| Outline of Final Research Achievements |
To clarify how changes in urban forest characteristics, such as area, fragmentation and forest stand development, affect plant-animal interaction patterns, I investigated bird assemblage, its fruit removal, soil seed banks, and seedling dynamics at several forest stands at different developmental stages in an urban forested area of western Japan. I found that increasing structural complexity during forest stand development had a positive effect and was the most important for bird assemblage, which in turn influenced fruit removal and soil seed banks in this urban forested area. Seedling dynamics also suggested that establishment of seedlings from soil seed banks was likely to occur at the time of disturbance. Hence, a positive feedback mechanism is probably a component of plant-bird interactions during the development of forest stands in urban forested area.
