Abstract:

Construction of roads, railroads, pipelines and other facilities removes the native vegetation from sand dunes. As a result, sand movement starts and entire dunes may become active. This proposed method will permanently stabilize sand dunes by restablishing vegetation. The stabilization process includes grading, fertilizer application, seeding, mulching and anchoring the mulch to the sand. The paper gives guidelines for carrying out the process. The specific methods and materials that must be selected for each site's climate and the cost of the process are included, based on average conditions. Actual cost for a site is influenced by accessibility, topography, climate, cost of equipment use and labor. Alternate stabilization methods are also briefly discussed. Two case histories are presented in detail: one in Oregon, one in Alaska.
