Pollinating insect populations are declining. As a result, there is increased interest in protecting pollinators along roadways. Several insect pollinators have been petitioned or listed under the Endangered Species Act. Many of these have had limited distributions, but more widespread species are now being considered. State DOTs face uncertainty in practices to best design and maintain roadsides to conserve species and, in cases of listed species, comply with the Endangered Species Act. This project would compile information on current and previous conservation and compliance strategies and practices across the US to inform state DOTs as they determine how best to conserve and maintain roadside pollinator habitat.
