I found your website on Google.

I travelled through Wyoming and Montana this summer and the large number of apparently sick (i.e. turning brown) trees struck me. In Montana, near Pocatello, approx half or 50% of the pine trees were not doing well. Near Flathead Lake MT, I made a few close-up pictures of what was going on. It seems that insects (moths or beetles?) are eating the young sprouts, and this will kill the new branches and -eventually- the whole tree.

Can you tell me what’s going on? I’ve seen Ponderosa Pine and Lodgepole Pine trees suffering from beetles, but this seems to be different.

Best regards,
