hole in tree

[Myron711]

I have a 50' tall Norway Maple in the corner of my yard. It has hole in it at the intersection of its 3 major limbs. The hole sits about 18' high. The diameter of the hole is about 4" wide by 12" deep. Either birds or squirrels have used it I was told to cover up the hole with a piece of tin. But then i read to let it breath as closing it up will cause for more decay.

Any thoughts or suggestions are appreciated...

Cut it down!

You may want to post this in a different forum like commercial tree care.

The first thing to consider is whether or not there is a target: children playing, house, powerlines (if you really care) where the structural weakness is a concern. If the answer is yes, then consider further. Weight reduction of the crown will reduce stress on the decayed portion. No, do not cover, for the reason stated.

I can't remember and am not about to look up the standards, but if you have something in the range of >30% of the diameter with sound wood then its within reason that it is stong enough- this could be examined with a tree auger-- don't quote me on the number but Stupsi the tree care hedgehog will tell you, its a book, a heck of a book.

Plant a replacement, removal is inevitable. Could be many years out though.

But dont ask me, I'm just a timberfaller.

You'd be amazed by what us fallers see still standing, but, then again, there isn't a target out there.

I know only ONE pruning cut... about 12" from the ground.
