6,233 spider species were obtained in the oak-hornbeam forests at seven study sites in the Malé Karpaty Mts. The spider communities of the oak-hornbeam forests were rich in species diversity. Trochosa terricola, Pardosa lugubris and Tenuiphantes mengei may be considered as the eudominant species. CCA analysis has proved the influence of undergrowth on the spider communities. The nominal variable - phragmentation did not influence the assemblages. We did not notice any negative influence of the lime dust on the spiders, except for the impact on species diversity. Migration of the spiders from the surrounding was noticed. The migration effect of the non-specific species was noticed in the spider community in the young oak-hornbeam forest. Being based on the analysis of the spiders we have specified spiders into four categories - leaders, typical spiders, specific spiders and tourist species.
