Yes, getting Arroyo Willow (Salix lasiolepis) hedgerows established in Almond fields should be a huge help. Lot of the Almond is on broken land on the fringe of the valley, and has drainages that run through. These have been "cleared" of veg, but we need to let the willow come back and fill those ephemeral streams. Salix has nectar that is 50% sugar, and as a catkin (wind pollinated) flower structure has abundant pollen. Blooms January-March on the coast, and about Almond season in the SJ valley.
Local secret: when the truckloads of migratory bees come to the coast to condition for the Almonds, the yards with Arroyo Willow thickets for December-January brood buildup are the ones that fire up. The Blue Gum Eucalyptus yards, not so much. Euk is only 13% sugar, and I think it discourages the brood build out - too watery. Of course most of the migratory bees just slap on a paint pail of syrup and a roll of sub.
