Natural revegetation of upland portions of the blast zone

Natural revegetation was studied within the northeast sector of the blast zone on Forest Service land. Objectives were: 1) compare revegetation on major disturbance types (pyroclastic flow, debris avalanche, blown down and standing dead forest); 2) examine the effects of pre-eruption plant communities and the presence/absence of snowpack on current vegetation; 3) establish a system of permanent plots to track ecosystem recovery and describe important processes through time.
