Climate change impacts on growth and carbon balance of forests in Central Europe

et al. 2011

We analysed climate change impacts on the growth and natural mortality of forest tree species and forest carbon (C) balance along an elevation gradient extending from the Pannonian lowland to the West Carpathian Mountains (Central Europe). Norway spruce Picea abies, European beech Fagus sylvatica, and oak Quercus sp. were investigated for 2 future time periods: 2021-2050 and 2071-2100. The period 1961-1990 was used as reference. Forest growth simulations were based on the SIBYLA tree growth simulator (an empirical model), and C cycle-related simulations were performed using BIOME-BGC (a process-based biogeochemical model). Growth simulations indicated that climate change will substantially affect the growth of spruce and beech, but not of oak, in Central Europe. Growth of spruce and beech in their upper distribution ranges was projected to improve, while drought-induced production decline was projected at the species' receding edges. Beech was the only species projected to decline critically at lower elevations. C cycle simulations performed for the zone of ecological optima of the 3 tree species indicated that these forests are likely to remain net carbon dioxide sinks in the future, although the magnitude of their sequestration capacity will differ. Increasing nitrogen deposition and atmospheric carbon dioxide concentration were projected to greatly affect the forest C cycle. A multi-model assessment based on SIBYLA and BIOME-BGC simulations performed for the zone of ecological optima suggested that oak production will either remain the same as in the reference period or will increase. Future production of beech seems uncertain and might decline, while spruce production is likely to increase. The results also confirmed the value of multi-model approaches for assessing future forest development under climate change.KEY WORDS: Norway spruce · European beech · Oak · Forest carbon cycle · Tree production · Tree mortality · BIOME-BGC model · SIBYLA tree growth simulator Resale or republication not permitted without written consent of the publisher

Structural parameters of Scots pine stands (129-191 years) on their natural sites (270-600 m a.s.l.) are described on 6 permanent research plots (PRP; 3 in managed stands using near-natural silvicultural practices and 3 in stands without active forest management for 3 decades at least) in areas of western, central and eastern Bohemia and in the Polish part of the Krkonoše Mts. In the framework of the study structural and growth parameters, horizontal and vertical structure and biodiversity were evaluated on the plots. A comparison of the plots, and of managed and unmanaged plots showed a relatively high variability in different parameters. Nevertheless, the results document that managed stands, compared to forest stands without management, mostly have significantly higher standing volumes (1.5 times in total and 1.7 times in pine), which is caused by more extreme sites. An opposite trend was found out in dead wood volume, which is distinctly higher in unmanaged stands. Differences in the other parameters are not so pronounced, probably because small-scale management is used and because a relatively short time since the stands were left to spontaneous development has elapsed (30-52 years).

“…In order to estimate the projected value of provenance selection at rotation age (120 years) we modelled the development of volume value and economic production using a forest bio-dynamic simulator (SIBYLA) (Fabrika 2005;Fabrika, Ďurský 2005). …”

Productivity of individual European larch provenances was evaluated on the basis of height and diameter growth and volume production at the age of 40 years. This work was focused on identifying differences among European larch provenances using a growth simulation model (SIBYLA). Based on the growth simulations, all selected provenances had greater mean height, stem diameter and stem volume at the age of 120 years than the control seed source. Provenance 49 (Krnov-Loučky, Jeseníky, CZ) had the greatest height growth and volume, but it ranked the fourth in diameter. Provenances 16 (Cavalese, Italy) and 71a (Jaroměřice-Chroustov, Vysočina, CZ) ranked the highest in stem diameter and volume growth. With respect to a different tree number per hectare these characteristics are different when expressed as total per-hectare volume production. Despite that fact, the control material is inferior also in this category. In addition to production, timber assortment and economic balance of the same provenances at the age of 120 years were evaluated.
