Riparian Final Vegclass. Olympic National Park NRCA Westside Rivers Riparian Vegetation Project (2016)
Beschta and Ripple (2012) assert that increased elk populations in the Olympic National Park due to extirpation of wolves in the 1920’s has led to a reduction in riparian vegetation. They hypothesize that a decrease in this vegetation has led to an increase in erosion and undercutting of large conifer trees along the river banks, causing woody debris in the river, which in turn impacts channel morphology. Using imagery dating from 1939 and a set of digitized channel margins for each year, we classified vegetation changes that have occurred along the Hoh, Queets, and Quinault Rivers. We focused on identifying large conifers near the river that could impact water flow and channel morphology if undercut and classified...
