Abstract

While forest cover decreased dramatically in the European Alps between the tenth and the nineteenth centuries, considerable reforestation occurred during the last 150 years and is likely to further increase in future. Depending on site conditions, this increased forest cover can protect from soil erosion and slope instability and may decrease flood hazard due to generally larger water storage capacity of forests compared to agricultural land. However, a decrease in sediment production may lead to channel narrowing and incision and thus increase flood risk. Furthermore, climate and land use change may have detrimental effects on soil stability, especially where droughts and heavy rain events will increase and/or at easily accessible areas with intensification of land use. Because of the high spatial variability of forest cover change and related hydrological effects, measures to optimize these effects are most promising on a local or regional level.
