“…However, growths models have not yet been fully integrated into the forest management practice (Porté andBartelink 2002, Machar et al 2016) and are rarely used to assess the forest management strategies in conservation areas (Sodtke et al 2004). The advantage of growth simulation models lies in reasonably accurate predictions of the future character of forest stands under variable growth conditions and types of forest management (Kolström 1998). We believe that the combination of a growth simulation model with the analysis of historical forest development could be more widely used, especially to assess management plans for conservation areas that consist of forest ecosystems (Idle andBines 2005, Machar 2010).…”

Nature Conservation 22: 51-78. https://doi.org/10.3897/natureconservation.22.12902 AbstractEuropean beech-dominated forests are crucial for maintaining biodiversity in forested mountain landscapes of the European temperate zone. This paper presents the results of research and assessment of management strategy for mountain beech-dominated forests in the Jeseníky Mountains (Czech Republic). Our approach is based on combining research on historical development of the forest ecosystem, assessment of its current state, and predictions of future dynamics using a forest growth simulation model. Using such a method makes it possible to understand the current state of the mountain beech-dominated forest ecosystem and predict its future development as a response to specific management strategies. The application of this method is therefore appropriate for assessing the suitability of selected management strategies in mountain protected areas. Our results show that a non-intervention management for mountain beech forest in the next 80 years complies with the Natura 2000 requirement to maintain the existing character of the forest habitat. Thus, the current management plan for the beech-dominated forests in the Jeseníky Mountains does not require significant corrections in the context of its conservation targets (i.e. maintaining biodiversity and current character of the forest ecosystem dominated by beech). The results of this study suggest that combining the knowledge on historical development with forest growth simulation can be used as a suitable support tool to assess management strategies for forest habitats in protected areas.

“…The study was conducted by using an ecosystem model (Sima) (Kellomäki et al, 1992Kolström, 1998), which simulates forest growth and development according to the implemented forest management and a given climate scenario. In addition, an emission calculation tool was developed and it was used together with Sima for assessing the CO2 emissions of the management operations in the production chain, such as harvesting and transportation.…”

Alam, A. 2010. Effects of forest management and climate change on energy biomass and timber production with implications for carbon stocks and net CO 2 exchange in boreal forest ecosystems. Dissertationes Forestales 117. 30 p. Available at: http://www.metla.fi/dissertationes/df117.htm ABSTRACTThe aim of this work was to investigate the effects of forest management and climate change on energy biomass (wood) and timber production with implications for carbon stocks and net CO 2 exchange in boreal forest ecosystems in Finland. First, the impacts of thinning on growth, timber production and carbon stocks under the current and changing climate were analysed by employing an ecosystem model for the whole of Finland over a 90-year period (Article I). Concurrently, the potential of energy biomass production with implications for timber production and carbon stocks under varying thinning and climate scenarios was studied (Article II). Thereafter, a life cycle assessment (LCA) tool for estimating net CO 2 exchange of forest production was developed (Article III), and it was applied in interaction with ecosystem model based simulations to study the impacts of different management regimes (initial stand density and thinning regimes) on energy biomass production and related CO 2 emissions at a stand level with a rotation length of 80 years (Articles III & IV).The results showed that the climate change increased the production potential of energy biomass and timber, and carbon sequestration and stocks over the whole of Finland, but, in a relative sense more in northern than southern Finland (Articles I & II). Decreasing basal area based thinning thresholds compared to the currently recommended ones, increased the harvesting of the annual average amount of timber compared to the annual average growth of stem wood, and reduced carbon stocks in the forest ecosystems (Article I). On the other hand, the use of increased basal area thinning thresholds concurrently increased energy biomass and timber production, and carbon stocks in the forest ecosystem regardless of climate applied (Article II). The development of the LCA tool made it also possible to estimate the net carbon exchange of the forest production (Article III). Based on the use of the LCA tool with the ecosystem model simulations, it was found that the impacts of management related emissions on net carbon exchange were small compared to the total ecosystem fluxes. It was also found that the increase in initial stand density compared to the conventional practice of 2000 seedlings ha -1 , not only increased the energy biomass production at energy biomass thinning, but also reduced management related CO 2 emissions of energy biomass production (Article IV).To conclude, the applied management substantially affects the net atmospheric impacts of production potential of forest ecosystems. The combined use of ecosystem model simulations and the LCA tool will together provide new insights for the analysis of ecologically sustainable energy biomass and timber production systems ...
