“…On spruce, the frequency of I. typographus attacks increases with tree diameter, while P. chalcographus L. shows the opposite trend (G€ othlin et al, 2000;Schroeder et al, 1999). High spruce stumps are much less frequently attacked by these two species than broken trees and downed tops (G€ othlin et al, 2000;Luitjes, 1976;Schroeder and Eidmann, 1993), and sunny logs seem to be more suitable than sunny slash. Moreover, the brood survival of Dendroctonus rufipennis Kirby is poorer in logging residue than in windfelled trees (Dyer and Taylor, 1971 in Safranyik and Linton, 1999).…”

“…Most studies have found that infestations are more extensive during the second year (e.g. Inouye, 1963;Schroeder and Eidmann, 1993). In Sweden, G€ othlin et al (2000) showed that P. chalcographus attack rates doubled in the second summer, and that even broken trees were affected, although they lack life-supporting root contact and are possibly desiccated by sun.…”

“…The most common form of snow damage is stem breakage or bending when the soil is frozen, but trees can also be uprooted if the soil is not frozen (Petty and Worrell 1981;Lundqvist 1992a, b, 1994;Solantie 1994;Nykänen et al 1997). Consequential damages by insects or fungal attacks are also common in trees suffering from snow damage (Persson 1972;Rottmann 1985;Schroeder and Eidmann 1993;.…”

Impacts of climate change on the risk of snow-induced forest damage in Finland

This work studied the temporal and spatial variability of the risk of snowinduced forest damage in Finland under current and changing climatic conditions until the end of this century. The study was based on a snow accumulation model in which cumulative precipitation, air temperature and wind speed were used as input variables. The risk was analyzed in terms of the number of days per year when the accumulated amount of snow exceeded 20 kg m −2 . Based on the risk, the forest area and mean carbon stock of seedling, young thinning and advanced thinning stands at risk were calculated. Furthermore, the number of 5-day periods, when the accumulated amount of snow exceeded a risk limit, was calculated for the current and changing climatic conditions in order to study the frequency of damaging snowfalls. Compared to the baseline period 1961-1990, the risk of snow-induced forest damage and the amount of damaging snowfalls were predicted to decrease from the first 30-year period (1991-2020) onwards. Over the whole country, the mean annual number of risk days decreased by 11%, 23% and 56% in the first, second and third 30-year period, respectively, compared to the baseline period. In the most hazardous areas in north-western and north-eastern Finland, the number of risk days decreased from the baseline period of over 30 days to about 8 days per year at the end of the century. Correspondingly, the shares of the forest area at risk were 1.9%, 2.0% and 1.0% in the first, second and third 30-year period, respectively. The highest mean annual carbon stocks of young stands at risk were found in central, north-eastern and north-western Finland in the first and second 30-year period, varying between 0.6 and 1.2 Mg C ha −1 year −1 , meaning at highest 3% of the mean carbon stock (Mg C stem wood ha −1 ) of those areas. This study showed that although the risk of snowinduced forest damage was mainly affected by changes in critical weather events, the development of growing stock under the changing climatic conditions also had an effect on the risk assessment. However, timely management of forest stands in the areas with a high risk of snow-induced damage contributes to the trees' increased resistance to the damage.

“…Wind damage may lead to departures from the forest management plan as damage in a forest area may force the forest owner to perform unscheduled and costly thinnings as well as clear-cuttings. These activities are performed to salvage-harvest damaged timber and prevent insect attacks on broken and uprooted trees spreading to healthy trees (Schroeder and Eidmann 1993).…”

This study deals with the problem of including the risk of wind damage in longterm forestry management. A model based on Graph-Based Markov Decision Processes (GMDP) is suggested for development of silvicultural management policies. The model can both take stochastic wind events into account and be applied to forest estates containing a large number of stands. The model is demonstrated for a forest estate in southern Sweden. Treatment of the stands according to the management policy specified by the GMDP model increased the expected net present value (NPV) of the whole forest only slightly, less than 2%, under different wind-risk assumptions. Most of the stands were managed in the same manner as when the risk of wind damage was not considered. For the stands that were treated differently, however, the expected NPV increased by 3% to 8%.
