At 9:30 a.m. tomorrow on Tuesday, June 11, Rosemary Baker will be presenting her Master of Environmental Horticulture research in the Douglass Classroom at the Center for Urban Horticulture (CUH): “Elwha Revegetation Project: 2012 Lake Aldwell Seeding Trials.”
Landmark restoration of the Elwha River by the Olympic National Park and Lower Elwha Klallam Tribe began in 2011 and involves planting native woody trees, shrubs, grasses and forbs throughout two recently exposed reservoirs. Revegetating by direct seed application supplements these efforts and is intended to speed ecosystem processes by quickly adding organic matter and building soils on fine and coarse glacial sediments. Revegetation efforts are expected to reduce sediment erosion on valley walls and terraces and assist in the natural succession process within the context of restoring relatively pristine riparian habitat for the return of salmonids following a 100-year absence from the Elwha River.
Practical seeding methods and several species mixes were tested on the shoreline of former Lake Aldwell in 2012 and monitored for successful germination, initial growth and resulting stand densities through the summer drought period. Colonization by priority weeds and native tree and shrub recruitment was also assessed.
So make your way to CUH to hear Baker talk about her work during the past two years and its context within the restoration of the Elwha River. All are welcome!
