Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 2 benchmarks together — the OptimalRange form drives the primary score, while 1 guard(s) constrain the result.

Evidence & Context
The study found that the average ³b8crit²0 for arid ecosystems is 0.12 m³b3/m³b3, or 12% volumetric water content (VWC).
Critical soil moisture threshold (³b8crit²0) is the point at which key ecosystem processes transition from being limited by available energy to being limited by water availability.
The critical soil moisture threshold marks the lower limit of soil moisture where ecosystem functions begin to experience water stress in this arid inland floodplain biome under conservation management.
This threshold is the correct and most scientifically defensible lower boundary for high environmental health, as ecosystem productivity declines below this point.
