eDNA Biodiversity Detection

AUS-TDG-AGR-DNA General Moderate confidence

Benchmark Value

60 count
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

The proposed reference value is >60 detected vertebrate species, based on a multi-taxa eDNA metabarcoding study of farm dams and waterways in West Gippsland, Victoria.

Metric Definition:

Number of detected vertebrate species from water eDNA metabarcoding

Benchmark Definition:

This benchmark represents a minimum threshold of vertebrate biodiversity detected by eDNA metabarcoding in agricultural waterways of temperate dry woodlands and native grasslands, indicating a healthy biodiversity state.

Justification:

This benchmark is a proxy derived from the best available, albeit not perfectly matched, real-world dataset from agricultural landscapes in Victoria's temperate biome. Confidence is Moderate due to the source being a conference abstract and land use not being strictly defined as 'regenerative cropping'.

Notes

The value represents a demonstrated achievable state of high biodiversity in a working agricultural landscape. All richness values are underestimates, constrained by the current incompleteness of Australia's DNA reference libraries. No upper detrimental threshold — higher values are always better up to natural saturation. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
