Scoring Curve

This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.

Evidence & Context

The Department of Primary Industries and Regional Development (DPIRD) in Western Australia recommends retaining "at least 50% groundcover" to minimize wind erosion risk and formally classifies ground cover of less than 30% as constituting a "high hazard rating".

Metric Definition:

Litter Cover (%)

Benchmark Definition:

This benchmark represents the minimum litter cover recommended to minimize wind erosion risk in Arid Karstic Woodlands & Shrublands agricultural cropping systems, with risk increasing significantly below this threshold.

Justification:

This indicates that while risk begins to increase significantly below 50%, it becomes acute below 30%.
