Evidence & Context

A visual analysis of this chart reveals that for sites classified as being in 'good' condition, the average cover of litter is approximately 60%.22

Metric Definition:

Litter Cover (%)

Benchmark Definition:

This benchmark represents the average litter cover percentage observed at sites in good condition within the Arid Mountain Ranges & Uplands biome under production forestry land use.

Justification:

The reference value of ~60% is derived from the average litter cover observed in 'good' condition Victorian Semi-arid Woodlands, the most relevant analogue for the specified context. Confidence is 'Moderate' as it is from a high-quality analogue study rather than direct measurement in the target biome/land use.

Notes

No upper detrimental threshold — higher values are always better up to natural saturation. The observed ~60% litter cover reflects a balanced ecosystem budget where production and retention maintain this crucial layer.
