What is PROGRESS?

The project PROGRESS is a joint venture between BioConsult SH, ARSU, IfAÖ and the University of Bielefeld. The aim is to determine collision rates of birds (of prey) with wind turbines and to establish background data for spatial planning including the prognosis and assessment of the collision risk with onshore wind turbines.

Search for collision victimsCollisions of birds (and bats) are a central field of conflict between the development of further wind energy use and nature conservation. Collision rates present an important aspect in the permission process, as several bird species and all bird of prey species are strictly protected by EU legislation.

Therefore, it has been the aim of this study to collect a representative dataset on collision rates of birds with onshore wind farms by conducting a systematic field study in several federal states of Northern Germany over the course of three years. To gather the data, line-transect searches for collision victims were conducted.

The actual collision rates were extrapolated from the field data using empirically determined correction factors (search efficiency, carcasss removal). Furthermore, bird behavior observations in existing windfarms were also taken into account to evaluate the collision risk. On top of this, the influence of the additional mortality was to be modelled, in order to address the question of how relevant it is on the population level.
