Short summary
Soil erosion by wind and water is a commonly recognized phenomenon on agricultural land. Erosion in forests is studied less and generally considered to be limited because of the soil protection by vegetation. However, trees, when toppled because of old age or wind, loosen a considerable amount of soil when their roots are pulled from the ground. In addition, the holes left in the ground act as collectors for water and concentrated runoff, causing significant soil loss on forested slopes.
