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
Therefore, the benchmark is most appropriately expressed as a range that reflects this management cycle. The lower end of the range is the post-harvest minimum of 23 m²/ha. The upper end represents a well-stocked, mature stand ready for its next selective harvest. An upper value of 35 m²/ha is proposed, as this level allows for substantial standing volume and growth while remaining below the detrimental threshold where the stand begins to lose its open woodland character.
Basal Area (BA) is defined as the total cross-sectional area of all tree stems in a given stand, measured at 1.3 meters above the ground (DBH), expressed as square meters per hectare (m²/ha).
Basal Area is the total cross-sectional area of all tree stems at breast height per hectare, expressed as a range reflecting sustainable management in production forestry.
This range is derived from a comprehensive sustainable forestry framework that integrates production and conservation objectives.
