Relation between beach erosion and the development of coastal forest was investigated by comparing past aerial photographs, taking the Heisa-ura coast in Chiba Prefecture as the example. Sand dune has been well developed at this coast due to the strong wind-blown sand in winter in the past. In order to prevent the damage due to wind-blown sand, coastal forest has been extensively planted. However, excess development of coastal forest in recent years as well as the construction of earth dike along the coastal forest caused shoreline recession by the excavation of beach sand to supply the construction materials. Appropriate land management isrequired between the coastal forest area and the shore protection area in order to avoid devastation of natural sandy beach.
