Adaptive management calls for identification, analysis and assessment on the context of river basin and nature. Small animals like badgers and foxes are typical natural habitats which originally inhabited the mountain area in Japan, but they have recently spread its habitat area to the human habitat including river embankment for flood management. Their burrow in the levee may raise the levee’s vulnerability because of the increase of seepage water through it. A field survey for their habitats shows the relationships between the natural habitat and river embankment, not only from morphological regime but also from biological and ecological connectivity, so it can enable to develop the ecological prediction map for the damage of their habitat. This study analyzes how to establish the adaptive management in a local basin and propose the practical guideline for ecologically sustainable river management in the field.
