I hadn't heard, so thank you for the update. It was just a matter of time before it spread from Boulder.

This is going to be devastating. I have one ash I'll treat, will just cut down the others as they become infected. I've spent the last few years interplanting different species around the ash so the yard won't be barren when the ash succumb. But it takes decades to develop a canopy. I'll miss their shade.

Sad but expected news. I don't have any Ash trees in my yard but I grew up with one in R.I.; wonder if it is still alive. It was magnificent when I lived there, but that was 40+ years ago. There is an estimate that over 50 MILLION ash trees have been infected and/or killed by the borer thus far in the USA - it's in Canada as well - and it was only introduced (from China?? Something else we can thank them for?? From Asia, anyway....) in the 1990's.

The ash tree will be sorely missed when it disappears from our gardens and forests. I hope you are able to save yours, Barb. :-(
