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.
Factors like reduced summer precipitation, extreme heat events, and ponderosa pine's superior drought resilience highlight the need to adapt reforestation practices to species more suited to changing environmental conditions.
"In our country Afghanistan I have observed that the level of water is decreasing day by day."
Blue sap was found on a spruce tree.
There are at least 10 or more what appears to be otherwise healthy trees that have just fallen over.

The Hemlock Looper Moth outbreak is said to last between 3-4 years and now coincides with an outbreak of Phantom Hemlock Looper which saw its last outbreak more than a decade ago.
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
Unusually large cone crops may be the result of favorable variations in weather across several years.
I noticed sections of trees that had fallen over and or had their tops broken off. I'm wondering if it was a micro storm or a disease that affected the trees.
