BACKGROUND

Many pollinators are in decline and roadsides can be valuable habitat for them and other wildlife. Roadside managers have an interest in pollinator conservation and are seeking information about ways to support imperiled pollinators and to preclude future listings to the Endangered Species Act (ESA).

One of the primary goals of NCHRP Project 25-59, “Pollinator Habitat Conservation along Roadways,” was to produce guides that cover 16 regions of the United States. Each guide includes regional information about site selection, design, installation, and management of roadside pollinator habitat; the native plants and pollinators of each region; and guidance on ESA regulatory compliance to reduce regulatory uncertainty and contribute to pollinator conservation and recovery. Supporting materials that accompanied the guides include videos for transportation agencies and the public, a communications toolbox, monitoring and habitat assessment tools, and plant lists.

Efforts are needed to disseminate the research results of NCHRP Project 25-59, provide training on using the guides, and help state department of transportation (DOT) staff understand and consider pollinator habitat conservation strategies that may be effective in their jurisdiction or situation.

OBJECTIVE

The objective of this project is to help state DOTs to implement the guides developed by NCHRP Project 25-59 effectively.
