Our research of ground entomofauna is related to the programme Intensive Forest Monitoring in Slovenia, location: Brdo pri Kranju. We monitored the species composition in two plots at secondary Scots pine forest sites: in one plot there was no anthropogenic influence (P1) while in the other monitored plot the Scots pine was cut down and the slash was spread over the soil and left in the plot (P2). We estimated the species diversity of five groups of arthropods: Acarina, Aranaea, Apterygota, Pterygota and Myriapoda. We monitored 11 orders of the Insecta class; we studied 13 families of beetles from the Coleoptera order. In general, the species diversity of arthropods wasgreater in the unaltered microhabitat (P1). The diversity of the ground entomofauna can be seen in stronger presence of thermophile species from the Cicindelidae, Cerambycidae and Cleridae families in the plot where the slash was spread over the soil (after having been ground) and left in the plot (P2).
