Gully Density
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 8 benchmarks together — the OptimalRange form drives the primary score, while 7 guard(s) constrain the result.

Evidence & Context
The only scientifically defensible and logically consistent benchmark for active gully density in a best-practice sustainable or regenerative cropping system is 0 m/ha.
Gully Density, expressed as the total length of active gully channels per unit of land area (e.g., metres per hectare, m/ha), quantifies the spatial extent and severity of active gully erosion.
This benchmark represents the ideal state of zero active gully erosion in agricultural crop production on Australia's Tropical & Subtropical Maritime Islands, indicating a stable and non-degrading landscape.
Derived from first principles of soil science and supported by literature on erosion control and sustainable agriculture, this benchmark reflects the goal of maintaining landscape stability and ecological health.
