Abstract

Stream-bank stabilization structures, or revetment, can impact riparian systems by confining watercourses to the point where natural functions are limited. Removal of existing revetment may have considerable impacts to stream-bank stability however. The effects of revetment and revetment removal on vegetation and stream-bank morphology were measured on three streams in forests dominated by Sequoia sempervirens (Coast Redwood) in northern California. Data were collected using randomly located transects on three treatments; “no-revetment,” “revetment-intact,” and “revetment removed.” Results were compared between treatments using ANOVA at a 0.05 level of significance. On all three sites, species richness, vegetation cover, and tree seedling density were found to be highest where no revetment existed compared to where revetment was intact. Stream depth and stream-bank slope were highest where revetment was intact. Recovery of vegetation following removal of revetment was more site specific being most pronounced where recovery time was greatest and stream-bank restoration efforts were highest.
