OptimalRange Primary LowerThreshold Guard UpperThreshold Guard LowerThreshold Guard

Evidence & Context

Upper Detrimental Threshold: >60%. Above this level, excessive litter accumulation becomes detrimental.

Metric Definition:

Upper detrimental threshold of litter cover percentage above which ecosystem function and biodiversity are harmed.

Benchmark Definition:

Critical upper threshold for litter cover beyond which negative ecological impacts occur.

Justification:

Based on literature showing suppression of native species regeneration, soil acidification, and increased fire risk.
