Evidence & Context

The optimal functional range for litter cover is proposed to be 70-95%.

Metric Definition:

Optimal functional range of litter cover percentage balancing soil health benefits and fire/regeneration risks.

Benchmark Definition:

Range of litter cover percentage that maximizes soil protection and moisture retention while managing fire fuel hazard and regeneration needs in the Arid Inland Floodplains biome under production forestry.

Justification:

This range is based on balancing the benefits of litter cover with the risks of excessive fuel loads and regeneration failure, supported by observed data and ecological understanding.
