AUS-ASC-FOR-VEX General High confidence

Benchmark Value

7 trees/ha
Thresholds: Lower: 7, Upper: —
Direction: Higher is desirable ↑
Form: MinimumOnly

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

"the retention target is 7 to 12 well-spaced trees per hectare, which are left to provide a source of natural seedfall"

Metric Definition:

Minimum number of seed-bearing trees to be retained per hectare.

Benchmark Definition:

This benchmark defines the minimum number of well-spaced seed-bearing trees to retain per hectare to ensure natural seedfall.

Justification:

Necessary for the natural recovery of forest cover following harvest.

Notes

Lower Critical Threshold: 7 trees/ha. No upper detrimental threshold — higher values are always better up to natural saturation.
