Kauri Dieback Disease | February 2020
OSGF
An intensifying threat to living kauri trees in New Zealand is the emergence of “Kauri Dieback Disease,” which results in yellowing of leaves, premature loss of branches, thinning of tree crowns, lesions that bleed resin, and eventually tree death. The responsible pathogen is a species of Phytophthora, related to that responsible for the Irish Potato Famine of the late 1940s.
The New Zealand Department of Conservation and its partners take very seriously this threat to the remaining large kauri trees. Visitors are encouraged to clean and disinfect footwear and other equipment before and after entering kauri forest,
and to stay on the board walks and clearly specified tracks.
Some areas are also declared off-limits to visitors.
Precautions are also taken to avoid contact with, or damage to, the shallow feeding roots of kauri trees.
