Vegetation Vegetation description

Achillea millefolium Microsteris gracilis (Phacelia gracilis) Agoseris heterophylla Astragalus geyeri Using Rana to Document Plant-Insect Interactions • Pollination – essential for self-maintaining forb populations • Herbivory – attracting and supporting insect foods Rana video capture Forb seed collections for restoration Expected outcomes • Network interactions • Are they site-specific? • Key network components? Keystones? • Robustness? • Pollinator Support Evaluation • Comparison of Pollinator Support Indices between forb species and sites • Native forb seed collections nwf.org • Inform restoration forb seed mix • Site-specific restoration management (target plant taxa, increase forb and insect diversity, pollinator support, seed zones)
