These Western redcedar have died off over the last ten years, due to drought (according to my neighbour). Indeed they stand in a fairly sub-mesic area, on a moisture-shedding slope, near a hilltop crest. Western redcedar standing in such relatively dry conditions will be the first to show signs of stress during periods of drought, and could make good indicators for monitoring climate change.
Thuja plicata, commonly called Western or Pacific redcedar,giant or western arborvitae,giant cedar, or shinglewood, is a species of Thuja, an evergreen coniferous tree in the cypress family Cupressaceae native to western North America. Despite its common names, it does not belong with the true cedars within the genus Cedrus. It is the Provincial tree of British Columbia, and has extensive applications for the indigenous First Nations of the Pacific Northwest.
