The influence of the site factors related to soil, forest stand and litter as well as to altitude, exposure and slope - on the composition/abundance structure of millipede communities (Diplopoda) was estimated. The research was carried out in 1999 to 2002 in 13 mixed oakhornbeam forest stands in Male Karpaty Mts. (South-Western Slovakia) ranged from 132 to 768 m a.s.l. In each locality, millipedes were collected by sieving of the litter taken at monthly intervals from 16 quadrates (25 x 25 cm) in each site. The redundancy analysis was applied. The most apparent influence on the community structure was ascertained for pH-value of litter and age of forest stand. Nitrogen content in litter was the most important factor, influencing the species richness of the millipede assemblages in studied sites.
