Against this background, the different approaches to assessing significance in connection with wind energy development and birds are the focus of the R+D project "Birds and wind energy use: best practice examples and planning approaches to conflict resolution". With a view to the case law, requirements for the assessment of significance are first derived. Based on this, the currently available methodological approaches for assessing the "significantly increased risk of killing" are recorded and classified. The existing approaches for a possible species protection exemption procedure according to § 45 para. 7 BNatSchG are also presented and assessed. In addition, recommendations are formulated both for the significance assessment and for the exception as to how any existing deficits in the previous approaches can be remedied or in which areas further development is required.
