THE city council says it was an act of nature, but the Jetty Action Group isn't so sure and so is offering a reward for information leading to the identification of people responsible for what they allege is the poisoning of plants at the Jetty Foreshore.
Flyers have been issued offering a reward of $500 asking anyone with information to contact Crime Stoppers or the Jetty Action Group.
Coffs Harbour City Council had a small sample of leaves from the Jetty Foreshores tested at a laboratory and one page report details the levels of potassium and sodium as well as water soluble chloride and sulphate.
The report is now available on council's website but Jetty Action Group spokesperson Ashley Love questions the findings in the report.
It is council's position that the dead vegetation on the dunes is due to a raised salt-water table, but Mr Love says common sense doesn't suggest that argument is correct.
The pattern of dying vegetation raises more issues for concerned residents.
