There are only few studies that explore the ecological consequences of forest management on several organism groups. We studied the short-term effects of four forestry treatments including preparation cutting, clear-cutting, retention tree group and gap-cutting in a temperate managed forest on the assemblage structure of understory plants, enchytraeid worms, spiders and ground beetles. Here we show, that the effect of treatments on the different facets of assemblage structure was taxon-specific. Clear-cutting and retention tree group strongly impoverished enchytraeids assemblages. Even if the species richness and cover of plants increased in clear-cutting and gap-cutting, their species composition moderately changed after treatments. For spiders only their species composition was influenced by the treatments, while the response of ground beetles was slightly affected. Short-term effect of forest management interventions on biodiversity might be compensated by the dispersal (spiders, ground beetles) and resilience (plants) of organism groups, however sedentary soil organism showed high sensitivity.
只有少数研究探讨了森林管理对多个生物群体的生态后果。我们研究了温带管理森林中的四种林业处理（包括预备砍伐、皆伐、保留树木群和林窗砍伐）对林下植物、线蚓类蠕虫、蜘蛛和步甲类甲虫组合结构的短期影响。在这里，我们表明，处理对组合结构不同方面的影响是分类群特异性的。皆伐和保留树木群强烈减少了线蚓类蠕虫的群落。即使在皆伐和林窗砍伐中植物的物种丰富度和盖度增加，它们的物种组成在处理后也会适度变化。对于蜘蛛来说，只有它们的物种组成受到处理的影响，而步甲类甲虫的反应则受到轻微影响。然而，生物多样性的森林管理干预的短期影响可能会被生物群体的扩散（蜘蛛、步甲类甲虫）和恢复力（植物）所补偿，但是固着土壤生物表现出高度的敏感性。
