| Outline of Final Research Achievements |
Vegetation surveys and bird censuses were carried out in 71 stands located in eight urban parks in Tokyo Metropolis from December 2015 to July 2016. Wildlife conservation areas are placed in four of the eight parks. Avian species composition was analyzed by RDA, a constrained ordination methods. RDA with forward selection of constraining variables indicated that avian species composition showed significant correlation with coverage of leaf litter, coverage of lower vegetation, area of wooded part and way length to the nearest conservation area in the wintering season. In the breeding season coverage of leaf litter, area of wooded part, NDVI in surrounding area, number of passengers and species richness of plants in lower layers were suggested as significant variables. The results indicate that bird sanctuary and similar conservation areas can contribute to bird conservation even in urban areas. The important role of leaf litter to support avian lives was also suggested.
