In order that reclamation forests which utilized the trees and forest topsoil lost by development of a woodland might verify whether it recovers to the forest ecosystem which was similar with the natural forest, the soil fauna were taken up as an evaluation index of forest. The two survey sites, which are the topsoil transplant sites and the trees transplant sites, are adopted for the monitoring. Although the change of the soil fauna in these survey sites that has decreased within 1 and / or 2years, it become the composition of the soil animal group which has recovered gradually. It was also similar with the natural forest after 4 years from the transplant. Moreover, the soil fauna was also shown for increasing in the man-made land soil for planting of the trees transplant sites of the herb dominance. It turns out that the soil fauna is closely connected with the changes of vegetation cover of above-ground part. These changes are the change of cover degree of the upper story by the survival conditions of the transplanted trees, and increase in the floor vegetation by growth of pioneer tree species and herb's invasion.
