Benchmark Value

0.75 ratio

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 CompositeFramework, 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

Upper Detrimental Threshold: Native Richness Ratio (NRR) < 0.75.

Metric Definition:

Native Richness Ratio (NRR) below 0.75 indicating a system compromised by invasive species.

Benchmark Definition:

This benchmark defines the upper detrimental threshold where the native richness ratio falls below 0.75, indicating the ecosystem is compromised by invasive species dominance.

Justification:

Indicates that invasive species make up more than a quarter of the detected vertebrate community, signaling loss of native character and ecological resilience.
