Scoring Curve

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

Evidence & Context

There is no simple upper detrimental threshold for litter cover; rather, high litter cover (>70-80%) requires contextual assessment.

Metric Definition:

"Litter cover" refers specifically to the percentage of the ground surface covered by non-living, detached plant material.

Benchmark Definition:

This range highlights that very high litter cover requires contextual assessment, as it may indicate either a healthy mature system or a degraded state with elevated fire risk.

Justification:

The upper boundary is context-dependent and not a fixed detrimental threshold.

Notes

No upper detrimental threshold — higher values are always better up to natural saturation. High cover can be a sign of degradation if from invasive annuals. Fire risk increases continuously with mass. Management should focus on composition and structure, not just percentage.
