Evidence & Context

Persistent cover approaching 100% is detrimental as it (a) creates a 'High' to 'Very High' fire fuel hazard, and (b) inhibits essential seedling regeneration which requires bare soil.

Metric Definition:

Upper detrimental threshold of litter cover percentage beyond which fire risk and regeneration inhibition occur.

Benchmark Definition:

Threshold of litter cover percentage above which ecosystem function is harmed due to fire hazard and regeneration failure in the Arid Inland Floodplains biome under production forestry.

Justification:

Based on fire management protocols and ecological observations of seedling establishment requirements.
