Clear Cutting, Landslides and Soil Erosion


Scientists have studied the causes of landslides since the mid-1960s. Nearly every research study indicates that clear-cut timber harvesting increases the likelihood of landsliding on steep and unstable hillsides (from two to 31 times) and the erosion caused by landsliding (from two to 41 times), compared with uncut forests. These results appear to show general agreement that clear-cutting increases the incidence of landslides.
Limiting clear cutting to strip-clear cutting or even better "high-grading" selective cutting, can help prevent landslides and subsequent soil erosion.
