In northern Australia, detecting aquatic species can be difficult, labour-intensive and expensive, due to factors such as remote locations, expansive geographic areas, limited and variable site access, and hazards such as crocodiles. A new Hub research project is therefore developing eDNA technology and trialling field methods to help make surveying as simple as collecting a water sample. Plants and animals shed cells containing their DNA into the rivers and creeks where they live. This is called ‘environmental DNA,’ or eDNA. A water sample from a river contains this eDNA and so gives information about which plants and animals are present in the area. Such information will improve our knowledge of several priority conservation species and pest species in northern Australian and inform development planning processes, impact assessments and management decisions. For more information, see the start-up factsheet or contact Project Leader Professor Damien Burrows.

Our Northern Hub Newsletter highlights what's going on in our research projects across northern Australia. It includes latest findings, what's coming up and what this all means for sustainable development and land and water management in the region.
The North Australia News Roundup is an informal monthly collation of news relevant to developing northern Australia. It aims to facilitate cross-sector and cross-region knowledge sharing, and more informed conversations and decisions about the future of the region!
