Water Electrical Conductivity (EC)
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 11 benchmarks together — the OptimalRange form drives the primary score, while 10 guard(s) constrain the result.
Evidence & Context
The Tasmanian Government, applying these national principles, has published default trigger values that define a reference range for EC in Upland Rivers of 30–350 µS/cm.
Water Electrical Conductivity (EC) in upland rivers representing best available condition in production forestry catchments.
Default trigger values for water electrical conductivity in upland rivers as a proxy for best available condition in production forestry.
This range is based on national guidelines and extensive monitoring of minimally disturbed upland river catchments, representing the best available condition for sustainable production forestry.
