| Research Abstract |
Paddy abandonment has increased up to 10% of all agricultural area, and it caused drastic environmental change from watered area to grassland. We investigated species richness of adopted organisms in agricultural ecosystem of Akita prefecture, northern Japan. Our results supported that abandoned paddies under intermediate disturbance had positive effect for insects, frogs and birds inhabiting in paddy field. For forested animals, abandoned paddies without mowing had negative effects for disturbing its movements between forest and paddies. The impact of abandonment on biodiversity was able to control by adjusting succession stage of abandoned grassland and its spatial configuration.
