Scoring Curve

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

Evidence & Context

"Whereas pre-disturbance stem densities calculated from remnants of previous populations suggest densities of between 24 and 240 stems per hectare according to site, current stem densities arising from flushes of regeneration this century are calculated as between 700 and 5550 stems per hectare."

Metric Definition:

Overstorey stem density of mature, unmanaged, and long-undisturbed (pre-disturbance) subalpine woodlands dominated by Eucalyptus pauciflora.

Benchmark Definition:

Reference-condition range for overstorey stem density in mature, structurally stable, long-undisturbed subalpine woodland ecosystems.

Justification:

The cited source explicitly identifies the value in a reference-site context for the Australian Alpine and Subalpine Complex conservation woodlands.
