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 18 benchmarks together — the OptimalRange form drives the primary score, while 17 guard(s) constrain the result.

Evidence & Context
Lower Critical Threshold: This threshold is approached as basal area falls towards 0 m²/ha.
Basal area as a measure of tree canopy density and ecosystem structural integrity.
This benchmark represents the critical lower threshold of basal area below which woodland structure and ecological function are lost, indicating a degraded state.
The lower threshold is defined by a lack of natural regeneration and canopy cover below 10%, indicating a critically degraded state.
