Source: Auckland Council Auckland Council surveys public land to monitor kauri dieback disease and for the first time will be extending its approach to include healthy trees in its studies. The latest kauri monitoring and surveillance programme has begun in the Waitākere Ranges with teams setting out to understand how the disease is impacting individual trees and the wider kauri population. Lisa Tolich, Auckland Council Team Manager- Kauri Dieback , says new remote sensing technology means that over the past few years, the council has been able to get a good estimate on how many individual kauri trees are in the ranges, and from that, draw a sample of trees to survey.
