I live here in central coast of california and spend a lot of time in humboldt and the sierras, from all my wondering around california my favorite arrow shaft material is mock orange and hazelnut, ocean sparay, viburnum, red osier, chokecherry and wild rose. In that order as well except for mock orange and hazel nut which are tied for first. A good place to look for arrow shaft material is along river and creek banks. I find a lot of good stuff down here especially on north slopes of hills. the red osier is the stuff that grows along creek and river banks that turns red during the winter and losses its leaves. Current can also be used for arrow shafts as well as snow berry. look for shafts as thick as your thumb at the base with few nots and no kinks. good luck and have fun. I have a bad addiction on not being able to pass up good arrow shoots and have a little over a hundred in different stages of production.
