| Research Abstract |
This study aimed to clear the distribution structure and ecological characteristics of irrigation ponds in Saijyo Basin, Higashi-Hiroshima by using analysis of spatial statistics and predictive habitat models. The study cleared 1) four irrigation pond type (A~D) were recognized, 2) All the irrigation pond groups, except C, types were significantly aggregated within a 0.5-km radius, 3) Group C was aggregated, but did not show a distinct peak, 4) For the distribution correlation, groups A and C and C and D were significantly aggregated. Other irrigation pond groups were distributed independently. These results suggest that the spatial aggregation of species can be indicative of a positive interaction among them. Furthermore, we suggest that the spatial scale at which conservation methods are applied should be taken into account, and emphasize the need to consider spatial issues when developing strategies for pond conservation.
