Great Article on Invasive Shot Hole Borer

The Invasive Shot Hole Borer (formerly called the Polyphagous Shot Hole Borer) is still a threat to native and introduced trees here in California, and although in some cases it seems to be mellowing out just a little bit, it still has the capability of getting worse -especially during the curent severe drought.
