1) The breeding biology of the Great Basin wildflower Chaenactis douglasii will be characterized experimentally to inform prospective seed growers of this plant’s pollination needs when farming it to produce restoration seed. 2) The post-fire fates of native bee communities across the northern Great Basin will be sampled from a chronosequence of past wildfires. This knowledge is important for the reproductive success of large seedings of wildflowers meant to rehabilitate recently burned sage-steppe and juniper habitats.
1) The breeding biology of C. douglasii will be studied in a common garden by comparing achene and seed sets at caged flowers, openly visited flowers, and manually self- and cross-pollinated flowers in our common garden. Combined with flower production, we can then estimate seed production per plant by each treatment. 2) A chronosequence of accessible large Great Basin wildfires will be visited during spring bloom and the bee faunas of 1-2 target wildflower species will be quantitatively sampled in and outside of the fire perimeter. Bloom density, forb diversity, shrub density and densities of the dominant wildflowers will be characterized by standard plant community measures.
