Recovery following experimental removal of rockweed along rocky shorelines was monitored at five study sites in Washington and Alaska. Rockweed plants were cleared from experimental plots using methods that simulate cleanup techniques applied to rocky shorelines that have been affected by oil spills. Three treatments were evaluated: removal of rockweed only, complete removal of rockweed and all other biota, and an undisturbed control. One year after treatment, results indicate that the percent cover of rockweed remained lower at treated plots compared to control plots, and was lowest where all biota had been totally cleared.
