Gully Density

AUS-ASC-LVG-GUL General High confidence

Benchmark Value

0.5 km/km²
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

Healthy alpine/subalpine catchments should maintain a gully density of <0.5.

Metric Definition:

Gully density expressed as length of gullies per unit area (km/km2).

Benchmark Definition:

Reference-condition ceiling for gully density in healthy alpine and subalpine catchments.

Justification:

The cited source explicitly identifies the value in a reference-site context for Australian alpine and subalpine rangelands.
