Direction: Higher is desirable ↑

Form: MinimumOnly

Scoring Curve

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

Evidence & Context

A lower critical threshold is identified at approximately 30% cover, below which core ecosystem functions are significantly compromised.

Metric Definition:

Litter cover, the proportion of the ground surface covered by dead plant material.

Benchmark Definition:

A litter cover below 30% is a critical threshold where essential ecosystem functions are significantly impaired in the Arid Inland Floodplains & Ephemeral River Systems biome.

Justification:

This threshold aligns with the RARC framework scoring and broader rangeland and soil science principles indicating minimum ground cover for erosion control.
