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 optimal operational range can be defined as approximately 16 to 35 m²/ha.

Metric Definition:

Basal Area (BA) is 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).

Benchmark Definition:

Basal Area operational range balancing timber production and ecosystem health in production forestry.

Justification:

This range balances timber production, biodiversity conservation, and ecosystem health.
