Pollinator Habitat Benefits Agriculture

  • Economic analysis of wild pollinator

contribution to 10 major crops.

  • In nearly all cases and especially for

tomatoes, blueberries, melons, cucumbers, squash, apples, peaches, and bell peppers,

  • Gross revenues increase directly because of

the installation of pollinator habitat—and that’s even after subtracting out implementation costs.

Incomplete Pollination

  • 70% of crops

InSPIRE: Innovative Site Preparation and Impact Reductions on the Environment

§ Interest in restoration of ecosystem services of solar sites § What about pollinator services through maintenance of solar-pollinator habitat?

Agricultural Benefits of Solar-Pollinator Habitat

The establishment of regional flowering plants and soil preparation methods, either within the solar facility footprint area (e.g., beneath PV panels) and/or in

  • ffsite areas adjacent to the solar facility, that attract and support insect

pollinators.

“…will adopt pollinator-friendly solar standards...”

  • Once complete, these meadows, filled with native flowering

plants and grasses, will create as much bee and butterfly habitat as if 30,000 families were to each plant six-by-twelve-foot pollinator gardens.

What constitutes “pollinator-friendly” in the context of a solar array?

Flexible Standard

  • Percent wildflowers
  • Percent native species
  • Diversity of species
  • # seasons flowering
  • Nearby assets
  • Signage? Mgt plan?
  • Insecticide risk

Local solar project to turn land into pollinator haven

“EGP-NA saw the integration of a vegetation plan into the overall site design as an exciting opportunity to proactively support the local farming ecosystem and communities,” EGP-NA representatives wrote in an email interview. “For example, the Aurora solar project uses pollinator friendly seed mix and native plant species and wildlife which results in prairie grasses and flowers throughout the site that contribute to the growth of pollinator species

  • populations. These species like bees and monarch butterflies are critical to

supporting the pollination and production of local crops and the preservation and health of farmland and native landscapes.”
