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

Based on the synthesis of geomorphological principles and the preventative "zero-by-design" paradigm embedded in Australian forestry regulations, the reference value for active Gully Density in a production forestry system operating under best practice is 0 m/ha.

Metric Definition:

Gully Density is a measure of landscape stability, quantified as the total length of active gullies per unit area, typically expressed in metres per hectare (m/ha). Active gullies are defined by evidence of recent or ongoing erosion.

Benchmark Definition:

This benchmark represents the target for active gully density in production forestry systems under best-practice management in temperate grassy woodlands and plains, aiming for zero active gullies to prevent landscape degradation.

Justification:

The benchmark is justified by the regulatory framework and best-practice management aiming to prevent any active gully formation, as active gullies represent degradation and non-compliance with Codes of Practice.

Notes

The benchmark applies exclusively to active gullies; stabilized legacy gullies are not counted. Any presence of active gullies (>0 m/ha) is considered a direct transition to degradation.
