Concern about the polyphagous shot hole borer is spreading up the west coast, with this article from the Seattle Times. The author does a great job of laying out the known history of PSHB research, and concisely stating why everyone should be concerned:
The consequences of a wide-ranging infestation could be enormous. Common city trees, such as American sweet gum and maple, would become public branch-dropping hazards. Native trees such as the California sycamore and the coast live oak have started to succumb, creating a fire risk in the form of dead, dry tinder. Avocados and other crops could face huge financial losses.
