Natural revegetation of debris avalanche and lahar (mudflow) deposits

Natural revegetation was studied on debris avalanche and mudflow deposits primarily northwest and southeast of Mount St. Helens on Forest Service land. Objectives were: 1) examine patterns of revegetation in response to large and small scale surface changes as deposits are modified by geomorphic processes; 2) characterize revegetation on different types of sites in the devastated area (North Fork Toutle River debris avalanche and Muddy River mudflow) and 3) establish a system of documented permanent plots to track ecosystem recovery and describe important processes through time.
