Girdled roots

[David Humphries]

but doesn't that cut section look like an extension of an old sgr to the right? It may have 'jumped' up from the point of grafting?

 

Possible I guess.

 

Removed it (by hand) in part to see if had grafted to the root bark below.

This ones perhaps beyond caring about its girdling

Looked alright in the first two pic's,

 

What's your plans for this one?

[David Humphries]

Not one of ours, this was at Richmond Park

 

The habitat & biodiversity value of this one is what's important here.

 

Was there on an FC inspection training day for OPM (see bino holding attendees in the background)

Guess I'm currently tuned in to every girdle potential that comes across my sight line

 

Should start remembering that there's more to this tree health pulaver :

Yes there is, but stull, if that habitat is good to have above the ground, then root pruning might keep it vertical longer.

 

Hoping opm situation is not too dire at richmond park; i saw none there last summer, but was not looking for it really. the mgtr. at syon was as good as it gets ime.

Could it also be that in this type of situation (habitat) the girdle may provide some additional anchorage to the butress?

2012, there were reported to have been 800+ nests recorded from the previous year (did you not have your glasses on? )

 

I understand the recorded number for last year was substantially higher than the previous, in to the thousands.

 

Contractors are now in the progress of spraying (Bt) though this is weather permitting, which is not particularly good currently.

 

Only looked at a couple of trees yesterday near the training facility and lo, there were last years nests that have been missed.

 

Shot 1&2 same tree

1 old nest spotted by an eagle eyed inspector.

Tbh, there is no way I would have seen it in that location.

 

Shot 3-6, would certainly make life easier if all nests were as easy a spot.

 

Shot 7-9, cluster of individual old moultings from last year

 

 

OPM is a sneeky little lepidoptera

"Could it also be that in this type of situation (habitat) the girdle may provide some additional anchorage to the butress?"

 

As in, strapping it down somehow? I don't comprehend the physics that would make that work. But yes on a tree like that, retaining any but the most obviously detrimental would be prudent.

 

"2012, there were reported to have been 800+ nests recorded from the previous year (did you not have your glasses on? )"

 

Well my glasses were focused on other things. Being my first time there i was quite the awestruck tourist.

 

"OPM is a sneeky little lepidoptera :sneaky2:"

 

Yes good binoc skills needed there. I rather fancied that big vacuum cleaner they used at Syon; cleaned up the nests it could reach quite nicely, well worth the soil compaction. I hope the writeup was accurate.

Perhaps this could (or is) being applied to the assisiting of anchorage of dead standing timber?

 

Steel wires layed over 'flared' durable butressing & drilled/inserted to depth (?)

The exact opposite of this, where the tree was being used to 'guy' a hunting platform in the Basque with the wires going around the roots.

Finding this thread extremely interesting, and enjoying the learning experience - great stuff

 

David, I have within my garden a Cedrus atlantica Glauca which appears to have girdled roots and would appreciate if you could give your opinion on this.

 

Pics below.

 

This tree did have a lean on it towards to right of the photo for many years and the 'left' side of the tree appeared to be the weaker side. The girdled roots shown are in fact on the right hand side of the tree (going from the pic below) and I wonder if this may have contributed to the issue.

 

In the last 2 - 3 years its pulled itself back upright once more, do you think the exploration of the roots and the removal of the two girdled roots would help this tree?

 

Many thanks, James
