Guide to Good Practices for Conducting Fauna Studies in Photovoltaic Solar Plant Installation Projects and Environmental Measures

From Biodiversity Node, in collaboration with the Ministry for Ecological Transition and the Demographic Challenge (MITECO), we have developed “Guide to Good Practices for Conducting Fauna Studies in Photovoltaic Solar Plant Installation Projects and Environmental Measures”

It has been carried out by Rodrigo Fernández-Mellado, Eladio L. García de la Morena, Elena Baonza Díaz, Jon Domínguez del Valle and Cristina Acosta Gallo , under the direction and coordination of Luis Benavente Fournier, from the Subdirectorate General of Terrestrial and Marine Biodiversity of MITECO, and the participation of Ángel Luis Sánchez Fernández, Montse Reina Nieves, Miguel Ángel Blasco Rodríguez, Begoña Álvarez Cabello and Teresa Pereyra.

This white paper provides practical, evidence-based recommendations for assessing, preventing and mitigating the environmental impacts of these projects. Highlights include:

  • Evaluation Methodologies: Detailed procedures for studying different faunal groups (birds, bats, terrestrial mammals, among others).
  • Environmental Measures: Strategies to avoid, minimize, and compensate for impacts on biodiversity.
  • Practical Cases: Examples of measures applied in real projects, along with analyses of their effectiveness.
  • Monitoring Program: Guidelines to ensure the proper implementation and evaluation of the proposed measures.
