Fragments of woodland represent important natural and semi-natural elements that contribute to ecological stability and biodiversity in a landscape. In the Czech Republic, they are part of the Territorial System of Ecological Stability (TSES), which consists of bio-centers, bio-corridors, and interaction elements. The presence of fragments of woodland is of growing importance in the agricultural landscape, where they provide effective protection against soil erosion and serve as a refuge for many animals, whose presence is crucial in maintaining essential ecosystem functions. A functioning ecosystem is especially important in intensively farmed landscapes, which are exposed to frequent and heavy disturbance. Our aim was to evaluate the influence of certain habitat characteristics of fragments of woodland on the activity-density and species richness of selected groups of soil invertebrates (ground beetles, spiders, harvestmen, centipedes, millipedes, and isopods). The research was conducted in the agricultural landscape of South Moravia (Czech Republic) in the summers of 2016–2017, for which we used pitfall traps to collect soil invertebrates on preselected fragments of woodland. The results highlight a wide range of habitat preferences of individual groups of invertebrates, wherein it is not possible to clearly determine the most favorable environmental conditions for all organisms. Consequently, the priority should be to maintain the highest possible degree of heterogeneity among natural and semi-natural features, including with respect to their surrounding landscape. In addition, we found that due to their small size and width, fragments of woodland that are not included in the concept of bio-centers and bio-corridors can similarly support the activity-density and diversity of soil fauna.
