We investigated blown sand and the revegetation process following severe damage to Japanese black pines caused by pine wilt disease in the Fukiage sand dune. We found that blown sand following severe damage tended to increase with increasing damage to Japanese black pine from pine wilt disease. Moreover, numbers of trees, tree species, total volume of tree trunks, Fisher-Williams'index of diversity and the void ratio of surface soil tended to decrease with increasing amounts of blown sand. Thus the difference of the revegetation condition affects greatly on the spatial distribution of the volume of blown sand.
