In 1978 the U.S. Forest Service breached a dike on the north shore of the Salmon River estuary to reestablish a natural salt marsh in a diked pasture. Diane L. Mitchell, a graduate student at Oregon State University, initiated a detailed study of the restoration of the salt marsh ecosystem in 1977. In her work, completed in 1981, Mitchell collected base line data, established an intensive sampling system of permanent plots in the diked pasture and flanking 'intact' control marshes, and analyzed restoration progress from 1978 to 1980. This report continues Mitchell's earlier research by evaluating the composition, structure, function, and long term prospects for the restored wetland. It also summarizes the status of the restoration in 1988, eleven years after dike removal, and discusses prospects for total restoration to conditions prevailing prior to human alterations.
