Experiments are underway along the coast of North Carolina using sand fences and dune grasses to create and stabilize a barrier dune line parallel to and behind the existing beaches of low lying barrier islands. Several miles of experimental sections have been established, and their effectiveness in trapping wind-blown sand has been analyzed. Results to date (1968) show that sand fences and dune grasses will trap wind-blown sand and create a barrier dune. A vigorous, rapidly-growing strip of American beachgrass, 90 feet wide, will trap and retain all of the sand being transported by the wind in the area. Thus, a stabilized dune can be "grown" in the area using American beachgrass. Sand fences have been shown to be effective sand traps and can be used where satisfactory plants are not available or where it may not be feasible to await the establishment of vegetation. Two methods of using sand fences to create large dunes have been investigated; both are workable. The use of fabrics as sand fences has been investigated; their effectiveness varies with the porosity of the fabric.
