Soil communities of enchytraeids and collembola (species composition, biomass), soil
respiration and activity of soil mesofauna were studied on transects between adjacent 34-year
old experimental monocultures (20×20 m) in Siemianice, Central Poland, including 8 tree
species: three conifers Pinus sylvestris, Picea abies, Larix decidua, and five deciduous Quercus
robur, Carpinus betulus, Fagus sylvatica, Acer platanoides, Tilia cordata. All species in 2 or 3
repetitions. Monocultures were planted on uniform sandy brown podzolic soil. Forty one samples
of soil (16.6 cm2, 10 cm deep) were taken using split soil corer at half-meter intervals along 20
m transects. Enchytraeide and Collembola were extracted from the soil using wet and dry funnels,
respectively. Soil chemical properties and the biomass of fine roots were also measured at
each station. Multivariate statistics was used to compare the faunal composition and soil
properties. The results demonstrate that the period of 34 years is not sufficient to allow for a
clear differentiation of faunal communities, although in some tree species (Tilia, Larix) strongly
affect mesofaunal species composition. Multivariate comparisons suggest that humus properties
and forest type (conifer vs. deciduous) seem to be major factors affecting faunal communities,
although soil chemical properties do not explain fully the whole variance observed. Soil respiration
rate and faunal activity (bait lamina) positively correlated with biomass and abundance of
enchytraeids. The patterns observed demonstrate a high repeatability.
