This report contained following items described by respective researchers participated in this project.1. Research objectives : Following items such as population genetics of natural beech forests using isozyme analysis, climatic and edaphic evaluation of isozyme study site condition of beech forests, natural regeneration by seed and sprout were studied. Then, landscape analysis of beech forests was made, and from the view points of fauna and flora protection and of ecological genetics, conservation of genetic resources and raising management of the beech forests were integratively discussed.2.
