I'm wondering what experiences others have had with really rotten pines trees. Today, I looked at 3 loblolly pines in the backyard of a previous client. All are just spars. One is 13" DBH about 45 ft tall. The top 30 feet fell to the ground within the last week. The other two are so close together, they've grown together at the bases (for about 2-1/2 ft.) One is 11", the other 14", maybe 65 ft tall. I probed them with a small screwdriver to see how decayed they are. I could stick the screwdriver into the 13" and 14" ones about an inch. The screwdriver went almost completely into the 11" spar, almost 4". And of course it's the one with the most lean towards the house. I'm thinking spider lift and bomb down small pieces is the safest removal tactic. (Which is not my gig.) There is an adjacent big yellow poplar, but the geometry doesn't look good trying to work the pines from it (too far away, not enough height advantage); plus I'd worry that a hard sneeze might cause big chunks of wood to fail unpredictably.
