Direction: Higher is desirable ↑

Form: LowerThreshold

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 4 benchmarks together — the OptimalRange form drives the primary score, while 3 guard(s) constrain the result.

Contributing Benchmarks

OptimalRange Primary LowerThreshold Guard UpperThreshold Guard LowerThreshold Guard

Evidence & Context

Lower Critical Threshold: <10%. Below this level, soil is inadequately protected from erosion and moisture loss, compromising fundamental ecosystem functions.

Metric Definition:

Lower critical threshold of litter cover percentage below which soil protection and ecosystem functions are compromised.

Benchmark Definition:

Critical lower threshold for litter cover to maintain soil protection and ecosystem function.

Justification:

Inferred from total ground cover guidelines and lowest EVC benchmark for grassy woodland systems.
