Gully Density

AUS-TSW-LVG-GUL General Moderate 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 OptimalRange, 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 Lower Critical Threshold for maintaining health is 0 m/ha; any value >0 indicates the system is already in a degraded state.

Metric Definition:

Lower Critical Threshold for Gully Density below which the landscape maintains health and stability.

Benchmark Definition:

This benchmark defines the minimum gully density threshold in temperate semi-arid shrublands and open woodlands under livestock grazing, below which the landscape is considered healthy and stable.

Justification:

Cross-validated by land condition frameworks and ecological principles indicating any gully presence signals degradation.

Notes

No upper detrimental threshold — higher values indicate degradation. This threshold represents the geomorphic initiation point of gullies; values above zero indicate degradation.
