Evidence & Context

Benchmark for Best Available Condition: 100% ground cover in non-paved, non-turf green spaces.

Metric Definition:

Litter Cover (%) representing the best available condition of nature for Urban & Developed Land Use within Australia's Tropical Monsoonal Savannas.

Benchmark Definition:

This benchmark represents the best available condition of litter cover in urban and developed areas of Australia's Tropical Monsoonal Savannas, aiming for complete ground cover in non-paved, non-turf green spaces to maximize ecological functions.

Justification:

The 100% benchmark is a management target derived from the stated goals of best-practice urban landscape management in Australia's tropical savannas.

Notes

No upper detrimental threshold — higher values are always better up to natural saturation. This benchmark refers to coverage by a combination of living groundcover, natural litter, and applied organic mulch in non-paved, non-turf areas.
