Description: Riparian communities established along Elder Creek, a tributary of the upper South Fork Eel River, are bounded by two frequencies of periodic flooding. The upper limit for the riparian zone occurs at bankfull stage. The lower riparian limit is associated with a more frequent stage height, called the active channel, having an exceedance probability of 11 percent on a daily average flow duration curve. Distinct tree communities occupy bankfull and active channel zones. Riparian densities (trees per meter of stream channel) along the active channel decreased with increasing channel gradient and curvature. Riparian densities at bankfull stage were not as sensitive to change in channel gradient and curvature.
