Evidence & Context

Therefore, a benchmark of ²6590% is established.

Metric Definition:

Litter Cover (%) - the percentage of ground surface covered by organic litter such as fallen leaves, twigs, and bark in tropical rainforest production forestry.

Benchmark Definition:

This benchmark represents the minimum litter cover percentage considered achievable under sustainable production forestry management in Australian tropical rainforests, reflecting a management philosophy prioritizing maximum retention and low-impact harvesting.

Justification:

Derived from the North Queensland selective logging model aiming to leave 40-60% of coupes undisturbed combined with Reduced-Impact Logging principles minimizing bare ground in disturbed areas.

Notes

This benchmark is an inferred target based on historical best-practice principles and analogous ecosystem data, reflecting a management philosophy of maximum retention and low-impact harvesting. No upper detrimental threshold — higher values are always better up to natural saturation.
