Form: MaximumOnly

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 7 benchmarks together — the OptimalRange form drives the primary score, while 6 guard(s) constrain the result.

Evidence & Context

An Upper Detrimental Threshold is identified at 50% bare ground, above which the risk of accelerated wind and water erosion becomes ecologically significant.

Metric Definition:

Upper detrimental threshold of bare ground percentage beyond which soil erosion risk becomes acute.

Benchmark Definition:

The critical upper limit of bare ground percentage to avoid accelerated soil erosion.

Justification:

Supported by scientific literature and field data indicating increased erosion risk above this threshold.
