Electricity networks

Electricity networks

Networks for electricity distribution (the grid) constitute obstacles (aerial cables, pylon structures with risk of electrocution) that can threat flying animals, such as birds and bats. We have carried out research on the impact of electrocution on the eagle owl, which is heavily impacted by electrocution throughout Europe. Our research results and recommendations provide guidance for conservation managers and electricity compagnies who deploy measures for mitigating the impact of this infrastructure so as to lower mortality risks.
