Technical Abstract: Federal land managers desire seed of Great Basin perennial wildflowers, mixed with grass and shrub seed, to rehabilitate millions of acres of rangelands degraded by altered wildfire regimes, overgrazing and exotic grasses and forbs. At stake are half the nation’s sagebrush communities. Only farmed seed crops can reliably supply the annual need for tons of affordable, clean seed. Fifteen candidate wildflowers are highlighted. Their pollination needs are being experimentally evaluated, their bee faunas regionally surveyed, and progress made toward practical pollinator management options for growers. The wildflowers range from fully self-fertile to largely outcrossing. Only Crepis acuminata sets much seed without pollinators. Bees dominate the pollinator guilds of 14 of these wildflowers. Blooming Lomatium and Sphaeralcea predominantly host ground-nesting oligolectic bees. Honey bees or alfalfa leaf-cutting bees pollinate the two Dalea species. Some guilds include 1-2 bee genera with potentially manageable cavity-nesting species, especially diverse Osmia. Populations of 3 native Osmia bees with pollination promise have been obtained, evaluated, and management protocols developed to accommodate their nesting habits. Two are being increased from hundreds to thousands to pollinate legume seed crops (Hedysarum, Astragalus) slated for production.
