Sean the tree was banded for lack of better technology--dozens still seen in Europe--, then replaced by worse technology. In countries with a heritage of chastity belts, they thought it necessary to hold a tree together in that way with compression all around.
I'm primarily an arborist. I...
Sean to be stationary I think those were eyebolts; could not get the specs. Way too big a footprint imo; cabling X in branches would have done it, crown not large. Then the tree was mulched to death...
"All he said was not to loose or too tight." which complies with ANSI A300. Jon, please...
http://www.historictreecare.com/761/ shows what to do with damaged bark from tying.
Stand-offs do way too much damage, as seen in this blog post. Steel cabling is a better solution than standoffs or bracing, or at least it would have been for the Kvill Oak...
Man that is a big foreign object to drive through a tree. ANSI and ISA are way too quick to prescribe those imo.
They have their place, but only in big trees with big cracks. There, they are lifesavers!
Thank goodness we finally see the spruce. I might spec 1 cable (3/8" EHS) installed just above the 'kiss' (about 8' up), secured with terminal fasteners. $65.00 in materials, 1/2 hour labor. Or, depending on the crown, maybe nothing. Prescribing all those rods is a ton of overkill.
"I...
Many holes in Jon's logic, but that one is huge!
Zero maintenance is not a reasonable expectation after ANY service. Jon don't you use a disclaimer? I'm wondering where all this liabilophobia comes from.
How's the chipper safety campaign going?
Looping above laterals might work, if you like BranchSaver.
Installing a 5/16" steel cable with terminal fasteners requires one small 3/8" hole. Just sayin.
