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

"retaining 30% cover of native vegetation in a landscape could be used as a conservation surrogate if there is evidence that a substantial number of species will not persist below this level (threshold)."

Metric Definition:

Landscape-scale target for native vegetation cover to act as an effective multi-taxa conservation surrogate.

Benchmark Definition:

Landscape-scale target for native vegetation cover to act as an effective multi-taxa conservation surrogate.

Justification:

Synthesized empirical target from literature on landscape-level ecological thresholds.

Notes

Based on a standard 100 km2 (10,000 ha) study landscape, 30% cover is equivalent to 3,000 ha.
