Conserving Roadside Populations of Colorado’s Globally Imperiled Plants

At least 22 globally imperiled plants found along roadside areas in Colorado are at risk of
extinction. One of the biggest conservation issues for Colorado rare native plants is the lack of awareness of their existence and status. CNHP partnered with the Colorado Department of Transportation (CDOT) and Colorado Natural Areas Program (CNAP) for a pilot project to explore how road maintenance activities might proceed while minimizing impacts to rare plants.  Avoiding or minimizing impacts to these species during road maintenance activities may help to effectively conserve their habitat.

To learn more about this pilot project, take a look at the final report.

The species-specific Best Management Practices (BMPs) which complement this document are intended to help increase the awareness of these species for anyone involved in road maintenance activities. The desired outcome of this report and the associated recommended BMPs is to significantly reduce the impacts of road maintenance activities to ten globally imperiled plants on federal, state, and/or private land, while still addressing roadside safety concerns.
