Scoring Curve

This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.

Evidence & Context

Therefore, the benchmark for Litter Cover (%) representing the best available condition in a high-functioning, sustainably managed urban ecosystem is 100%.

Metric Definition:

Litter Cover (%) representing the best available condition in a high-functioning, sustainably managed urban ecosystem.

Benchmark Definition:

The benchmark represents 100% surface coverage of pervious areas, achieved via a 75mm layer of organic mulch as specified in best-practice Water Sensitive Urban Design (WSUD) technical standards for bioretention systems.

Justification:

This engineered ecosystem standard is the most relevant proxy for 'best available condition' in a managed urban landscape.
