The study was conducted in Siemianice, central Poland. In 1970-71 53 study plots were
established (20×20 m) by clear-cutting of an 81-year-old pine forest, and planted as monocultures
of 14 tree species: Abies alba, Acer pseudoplatanus, Acer platanoides, Betula pendula, Carpinus
betulus, Fagus silvatica, Larix decidua, Picea abies, Pinus sylvestris, Quercus robur, Tilia cordata,
Pinus nigra, Quercus rubra, Pseudotsuga menziesii, 3 or 6 repetitions for each. During 34
years of monoculture growth, the soil chemical conditions, ground flora composition and litter
decomposition rates differentiated strongly between some trees species. The aim of this study
was to check whether different tree species influence also the activity of soil fauna. In June and
October 2006, 50 bait-lamina were distributed in the centre of each study plot and exposed for
42 and 33 days respectively. While the soil fauna activities in monocultures of the same tree
species were similar, the soil animals appear more active in monocultures of Larix decidua and
Picea abies. Significantly higher was the soil fauna activity in summer than in autumn, although
soil moisture was lower in summer (12% at the beginning and 4% at the end of exposition) than
in autumn (10% and 12%, respectively). The main factor affecting seasonal differences in soil
fauna activity seams to be soil temperature which was significantly higher in summer (mean
19.3ºC) than in autumn (mean 10.1ºC). Observed were also differences in faunal activity in soil
profile with the highest activity at the depth of 0 ? 4 cm.
