eDNA Biodiversity Detection
Benchmark Value
Scoring Curve
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.
Contributing Benchmarks
Evidence & Context
An eDNA result showing only a handful of native species (e.g., <5), none of which are threatened, alongside a strong and consistent signal from high-impact invasive species like European carp, would signify a system in poor health.
Lower critical threshold for native species richness indicating ecological function loss.
This benchmark defines the minimum native species richness threshold below which ecological function is considered compromised in aquatic eDNA surveys in conservation areas of the Australian Temperate Grassy Woodlands & Plains biome.
Defined by the consistent absence of expected sensitive native species and/or dominance of invasive species, reflecting a compromised ecological state.
