What is eDNA?

eDNA, or environmental DNA, is a cutting-edge technology used for wildlife detection and monitoring. It is a non-invasive sampling technique that is gaining popularity due to its effectiveness and cost-efficiency.

All animals release DNA into their surroundings, such as through mucus, faeces, urine, gametes, and skin cells. Scientists can now extract and analyse DNA from water, air, or soil samples to trace the presence of various species. For instance, a water sample can capture evidence of a platypus being in a creek within the past 24-48 hours.
