Evidence & Context

Upper Detrimental Threshold: >5.0 m/ha. This threshold is derived from the model identifying the top 3% most-gullied areas and corresponds to landscapes with highly active, unstable gullies requiring major engineering intervention for stabilization.

Metric Definition:

Gully Density, the length of active gullies per unit area

Benchmark Definition:

Gully Density is the length of active gullies per unit area, indicating landscape stability and erosion status. This benchmark marks the upper limit beyond which landscapes are highly unstable and require major engineering intervention.

Justification:

The upper detrimental threshold is supported by the model identifying the top 3% most-gullied areas and aligns with government management frameworks for unstable gullies.
