Didymo for KC.org

A single drop of water can spread this terrible pest, so Canyoners must be extremely vigilant to CHECK, CLEAN and DRY their gear in accordance with the direction on the biosecurity website.

Research demonstrates how important it is to use the correct concentration of cleaning agent.

Didymo is not the only pest that threatens our waterways. The Biosecurity website has more information. Also, the National Institute of Water and Atmospheric Research (NIWA) has an information page about the many unwanted plant species.

By awareness of the risks and application of CHECK, CLEAN, DRY we can keep our canyons pristine for all to enjoy.

PLEASE ensure you do your part, it only takes a moments carelessness to alter a watercourse forever. There is no known way to remove didymo completely once a water way is infected.
