Description
<p> This paper addresses the effect of revegetation on forest soil development and water infiltration rates in the shallow landslide scars of slopes covered by volcanic ash and pumice fall. The number of trees and tree species peaked approximately 10 years after the occurrence of the shallow landslides, and then declined with time. Approximately 40 years after the occurrence of the landslides, an apparent steady state was achieved. Based on the temporal variation of the Fisher-Williams' index of diversity, the forest located in the shallow landslide scars reached a climax approximately 40 years after the occurrence of the landslides. Revegetation developed on the forest soil and had grown to a thickness of approximately 40 cm by the time the forest reached a climax approximately 40 years after the landslides. After 58 years, the water infiltration rates and forest soil thickness in the shallow landslide scars were approximately 70 and 65 %, respectively, compared with those measured in the headwater forest of broad-leaf trees.</p>
