This research will investigate the effects of White Alder recruitment on river channel geomorphology of the South Fork Eel River. White Alder (Alnus rhombifolia) exhibits periodic, large scale recruitment directly into the active river channel. Because of this, Alder has the potential to alter river channel processes such as bank erosion, depositon, and braiding through its effects on bank stability and water velocity. 24 cross-sections of the active river channel were surveyed in 2003 along a 4km stretch of the South Fork Eel River. Along each cross-section, Alder stand structure was characterized. A gradient of Alder stem densities was created by surveying sites with dense recruitment, dense recruitment suppressed by intense deer herbivory, and sites with sparse recruitment. The cross-sections will be re-surveyed in 2004, and changes in river channel geometry compared with Alder stand structure using regressions.
