Gully Density

AUS-AKW-IND-GUL General High confidence

Benchmark Value

0 m/ha
Direction: Lower is desirable ↓
Form: MaximumOnly

Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is Point, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.

Evidence & Context

The most relevant threshold concept is the upper detrimental threshold. For this indicator and biome, the detrimental threshold is crossed at the point of initiation of any active gully erosion. Functionally, this threshold is > 0 m/ha of active gullies.

Metric Definition:

Upper detrimental threshold for Gully Density indicating the onset of active gully erosion.

Benchmark Definition:

This benchmark defines the maximum acceptable gully density in the Arid Karstic Woodlands & Shrublands under Industrial & Infrastructure Use. Any presence of active gullies (greater than 0 m/ha) is considered detrimental, indicating the onset of active erosion.

Justification:

The formation of even a single gully represents a fundamental shift in the geomorphic state and indicates failure of the engineered system to prevent erosion.

Notes

Any presence of active gullying on a rehabilitated landform is detrimental to the goal of creating a stable, self-sustaining ecosystem. Gullies act as erosion hotspots and create positive feedback loops of degradation. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
