Location Narrative	CDPR and ACOE lands along the Yuba River: This is a distance survey of a Quercus wislizeni stand on the opposite bank of the Yuba River. The stand is mostly open with middle-aged, multi-stemmed Quercus wislizeni with emergent Pinus sabiniana of various ages and some Heteromeles arbutifolia in the understory. The herbaceous cover is mostly grasses, but it is difficult to identify species since they are all dry and far away.
