Form: OptimalRange

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 4 benchmarks together — the OptimalRange form drives the primary score, while 3 guard(s) constrain the result.

Evidence & Context

This derived range is proposed as the reference benchmark for a production rainforest in a state of high environmental health immediately following a sustainable harvesting event.

Metric Definition:

Percentage of Tree Canopy Cover remaining post-harvest in production forestry systems within Australia's Tropical and Subtropical Rainforests biome.

Benchmark Definition:

A post-harvest Tree Canopy Cover range representing a sustainable management target balancing ecological health and timber production in tropical and subtropical rainforest production forestry.

Justification:

The benchmark is founded upon a robust, long-term empirical study linking basal area retention to ecological integrity, translated scientifically to canopy cover with moderate confidence due to modeling uncertainty.
