Impact assessment of deposit removal on the physical habitat for aquatic insects in the middle reach of the Yahagi River, central Honshu, Japan
タイトル（掲載誌）愛知工業大学研究報告 = Bulletin of Aichi Institute of Technology
一般注記We assessed the impact of deposit removal from the middle reach of the Yahagi River, central Honshu, Japan, on the physical habitat availability for five species of aquatic insects, viz., three dragonfly (Odonata) species, Macromia daimoji (Corduliidae), Gomphus postocularis (Gomphidae) and Onychogomphus viridicostus (Gomphidae); two stonefly (Plecoptera) species, Oyamia seminigra (Perlidae) and Neoperla (Perlidae), by employing the IFIM / PHABSIM. The weighted usable area (WUA) of the species that live in the cobble substrates with interstitial spaces, Onychogomphus viridicostus, Oyamia seminigra, and Neoperla, were expected to become wider in the estimated riverbed after the deposit removal than in the present riverbed. On the other hand, the WUA of the species that live on the mud and sand substrates in a backwater pool along the channel margin, Macromia daimoji and Gomphus postocularis, were expected to become smaller in the estimated riverbed after the deposit removal than in the present riverbed, if the gravel bar around the backwater pool would be removed. But, it was difficult to accurately assess the physical habitat in the places like the backwater pool after the deposit removal. Therefore, the practice of deposit removal work should follow the process of adaptive management in order to determine the best management strategy.
