Benchmark Value
Scoring Curve
The scoring engine could not generate a curve for this benchmark context. The primary form is OptimalRange, 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.
Contributing Benchmarks
Evidence & Context
The benchmark of 0 m/ha represents the 'best available condition' for Arid Karstic Woodlands under conservation.
Gully Density is the measure of the length of active gully networks per unit area of landscape.
This benchmark represents the natural, stable state of Arid Karstic Woodlands under conservation, characterized by no active gullies due to the region's geomorphology and hydrology.
The benchmark is justified by geomorphic principles, empirical radionuclide measurements showing negligible soil loss, and the absence of gully erosion as a threat in conservation management plans.
