The Echinacea Project has been investigating tallgrass prairie in Douglas and Grant Counties, MN since 1995. Our research on native plants & pollinators identifies threats to prairies as well as conservation opportunities. For example, in a 21-year investigation of purple coneflower (Echinacea angustifolia) we found that prescribed burns improved seed production by synchronizing reproduction and improving pollination. We recently submitted a proposal to the Legislative-Citizen Commission on Minnesota Resources for funding to build on our long-term investigations. We propose research projects to investigate how prescribed burns affect solitary, ground-nesting bees — the most important pollinators in tallgrass prairie. Specifically, we will examine how burns affect solitary bee diversity, nesting habitat, and food resources (e.g. quantity and nutritional quality of pollen and nectar). This research will produce valuable information for natural resource managers, including guidelines for how to maintain insect pollinators and prairie plants with prescribed fires.

I love the video about “synchronized reproduction” and your poster. Good luck with your proposal! It will be good for the bees.
