Soil Moisture

AUS-AMR-LVG-SMO General Moderate confidence

Benchmark Value

10 %

Thresholds: Lower: 10, Upper: —

Direction: Higher is desirable ↑

Form: LowerThreshold

Scoring Curve

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

Evidence & Context

Lower Critical Threshold: The Permanent Wilting Point (PWP). Crossing this threshold risks irreversible loss of perennial vegetation and triggers accelerated soil erosion. It corresponds to a VWC of approximately <10% for sandy loams.

Metric Definition:

Permanent Wilting Point (PWP) - soil moisture level below which plants cannot extract water and ecosystem degradation accelerates.

Benchmark Definition:

Soil moisture level below which plants cannot extract water and ecosystem degradation accelerates.

Justification:

Crossing this threshold risks irreversible loss of perennial vegetation and triggers accelerated soil erosion.
