The Clarence River Guardians in collaboration with Southern Cross University, is calling for participants in a major citizen science survey of the Clarence River.
The comprehensive Baseline Sediment Survey will collect samples from key locations throughout the Clarence River catchment.
Community members are invited to participate as citizen scientists over the weekend of 18-19 October in the collection of more than 100 samples. Training will be provided.
Analysed for heavy metals and chemical elements
The samples will be analysed for heavy metals and more than 50 chemical elements by experts from Southern Cross University, in laboratories on the Northern Rivers campus.
The sediment survey will provide a health check of the Clarence River and its catchments – an essential foundation for understanding future changes and guiding environmental care.
Southern Cross University hydrogeochemist, Professor Scott Johnston, says science can guide us to make better decisions about how we manage our rivers. ‘This comprehensive data will establish a baseline for monitoring.
Community is at the heart of this project
‘The community is at the heart of this project and the sediment collection would not be possible without their help.’
Yaegl Elder Aunty Elizabeth emphasised the important role of the river. ‘Our ancient river connects people and communities to land and to each other,’ she said.
President of the Lions Club of Clarence Tracy Patemen said these kinds of partnerships between communities and scientific institutions are becoming increasingly important.
‘We are so grateful to be in partnership with Southern Cross University and for the community momentum that’s building behind the project.’
Community working hand-in-hand
This project is a powerful example of science and community working hand-in-hand for a healthier Clarence River.
Participant citizen scientists need to be able to reach collection sites unassisted. The central hubs for the survey will be Grafton and Tabulam. Teams of at least two adults (25+) will be trained via short online videos and provided with sampling kits, maps, and instructions.
The Guardians are a community-led initiative in partnership with Southern Cross University and the Lions Club of Clarence (Environmental).
