Climate change and forests' sensitivity to storm and spruce bark beetle damage
Fredrik Lagergren and Anna Maria Jönsson report on their ongoing research on storm and spruce bark beetle damage on spruce. They conclude that the sensitivity of spruce forests to wind and spruce bark beetles may increase with climate change and that the main causes are that the trees grow taller, less ground frost and that the spruce bark beetles will more often develop a second generation. How these risks evolve depends also on forest management. Shorter rotation length could be an effective measure to reduce the risk.The article (pdf, 110 kB)
