Evaluation of Potential Use of Vegetation for Erosion Abatement Along the Great Lakes Shoreline.
Abstract
The study identifies plants with potential, either alone or in combination with structures, to alter the erosion rate along shores of the Great Lakes. Information was obtained from literature, personal interviews, and a field survey. Shoreline plants were identified and evaluated. Thirty-three terrestrial species were found that effectively decreased surface erosion resulting from wind and runoff. No emergent or submergent plants were found to control erosion. While several emergent species may have special use in low-energy areas, the Great Lakes shores in the United States are generally not conducive to establishment of aquatic plants. Shores subject to wave erosion require structures or beach nourishment to attenuate wave energy. After the wave force is reduced by engineering techniques, vegetation will aid in controlling surface erosion. Subsurface seepage and soil slumping, which cause landslides and bank recession, can be prevented by dewatering glacial till; recession of sandy shores with steep banks can be controlled by bank resloping.
