Evidence & Context

"at least 70% groundcover is required to prevent excessive run-off and erosion."

Metric Definition:

Percentage of the soil surface covered by plants, litter, or other materials

Benchmark Definition:

This benchmark defines the minimum groundcover percentage required to prevent excessive run-off and erosion in the Alpine and Subalpine Complex biome under production forestry land use.

Justification:

70% is the critical threshold for soil stability and water infiltration in the region.

Notes

No upper detrimental threshold — higher values are always better up to natural saturation. Litter is the primary component of groundcover in forested areas.
