The research was focused on the evaluation of habitat differences in the communities of small mammals of different habitats in the Moravian-Silesian Beskid Mountains. In the years 2007-2015 pitfall traps caught 4 819 individuals from 16 species. Small mammals were acquired on 38 permanent research plots. The results described the influence of stand conditions (species, canopy, herb, soil conditions), climatic factors (humidity, temperature), links to typological units (forest typology, edaphic categories, forest vegetation types) and management (commercial forests, protected areas) on small vertebrates. Small vertebrates were influenced by dominance, species diversity and evenness, degree of canopy cover and herbal species. The results were obtained by statistical methods. This study determined the environmental conditions affecting the appearance of yellow-necked mouse, wood mouse, bank vole, common shrew and pygmy shrew.
