Outline of Final Research Achievements

To establish operation system for sustainable management in the heavy snow fall region, I clarified the functional dynamics of ecosystem through the biological interaction with the manipulated field experiment in closedown skiing areas, bracken gardens, oak wilt stands, and abandonment fields. As a result, many successional stages distributed in the closedown skiing area, and the bracken garden was able to evaluate a function as rare grassy plain ecosystem. Oak wilt stands, and abandonment fields provided the new habitats where provide in stages of development of the lower vegetation. Based upon the foregoing, I was able to make clear that it maintained the local biological diversity concerned that various successional stages existed into a mosaic form by artificial management and the abandonment.
