Gully Density

AUS-TSR-FOR-GUL General Moderate confidence

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 of new or actively expanding gullies attributable to forestry operations.

Metric Definition:

Gully Density is the measurement of new or actively expanding gullies attributable to forestry operations within a given area.

Benchmark Definition:

This benchmark represents the target operational state for new or actively expanding gullies caused by forestry activities in tropical and subtropical rainforest production forestry areas, where the ideal condition is zero new gully formation.

Justification:

The benchmark is based on preventative principles in Australian forestry codes designed to eliminate gully erosion, recognizing that a well-managed site should have zero new or expanding gullies. Although a quantitative field benchmark is not available, this target reflects best practice operational goals.
