The similarity of the forest structure between a revegetated slope established by natural planting technique about 20 years ago and the surrounding natural forest

Abstract

In order to evaluate the similarity between two slopes in Takayama city, we investigated the forest structures between a revegetated slope by natural planting technique developed about 20 years ago and the surrounding natural forest. According to the tree census, the revegetated slope was in initial successional stage and the natural forest was in late stage. Therefore, little similarity was found between the two sites. However, seedlings detected in the natural forest were observed in the understory of the revegetated slope. Hence, if succession proceeds, the vegetation will become the same vegetation as that found in the natural forest.
