They also created channels linking these wetlands. These channels contained weirs with large woven baskets made by women to cull mature eels. Professor Peter Kershaw, noted palynologist at Monash University, as cited by Bruce Pascoe in his best-selling work Dark Emu, found evidence of a sudden change in vegetation consistent with an artificial ponding system, and initial radiocarbon dating of the soil samples suggests the ponds were created up to 8,000 years ago.
