The project to be put out to tender, which is included in the Avifauna Protocols, seeks to minimize the mortality rates associated with birds hitting power lines. This project has been carried out in collaboration with non-governmental organizations (NGOs): Portuguese Society for the Study of Birds (SPEA), Quercus, Nature Protection League (LPN) and the Institute for the Conservation of Nature and Forests (ICNF), and the Technical Commission for Supervising Power Lines and Avifauna (CTALEA).
