More than 3000 random kauri, both healthy and unhealthy, will be tracked and monitored over years. "That's giving us far more of a greater understanding of what's happening across the whole kauri population," said council kauri dieback team manager Lisa Tolich. "So if you're just focusing on one population, i e those diseased trees, you're not really understanding how that disease is operating overall." This was the third kauri dieback survey rolled out by Auckland Council, with the first two focused on finding the kauri dieback-causing pathogen in the soil. The inclusion of healthy trees in the survey will provide better understanding of overall kauri health, says Lisa Tolich.
