Include Native Grasses and Wildflowers
Roadsides planted with native grasses and wildflowers support more butterflies and bees than roadsides dominated by non-native plants. In addition to providing roadside pollinator habitat, native plants can contribute significantly to soil stabilization, runoff reduction, and can contribute to reduced maintenance costs.
Reduce Mowing
Mowing of roadside vegetation beyond the shoulder during the growing season should be reduced, so wildflowers can be allowed to bloom. Consider mowing once a year in the dormant season or, better yet, mowing once every few years to reduce impact of mowing on pollinators and other wildlife such as songbirds.
Use Herbicides and Other Pesticides Sparingly
Blanket herbicide applications can eliminate wildflowers that pollinators depend upon. Spot-treat noxious weeds and carefully time herbicide applications to limit harm.
