[CANUFNET] Western redcedar decline in the Pacific Northwest

[Naomi Zurcher]

Good afternoon Julian:

I was wondering if you know if this has spread to the Thuja plicata population on Haida Gwaii? I no longer have any contacts there and I have not been able to determine the known footprint of the problem through what’s available online.

I am assuming this problem is of Climate Change origin rather than any exotic pathogen.

Thanks, in advance

The decline has been obvious in the Lower Mainland for well over a decade. It is very pronounced on Vancouver Island along with the death of Grand fir and Douglas-fir trees. The intent is to show the extent of the problem as a first step, and then work on options for replanting perhaps with different species. This first step hopes to show the extent of the problem.
