eDNA Biodiversity Detection
Benchmark Value
Scoring Curve
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
Benchmark Value: 18 native vertebrate species.
Total number of native vertebrate species detected at the reference site.
This benchmark represents the total count of native vertebrate species detected by eDNA at the best available condition reference site in the arid inland floodplains and ephemeral river systems biome under aquaculture land use.
This value represents the highest observed native vertebrate species richness from a site (Darling River at Louth, Site 101) in an arid catchment during the GAWS Spring 2023 survey that also had zero detections of invasive fish, thus representing the 'best available condition' of the natural environment.
