| Abstract: | Landscape enhancement projects are under way at the Yamanakadani and Kadowaki rivers, which run through the campus of Hiroshima University, Japan. At both sites, the ecological value of land was determined from two aspects: (1) value as vegetation and (2) value to birds. To evaluate the vegetation, we selected conservation sites and suitable sites for enhancement considering rarity and recovery potential of vegetation, and access to users and construction equipment. We determined that the area of forest, the number of forest vertical layers, and forest pattern help sustain avian diversity and contribute toward the area functioning as an avian corridor. |
