These same people who were so upset by this aren’t horrified by the protected species birds killed by the wind turbines & solar arrays? Or human abortions?

If they were pines, the primary means of a tree acquiring bark beetles are the scent of the terpines emitted from freshly cut or trimmed local trees...

Yes. Wounds on the trees themselves also attract the bugs, because of the excess sap emitted. These trees had lots of wound areas.

I didn't realize that was the attractant until I researched it a bit. I think the tree is healthy enough to treat, so I'm going to try and do so. The tree was certainly weak from lack of water, as it has brightened up considerably since we've begun watering it. The property we're in has sat vacant for months, and the prior residents didn't appear to take very good care of the trees (or any other vegetation) on the property.

Don’t they get bark beetles, too, if it is dry and they are not in top condition? I think so — drought/ infestation.

Yes, but the sap is what will bring them from a long ways off.
