Insect populations flourish in the restored habitats of solar energy facilities

Bumblebees buzz from flower to flower, stopping for a moment under a clear blue Minnesota sky. Birds chirp, and tall grasses blow in the breeze. This isn't a scene from a pristine nature preserve or national park. It is nestled between photovoltaic (PV) solar arrays on rehabilitated farmland.

Researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory and National Renewable Energy Laboratory wanted to understand the ecological value of PV solar energy sites planted with native grasses and wildflowers. They examined how vegetation would establish and how insect communities would respond to the newly established habitat. The five-year field study published in Environmental Research Letters looked at two solar sites in southern Minnesota operated by Enel Green Power North America. Both sites were built on retired agricultural land.

"This research highlights the relatively rapid insect community responses to habitat restoration at solar energy sites," said Lee Walston, an Argonne landscape ecologist and environmental scientist who was lead author of the study. "It demonstrates, if properly sited, habitat-friendly solar energy can be a feasible way to safeguard insect populations and can improve the pollination services in adjacent agricultural fields." Walston also serves as head of the Ecology, Natural Resources, and Managed Systems department in Argonne's Environmental Science division.
