The PROGRESS project aimed to determine collision rates of birds (of prey) and to establish planning-related recommendations to estimate and assess the risk that birds collide with wind turbines.
Field research project on bird collision rates at wind turbines
Bird (and bat) collisions are considered a key area of conflict between further development of wind energy use and nature conservation. As numerous bird species and all bird of prey species are strictly protected under EU legislation, collisions represent a legally important species conservation aspect in approval procedures.
Aim of the project therefore was to collect representative data on collision rates of birds with onshore wind turbines in several North German federal states in a systematic field research project over three years. Line transect searches for collision victims were carried out on a regular basis.
The actual number of collision victims was calculated including experimentally determined correction factors. Behavioural observations of birds were additionally included in the assessment of a risk of collision with existing wind turbines. Furthermore, modelling of the influence of additional mortality was used to address a possible significance on population level.
The PROGRESS project was successfully completed in June 2016. The PROGRESS team would like to express our heartfelt thanks to all those who have contributed to, supported or accompanied the project.
