Scoring Curve

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

Evidence & Context

The data indicates that shrub cover is a dominant component of the understorey in these montane wet sclerophyll forests: Native Ground Cover - Shrubs (GCS) 10% to 40%.

Metric Definition:

Native Ground Cover - Shrubs (GCS) percentage cover in the ground layer of Alpine Ash - Mountain Gum moist shrubby tall open forest

Benchmark Definition:

Percentage cover of native shrubs in the ground layer as a structural benchmark for subalpine forest understorey.

Justification:

Derived from data-driven benchmarks comparing current site conditions against a reference state for the specific Plant Community Type (PCT 1191).
