Importance: great.

Soil functions affected:
Biomass production, environmental functions (transformation, filtration), hydrological function, reduction of carbon sequestration, functions for preventing offsite effects (sediment supply during floods, silting up of dams).

Diagnostic criteria:
Those corresponding to each type of erosive process.
Prevention and control:
Study of the rainfall regime and local landform. Envisage a system of forest exploitation that takes into account the risk of erosion in the area.
