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 maximum size of clearfall, seed tree or shelterwood 1 coupes is 40 ha net harvested area.

Metric Definition:

Maximum allowable net harvested area of a single coupe using even-aged silvicultural systems in State forests.

Benchmark Definition:

Maximum coupe size to restrict contiguous intensive canopy removal in Alpine Ash production zone.

Justification:

The cited source explicitly identifies the value as a regulatory maximum coupe size.
