The paper develops the transformation of the species composition in the Baraní district according to the intensity of management and the extent of Norway spruce decline. The Baraní district is located in the Moravian-Silesian Beskydy Mountains, the predominant site is characterised by rich soil of fir-beech vegetation zone, and spruce is represented by 83%. With the standard approach and the current extent of clearings, 3.4 ha are converted annually (of which 1.9 ha on the clearings and 1.5 as underplanting). The low-cost approach and the intensive approach convert 1 ha and 5.3 and 10.1 ha, respectively. For the realistic scenario, the increase in clearings per decade is assumed to be 1.5 times, for the pessimistic scenario 3 times. The increased intensity of conversion is related to an increase in the cost of forest regeneration, where more than 60% of the cost is due to protective measures against wild animals. For the approaches and scenarios analysed, a decline in spruce can be expected in the range of 1–8% at the end of the next decade.
