Change in forest species composition and its projections into the economy of forest owners.

Increasing the proportion of broadleaved trees in stands during regeneration raises questions about how these trees will be reflected in the economics of forest owners and whether these owners can influence certain economic aspects during stand management. In this respect, the paper focuses mainly on the revenue side of forestry and, crucially, analyses the selling prices of assortments of tree species groups as offered in public tenders of state forests under the outsourcing business model. The price level of spruce is used as a benchmark for comparisons in the analyses. It is clear that the cultivation of species-diverse forests entails an increase in the representation of a higher number of tree species and, presumably, increased stand stability. However, a concomitant consequence may be an increase in costs and a reduction in returns for forest owners. Here, the revenue from timber sales can be improved by appropriate adjustment of the species composition through educational interventions. All this is in the context of the economic viability of forestry, as declared in a number of strategic and forest policy documents, which essentially depends on the timber production function of forestry and the subsequent processing of timber.
