| Abstract/Contents: | "Due to the dynamic nature and power involved in coastal erosion, large physical structures are usually required to prevent or minimize erosion. Occasionally, the nature and magnitude of the erosion allow for control with only vegetation. In 1983, the Alaska Plant Materials Center assisted the U.S. Air Force in a program to control wind erosion on Shemya in the western Aleutian Islands. Previously, standard seeding methods failed on two occasions. The site consisted of 11 hectares of bare beach sand exposed to winds in excess of 90 knots. This created a hazard as the area was adjacent to a strategic military runway. Drifting sand on the runway and jet engine damage was a major concern. Transplanting the local species of grass, beach wildrye, Leymus mollis, was determined to be the solution. Unfortunately, its use had never been attempted in Alaska. To control erosion, beach wildrye transplants were used in conjunction with seeding of red fescue, Festuca rubra, and Bering hairgrass, Deschapmsia beringensis. Within one year the problems were solved. The blowing sand no longer posed a hazard. Another site affected by serious sand erosion was on Adak in the central Aleutian Islands. The Plant Materials Center was once again asked to assist in controlling the erosion. The affected Naval facility was located 150 meters from the coast and adjacent to an active foredune that was damaged during facility construction. Beach wildrye was selected to solve the problem. This site was also subjected to severe winds. Within two years, the blowing sand problem was corrected and the foredune repaired. In other areas of Alaska, beach wildrye transplanting has been effective as an erosion control measure. Techniques for use have been developed and standardized to the point that the procedure is now being promoted as a normal practice for erosion control and restoration. The Alaska Plant Materials Center is considering other coastal species for use in coastal erosion control, but beach wildrye remains the preferred species." |
