Benchmark Value
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 18 benchmarks together — the OptimalRange form drives the primary score, while 17 guard(s) constrain the result.

Evidence & Context
Lower Critical Threshold: <10%. Below this level, soil is inadequately protected from erosion and moisture loss, compromising fundamental ecosystem functions, especially during drought or post-disturbance.
Litter cover is a crucial attribute of ecosystem health, influencing soil stability, moisture retention, nutrient cycling, and the structure of ground-layer habitat.
The minimum litter cover required to protect soil from erosion and moisture loss.
Below this level, soil is inadequately protected from erosion and moisture loss, compromising fundamental ecosystem functions, especially during drought or post-disturbance. This level aligns with the lowest benchmark identified for a grassy woodland system (10% for Plains Grassy Woodland in the Goldfields bioregion).
