DeBeque milkvetch (Astragalus debequaeus) is a small plant in the Fabaceae (Pea Family) that is known only from the Colorado River Valley in Delta, Garfield and Mesa counties, Colorado, and is considered to be imperiled at a global and state level (G2/S2; Colorado Natural Heritage Program 2014). One of the biggest conservation issues for this imperiled plant species is the lack of awareness of its existence and status. Avoiding or minimizing impacts to this species during road maintenance activities will effectively help to conserve its habitat and is unlikely to confer substantial impacts on road maintenance goals and projects. The Best Management Practices (BMPs) included in this document are intended to help increase the awareness of this species for anyone involved in road maintenance activities. The desired outcome of these recommended BMPs is to reduce significantly the impacts of road maintenance activities to the DeBeque milkvetch on federal, state, and/or private land. The BMPs listed here are intended to be iterative, and to evolve over time as additional information about the DeBeque milkvetch becomes available, or as road maintenance technologies develop. The intent of these BMPs is to inform people working along roadside areas regarding the importance of DeBeque milkvetch, one of Colorado's botanical treasures, and to outline some of the ways in which this species can coexist with road maintenance activities. The implementation of these recommendations will help to assure that maintenance activities proceed without unintended harm to these globally imperiled plants.
