Any ideas what this is?

This white beams having a reduction soon and I just noticed this on it. On one of the pics it had a girdled root, could it be this causing it or are there pathogens at work hear? Any ideas?

[Roylance1988]

Pseudmonus? If spelt correctly?

[sloth]

Old damage to the trunk and poor rooting environment, honey perhaps...

[APC]

honey fungus i reckon.

[Roylance1988]

Probably worth looking for rhizomorphs then?

Well from a visual aspect it doesn't seem to be affecting the tree as the crown looks really vigorous & healthy.

Does this change your pruning assignment? I don't see why. Yes old mechanical damage, and good scarring, so it could be stronger than an undamaged tree/.

 

Yes the girdler is associated with the damage so add that to the list to cut.

[Roylance1988]

Reduction still going ahead. I guess as the girdled root is on the same side as the wound, then codet ain't working as quick as it should.

Thanks guys.

Agreed but there appears to be some seepage which requires some further investigation, like has been said possibly pseudomonas or honey fungus or just mechanical damage. The increased vigour could be the result of previous pruning and not always a good thing from my poor understanding the tree could be diverting more energy to regrowth and or is stressed, possibly.

 

I'd still go ahead and reduce sever the girdling root and sugest monitoring the wound.

Yes old mechanical damage,

 

 

With the necrotic bark retained and the callus at the edges underneath I thought it looked more like heat damage.

Considering the location of the wound reflecting heat off pavement I'd agree that is a likely aggravating factor.

 

As typical our hunt for a Cause in tree maladies leads to several suspects.

good plan to keep eyes wide open and attend to them all.

 

Excellent point Marc on not mistaking a nice crop of leaves as a sign of overall health.

 

The severe girdling on the exact same buttress that should be nourishing the dysfunctional area does not seem like a coincidence.

 

Just wondering from afar what the objective is and what kind of specifications for reduction are given for a tree like that. % overall, size and location of cuts, thinning included?
