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 19 benchmarks together — the OptimalRange form drives the primary score, while 18 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
A basal area below approximately 5 m²/ha is considered critically low.
Basal area below which the stand is too young or sparse to provide meaningful ecosystem services.
Critical lower threshold for basal area indicating insufficient ecological function.
Based on measurements of young shelterbelts (2-5 years old) with mean basal area of 4.1 m²/ha.
