THE CREATION AND MANAGEMENT OF HABITAT FOR TIGER BEETLE IN CREATED SANDY SHORE

Abstract

 In this study, the effect of elevation, vegetation and sediment stability of habitat for the endangered tiger beetle larvae were examined in a sandy shore created for the purpose of mitigation for the loss of their original habitats. We found that the following three requirements of larvae. 1) The elevation of habitat was within a range of T.P. 0.7m - 1.0m. 2) The vegetation was under 25%. 3) The coefficient of variation for sediment stability was under 6.7%. We extracted the locations that correspond with these three conditions of the habitat by GIS analysis and found a place suitable to the larval habitat. We propose the creation method for the larval habitat that is a vegetation removal, making relatively small impact on the environment and securing a large area.
