Western red cedars in South Langley, BC are dying, with browning starting at the tops during summer and progressing downward until the trees are completely dead.
This happened about 250 m from the shore of the Fraser River in a creek at Colony Farms.
In the last few years, I have observed a significant die-off of Western red cedar in several high traffic and peripheral areas of Pacific Spirit Regional Park (PSRP). The majority of the cedar trees I saw were noticeably consumed by browning, small, and young, with most likely more shallow root systems. This is consistent with vegetative stress to which young trees have not developed resilience, but older trees may be less impacted
While there is no risk to human health, the species of moth can decimate forests
