Despite kauri dieback disease affecting many trees in Auckland and Northland forest, we still have some healthy kauri forests. Their disease-free status makes them even more precious.
One of these healthy forests is the Hunua Ranges, including Hunua, Waharau and Whakatiwai Regional Parks. The Hunua Ranges kauri have been confirmed as healthy after extensive aerial and ground surveys.
In the Hunua Ranges, cleaning stations for footwear and mountain bikes have been installed and large entrance signs remind visitors that they're entering a 'healthy kauri area' and should make sure they clean their shoes before heading into the forest.
"This disease is spread by soil movement so could be brought into Hunua on visitors' dirty shoes and equipment," says Ali Thompson, Senior Ranger Conservation for Southern Parks.
"Everyone working in or visiting kauri forest should make sure their footwear and equipment including bikes is clean of soil when they arrive and clean it again when they leave.
"It doesn't take much effort to do this and it is the only way we are going to protect the kauri in Hunua from this disease."
Visitors to parks and reserves should also always keep to the tracks.
