The subject of the Rájec project (the Drahanská vysočina Upland) consists in the analysis of ecological impacts of intensive management in spruce monocultures growing on original sites of beech. Long-term studies were aimed at particular stand and environment stages after clear-felling regeneration and at the origin of a spruce monoculture of the 2nd generation. The establishment of the spruce monoculture can be considered to be most important. The highest attention was paid to the monoculture both from the aspect of carbon and nitrogen in particular components of the forest stand and their transport processes as well as from the aspect of water regime and biodiversity. The study was also aimed at the first stage of the clear-felled area development after felling a mature stand and also at functions of the herb vegetation, which reached its maximum production 4 to 7 years after felling. The paper objective was to assess spruce monocultures even outside their natural range from the aspect of changes in the forest environment as well as from the aspect of possible global changes of climate.
