- The study describes a new method of assessing the average age of the forest range with significant share of stands in the regeneration class. In proposed method, average age of stands in regeneration layer is calculated as a mean age of tree layer as well as layer of upgrowth, recruitment and saplings weighed by these layers fraction. Example of calculation of average age was performed for 7 ranges located in Kotlina Kłodzka (SW Poland) with total area of 48 653 ha. Average age of stands calculated by proposed method vary from 62 to 73 years and is lower in comparison to average age calculating according to current regulations from 5 to 14 years. Proposed method of calculation the average age of stands in shelter wood cutting system takes into account composed structure of stands in regeneration period by using age and share of all trees generation in stand.
