ABSTRACT
We investigated forest floor cover, the amount of transported soil, and litter fall in a hinoki plantation adjacent to an evergreen broadleaf forest set as the shelterbelt on a ridge in order to evaluate the edge effect on surface soil conservation for the hinoki plantation by the litter from the shelterbelt. High values of broadleaf litter fall and forest floor cover, and a low value of transported soil, were observed closer to the edge. Generalized linear modeling suggested that transported soil was strongly affected by the forest floor cover, the percentage of which was largely dependent on the broadleaf litter fall, which was mainly determined by the distance from the edge. These results suggested that the direct supply of litter from the shelterbelt conserves the surface soil of the hinoki plantation around the forest edge.
