Gully Density

AUS-TGP-CON-GUL General Moderate confidence

Benchmark Value

5 m/ha
Direction: Lower is desirable ↓
Form: UpperThreshold

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

A gully density of > 5.0 m/ha (> 0.5 km/km2) places a site among the top 3% of the most severely gully-eroded landscapes in the MDB. A conservation area exhibiting a gully density in this range is in a critically degraded state. This value serves as a scientifically defensible Upper Detrimental Threshold.

Metric Definition:

Gully Density

Benchmark Definition:

The maximum acceptable gully density for conservation areas in the Temperate Grassy Woodlands & Plains biome, above which a site is considered critically degraded.

Justification:

Based on the statistical distribution of gully densities across the MDB, where > 5.0 m/ha represents the top 3% of most severely eroded landscapes.
