(Fig. 17a-b). The first classification (Jaccard) revealed two groups of habitats, the open and forest habitats. The second classification (Bray-Curtis) shows the complete separation of the beech forest from the other habitats. Apart from the different vegetation type, explanations for this phenomenon could be the higher altitude of the beech stand and the greater distance from the river, which can have a remarkable impact on soil conditions and, in consequence, on the Collembola communities. The second group contains the three lowland habitats. This group is further subdivided into two subgroups, separating the oak-esh-elm forest from the two open meadow habitats with relevant differences.

Conclusions

The Vasvár-Nagymákfa area is characterized by a rich Collembola fauna. With the sampling carried out in the 6th Hungarian Biodiversity Day the number of Collembola species known from the Őrség has almost doubled and, including the two species new to the Hungarian fauna (Tetracanthella pericarpatica and Arrhopalites acanthophthalmus), the number of recorded species in Hungary increased to 435.
