The kauri is an iconic New Zealand tree that can live for thousands of years but there's a disease that is silently killing them and it's spread by the people who love our trees the most - bushwalkers.
Kauri dieback is caused by a microscopic organism that hitches a lift on their shoes and when it infects a tree, it rots the root system and then continues to travel upwards until it dies. You can tell a kauri is infected because it will start weeping gum, in an attempt to wall off the disease.
83% of bushwalkers walk past the cleaning stations in place to prevent the spread of the disease. How could we raise awareness of the disease in a unique way so that we may change this behaviour?
