Gully Density — Benchmark Detail

Benchmark Value

0 m/ha

Direction: Lower is desirable ↓

Form: Point

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

Reference Value: ~0 m/ha (for active gullies resulting from land management)

Metric Definition:

Active gully density resulting from land management

Benchmark Definition:

This benchmark represents the target active gully density resulting from land management in the Australian arid inland floodplains and ephemeral river systems under production forestry. It reflects the goal of preventing active gullies caused by land management.

Justification:

The benchmark of ~0 m/ha for active, management-induced gullies is derived from first principles. It represents the required outcome of applying Australian sustainable forestry codes of practice, which are designed to prevent accelerated erosion, to a biome known to be exceptionally susceptible to catastrophic gully formation upon disturbance.

Notes

No direct empirical data exists for this specific land use/biome combination, as commercial forestry is not practiced in Australian arid floodplains. The benchmark represents the best available condition where gully initiation has been successfully prevented. No upper detrimental threshold — higher values are always worse. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
