Summary There is Sawada wetland in Hitachi Seaside Park, and a rare dragonfly species inhabits in the wetland. In recent years, as the volume of spring water as decreased, therefore habitat has decreased. In this study, we made artificial ponds in Sawada wetland in order to preserve the dragonfly, and we have been monitoring the species in the wetland.
