Solar Farms on Peatlands Boost Bird Diversity in Germany

Researchers in Germany found that solar parks built on restored peatlands host a more diverse bird community than nearby drained farmland. A study led by Hanna Rae Martens at the University of Greifswald tracked bird species at a solar park and adjacent grassland during the 2024 breeding season, using audio recorders to identify birds by their calls.

The solar park attracted both wetland species like the endangered meadow pipit and species not typically found in peatlands, suggesting the panels provide valuable habitat. The findings indicate a potential synergy between peatland restoration, important for carbon storage and climate mitigation, and renewable energy production.

Drained peatlands contribute significantly to greenhouse gas emissions, accounting for 37% of Germany’s agricultural emissions and 5% of global anthropogenic emissions. While the study has limitations, including close spacing of recording devices and a lack of comparison to a rewetted peatland without solar panels, it offers promising insights. Martens is now expanding her research to additional sites to investigate how solar panel design influences bird populations.
