Pollinator-focused solar parks

Researchers in the US ascertained that the partial shading provided by solar parks creates a microclimate that favors the abundant growth of more varied flowers and pollinators. They also found that partial shading increases bloom abundance by delaying bloom timing, increasing forage for pollinators during the hot and dry late season.
