- There is a lack of an acceptable and practical method for calculating the optimal moment at which a forest stand is considered ready for felling. The aim of the research was to: (1) develop a concept for the calculation of the rotation age for forest stands based on economic criteria and (2) develop a methodology for obtaining and processing empirical data necessary for such calculation. It is assumed that stands are felled at the age affecting the age structure (area of age classes) of a forest in such a way that the difference between revenues from the sale of timber harvested in inter−mediate cuts and final cuts and the costs of timber harvest, silvicultural management, forest protection and administration is the largest. The developed method of calculating the rotation age was tested on the example of three Scots pine forests under the clear−cutting system representing typical forest habitats. The collected empirical material consisted of (1) own measurement data used to determine the value of the growing stock, and (2) data from the State Forests Information System used to determine the management costs, timber prices and the volume of timber harvested from intermediate cuts. These data helped to calculate the relationship between the income from a forest (including: revenues from the final and intermediate cuts, costs of forest management as well as timber harvesting and extraction) and the rotation age. The highest net income was when the rotation age was 108−125 years. The more fertile habitat, the shorter was the rotation age. The proposed methodology can be treated as a useful tool for the calculation of rotation age related to forest management in Poland. The dependence of income from a forest on the rotation age can be used to calculate losses that may arise when other than an optimal rotation age is applied.
