Abstract [en]

We simulated how possible changes in wind and ground-frost climate and state of the forest due to changes in the future climate may affect the probability of exceeding critical wind speeds expected to cause wind damage within one northern and one southern study area in Sweden, respectively. The topography of the study areas was relatively gentle and the forests were dominated by Norway spruce (Picea abies (L.) Karst.) and Scots pine (Pinus sylvestris L.). Using estimated changes in the net primary production (NPP) due to climate change and assuming a relative change in the site productivity equal to a relative change in NPP, we simulated possible future states of the forest under gradual adjustment of the site index in response to climate change using the model The Forest Time Machine. Global climate change scenarios based on two emission scenarios and one general circulation model were downscaled to the regional level. The modified WINDA model was used to calculate the sensitivity of the forest to wind and the probability of wind damage for individual forest stands for the periods 2011–2041 and 2071–2100 and for a control period 1961–1990. This was done while taking into account effects on stability of the forest from expected changes in the occurrence of ground frost. Increasing sensitivity of the forest to wind was indicated for both study areas when adhering to recommended management rules of today. Adding also a changed wind climate further increased the probability of wind damage. Calculated probabilities of wind damage were generally higher in the southern study area than in the northern one and were explained by differences in wind climate and the state of the forests, for example with respect to tree species composition. The indicated increase in sensitivity of the forest to wind under the current management regime, and possibly increasing windiness, motivate further analysis of the effects of different management options on the probability of wind damage and what modifications of Swedish forest management are possibly warranted.

Abstract [en]

We estimated how the possible changes in wind climate and state of the forest due to climate change may affect the probability of exceeding critical wind speeds expected to cause wind damage within a forest management unit located in Southern Sweden. The topography of the management unit was relatively gentle and the forests were dominated by Norway spruce (Picea abies (L.) Karst.). We incorporated a model relating the site index (SI) to the site productivity into the forest projection model FTM. Using estimated changes in the net primary production (NPP) due to climate change and assuming a relative change in NPP equal to a relative change in the site productivity, we simulated possible future states of the forest under gradual adjustment of SI in response to climate change. We estimated changes in NPP by combining the boreal-adapted BIOMASS model with four regional climate change scenarios calculated using the RCAO model for the period 2071–2100 and two control period scenarios for the period 1961–1990. The modified WINDA model was used to calculate the probability of wind damage for individual forest stands in simulated future states of the forest. The climate change scenarios used represent non-extreme projections on a 100-year time scale in terms of global mean warming. A 15–40% increase in NPP was estimated to result from climate change until the period 2071–2100. Increasing sensitivity of the forest to wind was indicated when the management rules of today were applied. A greater proportion of the calculated change in probability of wind damage was due to changes in wind climate than to changes in the sensitivity of the forest to wind. While regional climate scenarios based on the HadAM3H general circulation model (GCM) indicated no change (SRES A2 emission scenario) or a slightly reduced (SRES B2 emission scenario) probability of wind damage, scenarios based on the ECHAM4/OPYC3 GCM indicated increased probability of wind damage. The assessment should, however, be reviewed as the simulation of forest growth under climate change as well as climate change scenarios are refined.

Abstract [en]

We (1) estimated how the possible changes in wind climate due to climatic change may affect the probability of exceeding critical wind speeds (CWS) expected to cause significant wind damage within a forest management unit located in southern Sweden, (2) analysed how the probability of exceeding an approximate CWS as observed in the management unit would change in different regions in Sweden if expecting a similar kind of forested area to occur in different geographical locations. The topography of the management unit was relatively gentle and the forests were dominated by Norway spruce (Picea abies (L.) Karst.). Seven regions across Sweden were selected for comparison of possible future probability of damaging wind speed. The model-system WINDA was modified and used for calculations of the probability of wind damage together with regionally downscaled climate change scenario (CCS) data. In total, two climate scenarios downscaled using the RCAO model for the control period 1961–1990 and four for the period 2071–2100 were used. The CCSs represent fairly central projections on a 100-year time scale in terms of global mean warming. Although there is ambiguity between different CCSs, the results indicated that the present pattern of more windy conditions in southern than in northern Sweden will remain. For most sites the probability of exceeding the CWS from westerly to south-westerly directions was indicated to remain comparatively high and the probability of damaging wind from south-westerly to south-easterly directions was indicated to increase in many places. For southernmost Sweden increasing probability of exceeding the CWS from the north-westerly to south-easterly wind directions were indicated for all but one CCS. The results were discussed with respect to spatial planning in forestry under a changing wind climate.

Abstract [sv]

Att klimatet kan komma att förändras påverkar svenskt skogsbruk. Skogen har i sig en direkt inverkan på klimatet samtidigt som skogsbruket kan behöva anpassas till de nya förhållandena. Ett osäkert klimat sätter brukandet av skogen i ett nytt läge som vi inte har någon tidigare erfarenhet av. Scenarier för framtida klimatutveckling är behäftade med stor osäkerhet och de förväntade effekterna på skogen blir således ännu mer osäkra. Trots detta kan man ändå förutsäga några sannolika huvuddrag i effekterna på den svenska skogen vid ett framtida ändrat klimat. En ökad potential för biomassaproduktion kan förväntas, liksom ökade möjligheter att använda nya arter i skogsbruket. Samtidigt ökar sannolikt risken för vissa typer av skador.

Att väga eventuella fördelar i form av ökad produktion och ökade möjligheter i trädslagsval mot ökade risker för skador är viktigt för att ge samhället ett helhetsperspektiv och för att en större grupp ska ha möjlighet att ta till sig frågan. Det är också viktigt att i största möjliga mån kvantifiera eller ge ramarna i ekonomiska termer för hur det förändrade klimatet kan tänkas påverka skogsbruket. Vidare kan det vara styrande för prioritering av fortsatta forskningsarbeten och riskbedömning och för att prioritera åtgärder. Därför har vi försökt utifrån befintlig kunskap idag, konstruera en Tabell över den ekonomiska betydelsen och forskningsbarheten för olika risk/ämnesområden (se Tabell 17 sidan 39). De kanske största effekterna av ett förändrat klimat på ekonomin inom skogsbruket skulle vara om vi lyckas utnyttja den ökade produktionspotentialen. Det förutsätter att vi kan bemästra de negativa effekterna i första hand av en ökad risk för vindfällning, skadeangrepp från insekter och svampar. Mot bakgrund av skogsbrukets stora betydelse som naturresurs och industriell bas, så finner vi att det är viktigt att vi står rustade inför en framtid med såväl ökade hot som nya möjligheter.

I denna skrift försöker vi beskriva och analysera tänkbara effekter av ett förändrat klimat på skogen och bedömt deras implikationer för produktionsskogsbruket. Andra aspekter än produktionsaspekter på skogsbruket har inte behandlats. Analysen sker i fyra steg. Vi inleder med att, så långt nuvarande kunskapsläge tillåter, kvantifiera effekterna på den skogliga primärproduktionen – tillväxten i skogen. I ett andra steg omsätts dessa effekter till effekter på produktionsekonomin i ett bestånd. Därefter analyseras tänkbara effekter på risken för stormfällning i skogen. I ett sista steg breddas diskussionen till en något mera spekulativ bild av tänkbara effekter på skogsbrukets ekonomi.
