Environmental DNA (eDNA) is a non-invasive sampling technique that detects genetic material from a target species secreted into the surrounding environment (e.g. water).

During 2020 the Upper Campaspe Landcare Network conducted the Platypus Project aimed to address the lack of contemporary knowledge about platypus and blackfish populations by investigating the current distribution of platypus and blackfish throughout the upper Campaspe area of the North Central CMA region using eDNA.

Senior ecologist and platypus expert Dr Josh Griffiths from EnviroDNA led the project and provided the technical knowledge and advice to Citizen Scientists participating in this Project.  Here he tells us all about it in a fascinating 14 minute video perfect for older students.
