Author Location ? South Yuba River State Park
Location Narrative ? CDPR and ACOE lands along the Yuba River: This stand is located on the SE bank of the North Yuba River at Point Defiance, and is almost entirely under several feet of water. The stand is at the edge of a campground and the impacts resulting from that are unknown. The photos and GPS point were taken at the eastern edge of the stand. The stand is dominated by mature Salix laevigata with some Salix exigua mixed in. There is some Rubus discolor, but mostly on the eastern edge of the stand. The soil texture is unknown since the substrate is underwater.
