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