(2014): Increasing forest disturbances in Europe and their impact on carbon storage
NAT CLIM CHANGE. 2014; 4(9): 806-810. FullText FullText_BOKU

Disturbances from wind, bark beetles and wildfires have increased in Europexxxs forests throughout the twentieth century(1). Climatic changes were identified as a key driver behind this increase(2), yet how the expected continuation of climate change will affect Europexxxs forest disturbance regime remains unresolved. Increasing disturbances could strongly impact the forest carbon budget(3,4), and are suggested to contribute to the recently observed carbon sink saturation in Europexxxs forests(5). Here we show that forest disturbance damage in Europe has continued to increase in the first decade of the twenty-first century. On the basis of an ensemble of climate change scenarios we find that damage from wind, bark beetles and forest fires is likely to increase further in coming decades, and estimate the rate of increase to be +0.91 x 10(6) m(3) of timber per year until 2030. We show that this intensification can offset the effect of management strategies aiming to increase the forest carbon sink, and calculate the disturbance-related reduction of the carbon storage potential in Europexxxs forests to be 503.4 Tg C in 2021-2030. Our results highlight the considerable carbon cycle feedbacks of changing disturbance regimes, and underline that future forest policy and management will require a stronger focus on disturbance risk and resilience.
