BackgroundMaximising forest profitability is important from both economic and ecological perspectives. Managers of forest areas gain utility by optimising profits, and maximising the efficiency of a forest stand is also beneficial to the natural environment. This study presents a method to estimate and visualise forestry profitability based on variables defined in previous studies. The design space included economic and forest stand factors that can affect profitability. A contribution index analysis identified factors that significantly impact profitability, and these factors were then applied to data collected from a forest area in Japan. The effects of the two primary factors, discount rate and rotation period length, on a measure of profitability, the soil expectation value, were visualised in three-dimensional space.
