eDNA Biodiversity Detection

AUS-TSR-LVG-DNA General Low confidence

Benchmark Value

144 count
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

Proxy data from a large-scale survey of the managed Murray-Darling Basin detected 144 vertebrate species.

Metric Definition:

Number of vertebrate species detected via eDNA metabarcoding

Benchmark Definition:

This benchmark represents the number of vertebrate species detected using eDNA metabarcoding as a proxy reference for biodiversity in managed agricultural landscapes, given the absence of direct data for tropical rainforest grazing areas.

Justification:

A direct benchmark for best-practice grazing in Australian tropical rainforests is not available in scientific literature. This value is a proxy from a large-scale study in a different (temperate/arid) but heavily agricultural Australian landscape.
