The technical development in the wind power industry is constantly advancing with an increasing number of new turbine types. Therefore, the conflict potential for nature conservation must also be continuously re-evaluated. The threat to wind energy sensitive birds and bats depends to a large extent on the choice of location for the turbines. How the conflict potential is to be assessed with further increasing turbine height – or also with decreasing turbine height and increasing rotor area – has not yet been sufficiently described. Against this background, the project aims to analyse the potential impact in connection with the available avoidance measures and to identify options for action. Detailed research and information gathering for all German regions delivers the basis of the assessment.
While the average rotor diameter of wind turbines in Germany continues to increase, different tower and power output configurations can be designed at the same time. Depending on the chosen turbine configuration, the distance between the rotor tip and vegetation can narrow down. At the same time, more and more small wind turbines are entering the market. Thus, depending on the turbine type, impacts on the activity areas of many bird and bat species vary, which can change the general collision risk.
The following questions play an important role in the project:
Aims of the study:
Within the framework of the project, new developments are to be researched in close coordination with the Federal Agency of Nature Conservation, which will then be presented and evaluated from a nature conservation perspective. To this end, it is necessary to obtain information from the federal states, including planning documents, publications and initial findings. The results and open questions are to be discussed with experts (including ornithological institutions) and subsequently published.
