Direction: Higher is desirable ↑

Form: Point

Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is Point, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.

Evidence & Context

"habitat clumps, which are undisturbed patches of about 30 m diameter, are now retained at a spacing of one clump every 5 ha"

Metric Definition:

Diameter of retained circular forest patches in harvested areas. (π * 15² = 706.8 m²)

Benchmark Definition:

This benchmark defines the diameter of retained undisturbed forest patches to maintain interior forest conditions in production forestry.

Justification:

Maintains interior forest conditions within the production matrix.
