April will see a survey in the McKenzie river by the Wimmera Catchment Management Authority. Among others they hope to find the two baby platypuses first recorded last April, the first time in a decade that juveniles had been detected. The survey will also provide valuable information about the impact of environmental water releases in the river.
The researchers will also be trialling a new technique called eDNA which tries to pick up traces of DNA in the water (from hairs, faeces etc) . This can indicate the presence of platypus without actually trapping them or even seeing them. At this stage it can’t pick out individuals, or how recent the activity is, but it can be a basis for where it is worth taking a closer look.
