Basal Area
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 12 benchmarks together — the OptimalRange form drives the primary score, while 11 guard(s) constrain the result.
Evidence & Context
The value of 19.0 m²/ha, derived from the maximum stocking index (P95 BA) of the Corymbia citriodora forest type in the Lewis et al. (2021) study, is proposed as the primary reference benchmark.
Basal area is defined as the total cross-sectional area of all tree stems in a stand, measured at breast height (1.3 meters above the ground), expressed as area per unit of land area, typically square meters per hectare (m²/ha).
Basal area is the total cross-sectional area of all tree stems in a stand at breast height, expressed as m²/ha.
This value represents the 95th percentile of observed basal area (P95 BA), indicating a fully stocked stand approaching its self-thinning limit, serving as a high-functioning upper-range benchmark for sustainably managed production forest.
