To maintain Satoyama, labor-saving management styles have begun to be implemented. In contrast to the traditional styles based on labor-intensive practices such as rotational tree clear-cutting, the labor-saving styles consist mainly in tree thinning and ground vegetation cutting within a small spatial range. The consequences of this new approach are unclear, and our study aimed at filling this gap in our knowledge by analyzing the effects of small scale management on ground beetle community in suburban Satoyama (Kashiwa city, central Japan). We applied labor-saving management at limited spatial range, and sampled and analyzed ground beetles both before and after management. Cluster analysis revealed three groups of beetle assemblages, corresponding to three habitats: forest, bamboo stand and grassland. Comparison of wing traits showed that, before management, brachypterous beetles dominated forest plots and macropterous beetles were more prominent in the grassland plot, while in the bamboo stand both types of wing morphology were evenly represented. This trend can be linked to habitat structural stability driven by vegetation regeneration cycles which reflect dominant plant longevity. After management, macroptery increased in all three habitats. Probably, habitat disturbance created by vegetation management gave advantage to macropterous beetles over brachypterous beetles. These results suggest that wing type can be linked to vegetation structural stability. In some species, decline in abundance was accompanied with decline in body size. Our study shows that small scale Satoyama management can have pronounced effects on beetle assemblages.
