More White Pines and Spruce Dying
Another arborist tells me that the herbicide Imprelis, mentioned in a previous post as a possible culprit, would only affect the more manicured areas where herbicides are more likely to be used. Spruce and white pine have been dying in many unmanicured areas, and he sees climate shift as a likely cause. White pines and spruce were introduced to Princeton from their more natural range to the north, suggesting they'd be the first to show stress from increasing heat and drought.
Though all urban trees eventually have to be removed, typically at a cost of $1000 or more, one can speculate that the weather extremes associated with climate change are making those costs come due earlier than they would otherwise.
