Evidence & Context

Reference Value: Presence/Absence of ~150 vertebrate and invertebrate taxa detected across a catchment-scale sampling program.

Metric Definition:

Presence or absence of vertebrate and invertebrate taxa detected by eDNA metabarcoding across a catchment-scale sampling program.

Benchmark Definition:

A proxy benchmark representing the best available condition of eDNA biodiversity detection in production forestry within the Arid Mountain Ranges & Uplands biome.

Justification:

This benchmark is a proxy derived from the best available large-scale eDNA dataset from analogous Australian arid and semi-arid riverine systems, specifically the Murray-Darling Basin's Great Australian Wildlife Search program.

Notes

No direct studies exist for this specific biome and land use. The value represents the total species pool detected across hundreds of sites in the Murray-Darling Basin, reflecting a healthy, biodiverse catchment at a regional scale. Confidence is not 'High' due to the proxy nature of the data. There is no evidence for an upper detrimental threshold for native biodiversity. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
