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

Given that the presence of any active gully represents a state of instability, the only scientifically defensible numerical benchmark for the density of active gullies in a best-practice, high-health industrial landscape is zero.

Metric Definition:

Gully Density measured as the length of active gullies per hectare.

Benchmark Definition:

This benchmark represents the target density of active gullies in a well-managed industrial landscape within tropical and subtropical rainforests, indicating a stable, non-degrading landform with no active erosion.

Justification:

This value is derived from the primary objective of best-practice industrial land rehabilitation in Australia, which is to create a safe, stable, non-polluting, and erosion-free final landform.

Notes

An "active" gully is defined by evidence of recent erosion (e.g., headcut retreat, scour, bank collapse) as per the NESP Gully Classification Scheme. The presence of any active gully (>0 m/ha) indicates active land degradation and failure to meet best-practice stability goals. No upper detrimental threshold — higher values are always better up to natural saturation. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
