In this study, the effects of vegetation and elevation on the distribution of the endangered tiger beetle larvae were examined in a sandy shore created for the purpose of mitigation. We found that the following four facts. 1) The habitable area for their larvae has been decreasing year by year. 2) The process of making shore slopes is different depending on the location. 3) Seaside plants newly occurred at the elevation where the larvae prefer. 4) No larva was found at the area with dense vegetation. Therefore, the advancement and overgrowth of coastal vegetation were considered to be the major factors that reduced larval distributions in the created shore. So, we suggest the following two plans for the adaptive management. 1) Removal of seaside vegetation and control of the tip of vegetation. 2) Maintenance of habitat area by raising the ground level.
