Today I removed a ninty foot Black Oak ..(Quercus Kelloggii)and about 36" in dia .

This fella had me look at this tree two years ago which then had the sighns of of Oak root fungus, but I told him to keep an eye on it because it was going to be a candidate for removal down the road.

Well here I am two years later taking the tree out. I went in earlier this week and did some inspection on the butt, were the rot was and dug out most of the insipiant wood. I felt there was about 60 to 70 perscent live wood left, but without boring I couldnt really tell. So I set the rigging for low impact.However this pics dont show alot .

first one job site

Thanks
Greg

Greg: did you take a picture of the stump after the removal was completed? I'd like to see it.

I appreciate it that you are sharing the various pictures of your days here. The pictures that you and every1 else provides makes treebuzz an interesting site.

Greg,

Joe must have jumped in before that last one was up /forum/images/graemlins/smirk.gif

Thanks for the shots. I like the fact that you showed the rot and then the autopsy report shot too. /forum/images/graemlins/wink.gif

It always seems to be that the rot is on the top-side of the tree. Why is that? Do you think that it is more dangerous to have it on the top of the lean or on the undeside?
 
I've have givin that much thought to, Mark. MAybe because it is more exposed ? I cant give you a good answer .

Is it more hazardous on the upper or lower side of the lean?
I guess it depends on the species I'm dealing with, severity of rot, how much lean, target zone and the amount of impact I will have on the tree while rigging.

Since I dont have a resistegraph or increment borer, I have to go on what I feel is right with some investigation. ( digging and prodding).But yeah , I know what you mean . If on the upside and the rot has gone potentially into the root system , will it up root on you ? if on the down side could it possible implode ?.

I guees it's like a limb on a tree. Depending on angle,size,weight, attachment, tapper and whatever else we consider, we know that if rot is on the upper side of a limb it has more potential for failure. Underside not as much.So considering the amount of rot ( insipiant wood) is it hard , soft, still traveling and all the above reasons, depends on wether the limb is going to fail or not down the road.

I try to use reasoning to the whole tree and a 50 to 70% ratio (Rot) to height , weight and lean . If it's in this area I have to really consider climbig it for removal. Thats when I turn it over to someone else.Thats for PVT work. Unless my purchase and rigging can be from another tree.

Anyway , I'm sure you know all this , but I thought I would give you my take on it .

Thanks

Great Pics indeed!! The last one was an eye opener.

A complete cylinder (hollow tree) is quite strong, however as soon as there is a void on the edge of the cylinder, the strength drops dramatically. Like 60%

I tell this to my customers all the time, (its my job).... take an empty toilet paper tube and stand it on end. You can stack a bunch of books on it, no prob. Take that same tube and cut a 1/2" v-notch in the bottom. Not a chance of stacking the books now. Its scary, but something we can deal with. Thats why we all are the best at what we do.

I know this tree was not totally hollow, but look at that last pic of the stump and think about that. /forum/images/graemlins/shocked.gif
 
Nice pics. I have 1 suggestion. If you already did this, please forgive me, but I didn't see it in any of the pics. Install a hold back rope or 2 (V rig) to adjacent trees on the back side of the lean. If the tree cracks or starts to crack, the hold back ropes will hold the tree in place. If there is nothing to tie it to, we have used 4 foot ground anchors turned all the way in.

Just lookin out for arborists safety.
 
Tree dr, good analogy. I have never really though of it that way .

Norm, good suggestion and i might have done that if there was a tree on the back side of the lean, but there wasn't. Being the type of tree that it was, I was confindent that it would hold up .However, as they say, better safe then sorry .The whole tree was rigged from another with exception of the secoundary line to keep the heavier pieces from swinging to far.

Thanks
