“…Rotation ages were reduced to 120 yr also in higher elevation stands, and two thinnings were conducted in all stands. The AM1 strategy thus reflects the frequent recommendation to shorten rotation periods and increase thinning frequency in order to (Seidl et al 2011, Loisel 2014). In addition to these two strategies developed with stakeholders, two bracketing management strategies were designed (HIST and AM2), representing contrasting alternative management options.…”

The ability of forests to continuously provide ecosystem services (ES) is threatened by rapid changes in climate and disturbance regimes. Consequently, these changes present a considerable challenge for forest managers. Management of forests often focuses on maximizing the level of ES provisioning over extended time frames (i.e., rotation periods of more than 100 yr). However, temporal stability is also crucial for many ES, for example, in the context of a steady provisioning of resources to the industry, or the protection of human infrastructure against natural hazards. How temporal stability and the level of ES provisioning are related is of increasing interest, particularly since changing climate and disturbance regimes amplify temporal variability in forest ecosystems. In this simulation study, we investigated whether forest management can simultaneously achieve high levels and temporal stability of ES provisioning. Specifically, we quantified (1) trade-offs between ES stability and level of ES provisioning, and (2) the effect of tree species diversity on ES stability. Simulating a wide range of future climate scenarios and management strategies, we found a negative relationship between temporal stability and level of ES provisioning for timber production, carbon cycling, and site protection in a landscape in the Austrian Alps. Tree species diversity had a predominantly positive effect on ES stability. We conclude that attempts to maximize the level of ES provisioning may increase its temporal variability, and thus threaten the continuity of ES supply. Consequently, considerations of stability need to be more explicitly included in forest management planning under increasingly variable future conditions.

“…This study employed a solution space to visualise the effects of various factors on forest profitability, measured through SEV. When the results are compared with previous studies (Loisel 2014;Price 2011), our study provides additional information, such as the stability of forest profitability, which is shown by the density of contour lines in the solution spaces (Fig. 2).…”

Background: Maximising 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. Methods: The site used in this study, located by Morotsuka village in the Miyazaki Prefecture, Japan. Variables previously found to have significant effects on forestry profitability were used to define a design space of variables for calculating and displaying profitability, after which data from the cited study were used to estimate the variables' SEV contribution indices. The effects of the important factors for forestry profitability were then analysed and visualised. Dimensions of the design space were constructed from previously published forestry inventory data and consisted of two stand condition factors, three site condition factors, one economic condition factor and one silvicultural planning factor. This study used previously published inventory data regarding stand age, site index and tree species. Additionally, the forestry profit simulator was used to estimate the optimal rotation period in terms of soil expectation value. The relationships between SEV and these significant factors were then graphically visualised. The significant factors identified as described above were used to estimate SEV-based profitability distributions, based on the inventory data used to construct the design space and optimal rotation periods, for the studied forest. Results: Changes in rotation period affected forestry profitability. However, the effect depended on stand, site and economic conditions. In scenarios characterised by relatively low site productivity index and harvesting area, which results in low profitability, rotation period changes did not have a strong effect on profitability. On the other hand, it was vital to select the optimal rotation period for high profitability areas as even a small deviation had a significant impact on profitability. Furthermore, it was shown that by synchronising the harvesting times of small, adjacent stands, the overall profitability increased through reductions in forest management costs.

“…In Reed (1984), the tree damage is not modelled and thinnings are not considered. In the case of a storm, its occurrence depends on a probability density function but the intensity of damage is closely linked with the stand characteristics such as height and diameter (Loisel, 2014).…”
