Flying vertebrates vs wind turbines

Flying vertebrates vs wind turbines Image

Wind energy, although recognised as a clean and environmentally friendly source of energy, can threaten flying vertebrates. There are several mechanisms that affect species, including mortality through collision with overhead structures, displacement, and habitat loss. To better understand the negative effects of wind energy development on species, we conducted several studies, varying from the development of spatially explicit models to predict areas of potential conflicts, to species-specific analyses of the main factors contributing to the risk.

The main objective of our research is to provide evidence-based recommendations to assist policy makers, wildlife managers, wind energy companies, and environmental consultants in their decisions and reduce the risk of new wind facilities being deployed in areas crucial for species conservation.
