Abstract

<p>In this study, we investigated the avian species composition at block parks in Kyoto City, and clarified variation of avian species composition appearing at block parks and environmental factors with distance from the large-scale habitats. As a result of the investigation, many urban avoiders and urban adapters appeared at block parks within 200m from large-scale habitat. Within 200-500m, urban avoiders decreased and urban adapters and urban exploiters mainly appeared. At block parks of more than 500m away, urban adapters decreased, and urban exploiters mainly appeared. At block parks within 250m from the large-scale habitats, the green coverage ratio within a small area around the block park had a positive effect on the urban avoiders. At block parks within 250-500m, the green coverage ratio in the block park had a positive effect on urban adapters. At block parks more than 500m away, the green coverage ratio within the wide area around the block park had a positive effect on urban avoiders. In order to improve avian species diversity, priority developments of block parks are improving the green coverage ratio in block parks in the area within 200-500m from the large-scale habitats and increasing the green coverage ratio within the wide area around the block park in the area more than 500m away.</p>
