Pinus taeda, loblolly pine leans over garage/entrance to house and electric line. pic #1, Split is ~2m long with large pitch tubes from southern pine beetle activity at bottom of split, on both sides. Compare the difference between this copious reaction by the tree to the insects, and the lack of pitch in that weak infested pine Ljack showed us a few weeks ago (this one's for you C, but get to bed--growing boys need their rest!).
Elderly client has had many trees taken down over the years due to storms (and risk assessment by others) and prefers to keep this one if it can be brought to a reasonable level of risk. I already did the work but will stop here to get opinions. The Burl thread is getting some educational responses that have sharpened my thinking on "collars" and are fun to read, so lurkers please jump in. It's safe here; you have nothing to lose but a little time, and the knowledge of others to gain!
(pic is large but will be resized below.) My rent is paid and my "crew" has enough work. How should I manage this tree?
