Winds of Change – Management of even-aged pedunculate oak forests in increasingly windier climate
Current scenarios of climate change predict increase of the annual mean temperature, changes in the precipitation regime, and increase in the frequency and intensity of extreme weather events, e.g. forest fires and wind storms. While the effects of changing temperature and precipitation on forest ecosystems are less evident, negative impact of the strong wind is clearly evident from storms like Vivian (1990) or Lothar (1999). The aim of our contribution is to analyze the data on wind damage inflicted by two recent wind storms that occurred in one of the world's largest forest complexes of pedunculate oak – "Spačva" forest basin. The vulnerability of pedunculate oak stands is assessed with regard to stand age and stand structure. The "Spačva" forest basin covers ca. 43 000 ha in Croatia and ca. 18 000 ha in Serbia. The current silvicultural system applied to these forests is even-aged management with shelterwood regeneration in three cuts. During the last decade, the Croatian part of the forest basin was hit twice by severe wind storms, in 1998 and 2008, with the amount of wind-thrown wood of 170 000 m3 and 107 000 m3, respectively. The results of the analysis indicate increase in the risk of wind damage with increasing stand age. The highest intensity of wind damage was recorded in the stands where the seed cut was performed and only small number of large pedunculate oak trees were left for the final felling. In these stands, wind has uprooted or broken over 70% of the trees. Based on these results, it is evident that the current management system of shelterwood regeneration on large areas should be reconsidered in the view of higher probability of occurrence of severe wind storms in the future.
