occurred at a time when there was much controversy about bird/wind power interactions, especially in California. That meeting was convened to focus on the research aspects, particularly to (1) identify and prioritize key issues, (2) define a research agenda to resolve scientific and technical issues, while (3) insuring transferability of results, (4) avoiding duplication and inadequate science, and (5) building consensus on approaches to the research needed to address the issues. The meeting was organized by groups with many perspectives, including the National Renewable Energy Laboratory (NREL), the Department of Energy (DoE), American Wind Energy Association (AWEA), National Audubon Society (NAS) , Electric Power Research Institute (EPRI), and Union of Concerned Scientists (DCS). The first meeting was attended by about 57 individuals representing those and other groups, plus various independent scientists with relevant expertise. They reviewed the status of wind power in the U.S.A., developed lists of research questions, reviewed past and ongoing avian research at wind plants in the U.S.A. and Europe, discussed design concepts for this type of research (including Adaptive Resource Management), discussed desirable components of an integrated national research program, and identified a
