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, indicating complete ground cover in non-paved, non-turf green spaces.

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. Sources like the "Creating Habitat for Darwin Gardens" guide and revegetation manuals implicitly aim for complete ground coverage in planted areas to maximize ecological functions like soil protection, moisture retention, weed suppression, and habitat creation. This benchmark refers to coverage by a combination of living groundcover, natural litter, and applied organic mulch in non-paved, non-turf areas.
