Annual Grassland

Annual grassland dominates the uplands in the managed pastures/fallow agricultural areas and on mima mounds within the less disturbed, more natural areas of the bank site. The dominant grasses include annual fescue (Vulpia myuros) and medusa-head (Taeniatherum caput-medusae) interspersed with stands of wild oats (Avena barbata and A. fatua) and ripgut brome (Bromus diandrus). Native species in this habitat, such as Johnny-jump-up (Viola pedunculata), yarrow (Achillea millefolium), common lomatium (Lomatium utriculatum), blue-dicks (Dichelostemma capitatum ssp. capitatum), and checker-bloom (Sidalcea malvaeflora) occur singly or in small colonies. Lowland shooting-star (Dodecatheon clevelandii ssp. patulum), yarrow, and Johnny- jump-up are native plants that occur sparsely on some of the uplands and mounds.

Species credits for the uplands (Group 5) include:

  • Swainson's Hawk (foraging)
  • Burrowing owl (nesting and foraging)
  • California tiger salamander (upland)
