Pollinator Conservation Resources – Pacific Northwest Region

The pollinator resources found on this page support habitat projects in Oregon, Washington, and British Columbia.

View all the regions in North America for other pollinator resources. For questions, comments, or to suggest additional content, please email pollinators@xerces.org.

For locally native wildflower seed to use in pollinator habitat restoration projects (including USDA-administered farm conservation programs), please see our Pollinator Conservation Seed Mixes. Xerces-approved seed mixes are free of systemic insecticides and developed using local eco-type seed by independent native plant nurseries for native plant restoration efforts.
