eDNA Biodiversity Detection

AUS-AMR-AGR-DNA General Low confidence

Benchmark Value

18 species/plot

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

eDNA Biodiversity Detection (Macroinvertebrates): 18 Families Detected per waterbody.

Metric Definition:

Number of unique macroinvertebrate families identified per waterbody using eDNA metabarcoding

Benchmark Definition:

This benchmark represents the average number of macroinvertebrate families detected per waterbody using eDNA metabarcoding in agricultural crop production areas of the Arid Mountain Ranges & Uplands biome.

Justification:

This value is the average macroinvertebrate family richness from a subset of the same farm dams. It is a more direct indicator of in-situ waterbody health.
