Pollinators are essential to our health and to the health of ecosystems. However, pollinators are in trouble. With more than 17 million acres of land in roadsides in the United States alone, transportation rights-of-way are a significant, yet often overlooked, resource for pollinator conservation. Many of these roadway environments offer excellent opportunities to increase pollinator habitats. Landscape architects with transportation agencies across the country can take steps to improve the quality of roadside vegetation to benefit pollinators, steps that can also maintain public safety and improve public good will. Presenters will discuss roadsides, roadside design, and roadside vegetation management and how these affect the establishment and sustainability of pollinator habitats. An overview of best management practices will be provided, as well as a summary of resources for practitioners. Presenters will provide perspectives covering the eastern forest, arid southwest, and central prairies.
