A Summary of Bird Mortality at Photovoltaic Utility Scale Solar Facilities in the Southwestern U.S.

This summary provides a comprehensive overview of bird mortality patterns in utility scale photovoltaic solar. It synthesizes results from fatality monitoring studies at 10 photovoltaic solar facilities across 13 site years in California and Nevada. The report also addresses vegetation that is often removed in regions such as deserts in the southwestern U.S. However, the benefits of site restoration to pollinators and other wildlife have been recently recognized and developers in some regions of the U.S. are moving towards ecologically-based site restoration and low impact site restoration.
