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
While the detrimental threshold is defined as any value > 0 m/ha, the data from rural landscapes (Table 1) can be used to establish a qualitative scale of degradation severity.
Density of active gullies per hectare at which environmental degradation begins.
This benchmark represents the upper detrimental threshold for gully density in urban and developed areas of arid mountain ranges and uplands in Australia. Any presence of active gullies (greater than 0 m/ha) indicates environmental degradation and a failure of best-practice management.
Any measurable density of active gullies is detrimental to environmental health and indicates a failure of best-practice management. This threshold is based on the functional analysis of gully erosion impacts and best-practice management goals.
