In this paper the effect of different methods of soil scarification in a clear−cut area were studied. The following soil preparation techniques were applied: the soil cutter, the active soil plough, the traditional method with use of LPz plough, and the manual scarification of soil in circles surrounding the stem of the future young tree. The effect of management of the residual heaps of branches was also tested. Branches were either put in prisms in the original shape or, having been previously chipped, equally distributed over the entire area of the clear−cut. Additional studies focused on the effect of the time of clear−cut execution (winter or summer) on the condition of epigeic carabid communities. The least regressive effect to analysed communities was observed after the application of the point manual soil scarification. The clear−cuts carried out during the winter season, to a greater degree, favours the forest carabid fauna, preserving them in a structure more resembling the forest communities. More distinctive positive effect on the carabids is observed after putting the residual heaps of branches in prisms; the latter gives shelter for the carabid fauna and constitutes the refuge spots for it.
