In secondary forests that have been abandoned, clear-cutting bamboo and thinning increase the species diversity of forest floor plants. However, the effects on ground beetles have not been sufficiently studied. In this study, we set up survey traps at four areas: Sasa (Pleioblastus chino) mowing area, Sasa standing area, bamboo (Phyllostachys edulis) clear-cutting area, and bamboo standing area in Tama hill, Kanagawa Prefecture, Japan. A total of 80 traps were set up to capture ground beetles: 10 traps in each area with two replicates. The number of species was greater in the case of management in the Sasa mowing area and bamboo clear-cutting area than in the case of no management in the Sasa standing area and bamboo standing area. In particular, the number of ground beetles was higher in the Sasa mowing area than in the Sasa standing area, bamboo clear-cutting area, and bamboo standing area. The ground beetles belonging to Pterididae were the most common, and the most common species were Carabus insulicola, Synuchus cycloderu, and Pterostichus yoritomus. In particular, C. insulicola comprised over 90% of the total ground beetles collected from the Sasa mowing area, suggesting that this beetle can be used as an indicator of biodiversity in an abandoned secondary forest.
