Abstract
The article presents selected results of the project of the Czech National Agency for Agricultural Research, “Differentiation of intensities and management practices in relation to forest biodiversity and economic sustainability of forestry” executed at the Department of Forest Economy and Forestry Management, Faculty of Forestry and Wood Sciences, Czech University of Agriculture in Prague. The results included the quantification of forest rotation periods derived from total mean increment, total mean value increment, and annual gross profit of forest production. Significant differences between the rotation period currently recommended and the rotation period relevant to economic optimum (maximum) were observed. The better the forest site (site quality class), the bigger is the difference
