In a stack column diagram, the share of all incidental uses in the total felling is shown in percent from 1991 to 2012. Accidental uses caused by wind/storms and other causes add up to 100 percent in the bars. The proportions vary greatly between the years. The share of wind/storm was highest in 1991 with 82 percent, in 2000 with 93 percent, in 2007 with 90 percent and in 2008 and 2009 with about 72 percent each. A trend has not been discernible so far. An additional line represents the share of incidental uses in the total logging in percent. It shows a course with strong fluctuations and is without trend. Particularly high values were recorded in 1991 with 67 percent, in 2000 with 55 percent and in 2007 with 45 percent. The values in the other years fluctuate between 10 and 40, but mostly between 10 and 20 percent.
