Some trees are best left alone I guess.
I agree with you there!! I had a situation a number of years ago where the Japanese Beetle (??) ransacked nearly all of the local pine trees. Early summer you could see some dead trees (brown) off to the side of my house and by the end of summer this line of brown dead trees had worked its way all across the yard and killed every pine near me. The problem I had with that is these were within range of hitting my home so they HAD to come down while they were still managable and not rotted out.
I'm the first to admit the ordeal I went through to get them out was one of the most nerve racking things I've ever done. I probably took 30/60 minutes per tree just looking at it, trying to ascertain where it would fall and then set up my machine to push towards that goal (pun somewhat intended

)
I was VERY relieved when it was over and I had the last one on the ground where I could now pull it to my burn pile.
Oh... I might add that I DID happen to ask a logger who was logging the farm if he wanted them. Although he said "sure" I went on to say that he could
have them as long as he didn't run roughshod over every other living tree that was near them as they had done on the farm with total disregard to other trees. I didn't care for any value for them OTHER than to simply respect the other things nearby. (with me knowing I'd have SOME casualties, just not my entire yard)
What I found interesting was he immediately said "nahhhhhhhh, no interest then" which helped underscore to me that they weren't really putting ANY effort into protecting the other trees on the farm like they said they would when they gave their sales pitch. Fortunately, it's not my farm so that wasn't my issue.
By the time I personally got done doing it, I ended up with a single young tree that bit the dust. I did not oblitherate my back yard (woods) like they did the rest of the area. No way they would have left as little damage in my area as I did.
