The article discusses the threats to radiata pine health presented by Ensis in a forest health workshop held in Rotorua, New Zealand. These include the nectria flute canker, a fungus disease confined to the lower half of the South Island; Cyclaneusma needle cast, most prevalent in the central North Island and on the East Cape; physiological needle blight, a disorder usually affecting radiata pine trees 12 years or older in Northland, East Cape/Poverty Bay and Westland. Other threats include dothistroma, armillaria root disease and exotic pests and diseases such as the western gall rust from North America and the pine pitch canker from Chile. The Forest Owners Association is proposing long term radiata forest condition monitoring, a process that can be facilitated by remote sensing.
