Evidence & Context

An optimal range for total ground cover (a mosaic of mulch and living plants) in managed urban green spaces is approximately 50-90%.

Metric Definition:

Total ground cover (%) combining mulch and living plants in managed urban green spaces.

Benchmark Definition:

The functional optimal range of total ground cover for ecological health in urban arid floodplain green spaces, balancing soil protection and plant health.

Justification:

Synthesized from lower and upper thresholds to balance soil protection and avoid negative impacts.
