Transportation agencies can make a difference for imperiled pollinators by managing existing roadside vegetation and designing new revegetation plantings with habitat needs in mind. This can generate public support for the agency and help to mitigate the negative ecological effects of roads.
NCHRP Web-Only Document 362: Pollinator Habitat Conservation Along Roadways, Volume 2: California, from TRB's National Cooperative Highway Research Program, is part of a 16-volume series, with each volume focused on a specific region of the United States, and is intended to provide relevant guidance to rights-of-way owners and operators for roadside vegetation management practices that support pollinators, as well as strategies that are compliant with the federal Endangered Species Act.
