Excerpt from Stabilizing Sand Dunes on the Pacific Coast With Woody PlantsFigure l. - Stabilized coastal sand dunes are used for recreation, provided pre caution is taken to preserve the permanent cover from damage.of extensive areas of eroding dunes on the north Pacific coast. They pointed out that trees and shrubs were essential to erosion control on some sites, while on others the choice between herbaceous and woody perennials for permanent stabilization depended on the use of the area. The land capability and the economic and social considerations determine the use of the stabilized area.Most of the dune areas on the Pacific coast of North America are in land-capability classes VII and VIII. 2 Such lands have severe limitation for use because of the erosion hazard, low fertility, or low water-supply capacity. Small areas of class VI land with slightly less erosion hazard and of excessively wet class V land are interspersed with the class VII and VIII land of the dunes. Small areas of class III and IV land occur on some coastal dunes. These may be used for cultivated crops or pasture, but they require large amounts of fertilizer and supplemental irrigation. If cultivated crops are grown, extreme precautions must be taken to prevent wind erosion.The same conditions that preclude the use of stabilized dunes for cultivated crops or pasture also limit their use for the production of major forest products such as lumber, poles, or pulpwood. Minor forest products such as Christmas trees, charcoal, and ¿orist greenery are possible with intensive culture when areas are near markets.The use of coastal dunes for recreation is consistent with both their land capability and their location. Large centers of population are usually located near the coast, and improved highways make them readily accessible to vacationers. Recreational use of coastal dune areas is enhanced by the proper use of trees and shrubs for permanent stabilization (fig. Precautions must be taken to preserve the permanent cover from damages by overuse, careless use, and fire.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
