eDNA Results Spring 2023

Odonata Foundation and the Murray–Darling Basin Authority (MDBA) are pleased to announce the public release of the findings from the Great Australian Wildlife Search's spring 2023 environmental DNA (eDNA) sampling season in the Murray–Darling Basin.

We partnered with EnviroDNA, utilising cutting-edge eDNA technology to reveal fascinating insights into the region's biodiversity, across 324 sites, highlighting the critical importance of conservation efforts and integration of emerging scientific technology.

For a neat summary of findings, download the Great Australian Wildlife Search - Biodiversity Findings Report Spring 2023 (9-pages).

Notes on using the map and interpreting results

  • When you click on a site (blue circle), the number to the right of each species is the sequence count. This is an indication of how many times a DNA sequence was counted. It is not an indication of how many individuals were detected, although sequence counts do give you a fair indication of what the most dominant things are in that area. The rule of thumb is that the data is mainly used to detect presence or absence, rather than number of individuals.

  • Sometimes the map times out, a quick click of the refresh button often does the trick.

  • Zoom in with your mouse or touch screen to locate your location on the map.

  • The dropdown boxes allow you to filter via classification, threat status and species.

  • Click on the blue circle to access the site number and results.
