Some people in Cedar Rapids, Iowa, are seeding bee-friendly open space "with native prairie grasses and wildflowers, plants that will both nourish pollinators and prevent invasive weeds from spreading. So far, the initiative has secured $180,000 in funding from the state and the Monarch Research Project, an organization dedicated to restoring monarch butterfly populations and pollinator habitats."
The EcoWatch article tells you how you can "replicate the Cedar Rapids experiment in your own backyard."
A Science article from the American Association for the Advancement of Science reveals that other people are researching whether hummingbird-size drones can replace butterflies and bees.
Both articles are from February 2017.
