agree that shroom looks saprobic. the stale cider infection is not fungal; see attached; i cleaned one of those just yesterday. Ooze in the News from TCI Magazine 09-04.pdf

It's the $%^&*(&^%$ grass that is doing the damage! Get the @#$E%R&*%^*$^&%YT$#@^$ soil off the #$%^%$^ stem!

Gorgeous color and spalting; a woodturner's dream. And now it will burn to warm a thief's asp. A double crime!

Lots of green leaves in that pic--what was dead about that weight? If this incident does not make aerial assessments more routine, what will?

For any root decay fungus, I reckon removal/replacement of soil from around the affected area, aeration beyond that, and inoculation with beneficials, and managing mulch and moisture, couldn't hurt. Just potential treatments; whether to specify these depends on the objective.

Over the top and into the moat. Designers and managers who specify and manage grass up to bark are inviting damage. Discipline them, tough guy! Strimmers are not scissors. Has no one heard of mulch, or herbicide?

Looks like 2nd pic is the good side and the first was the bad. use trowel and hose to clear the sgr then prune it...September 27, 4 p.m.. is that opinionated enough?

It would also be good if more of that material was more easily available! I'd love to see the Costello piece; he's a fine analyst. That was written over 5 years ago; Mr. Phillips might express less uncertainty on much of that today.

same general rating of I.d. in the US as well, although I would hasten to add there have been cases of unanticipated uprooting. But these are rare, and only on trees with unstable, sprawling, unmanaged crowns. Entirely agree with your crown strategies described; what about soil works in response to I.d.? O and very nice quote from the UCLA coach.

Those droplets are distinctive ime. does the presence and name of this conk affect your management of the tree?

Beautiful work; truly awesome! Belongs in a textbook.

It is a gorgeous asset. Looks like acorns were green; at the heaviest stage. How much was reduced?

The girdled buttress root appears to be broken and decayed. Curious. Pruning opportunity. Possible to see all sides of it?

Well there I did it; I hate the term 'stress', but lazily used it. I'll go back to focusing on overextension, and let the academics muse and ponder on water movement and tissue qualities and other less visible aspects. zipindelip

explain this phenonomon. Wood weakened by moisture stress, ends too heavy. What else to say?

Practical farmers have shovels--that's the only tool needed, tho a trowel and hose can help. Just dig the weeds and soil away from the infected part of the stem--takes mere seconds to see extent of dysfunction. Why does "soil work" connote "expensive tool--arborists no can do--we climb and cut and that's all"??? Far from the truth.

"I would buy into the "over extension" of large horizontal branches. But many Oak and Beech appear to carry large apparently ridicuously overextended branches without incident." Hence the difficulty in prioritising which limbs to reduce. Exposure to weather, and targets, seem to matter most. "I did note in the failure that I photoed that a crack had formed and age weathered in the tension side. I also note this in at least one other photo" Good point; aerial inspections should take a close look at these areas, known as 'hot spots', on long limbs. right around where Massaria colonises?

O lovely the big toy is out so a splendid time is guaranteed for all. Bollocks.

Job #1 is to improve soil drainage, right?

Thanks for dredging up the article. Some good guesses on causation re transpiration etc., but every case I've seen, the branch was outside the crown outline and overextended. So it can be chalked up in large part to gravity. (Brilliant huh?) Makes one believe in periodic reduction of sprawling limbs over public spaces; a 5-year cycle perhaps. Especially with previous occurrences. It's easier to prioritize based on probability when one focuses on the single factor of sprawl, but not easy nonetheless. The 1983 management options seem a bit draconian.

Before any more 'burning' thoughts come to mind, consider that the infection appears to be in one vascular pathway. I heed the teachings of Prof. Croft--See trees as a series of units. That pathway may be infected and compartmentalised, long-term. The story is told underground--check the flare and roots!! NOT POSSIBLE to make a prescription, Rx, without a Root Collar Examination, RCX. If the infection is not widespread, one strategy would be soil replacement.

By rectified I mean dealt with the constriction on the buttress by girdling root." Understood--dealt with yes, rectified i.e. made right, not quite. " An exploration of roots below ground would be interesting but why, when the tree is in fine health, go and create extra wounds for possible infection. Don't see that there's a need personally. Warren, look at the infection court in the shredded ends of that root. Two neat pruning cuts further back would lessen the amount of exposed area. 2., trees respond quite readily to pruning in this basal region of high vascular activity. A generalized 'what if' should not inhibit a further attempt at true rectification, whilst finding out 'what is' in the bargain.

Call me the Creature from the Brown Lagoon! Snorkels with filters recommended. All good with me, if the roots have room to grow.

A list is on page 52 here ArbNews_2008_06.pdf

"Oh, please let's not! Agreed; that battle need not be repeated, as it was clearly resolved. "The correct term is Decay, because that's what Sgigo said it is. WHta is now being debated is whether Shigo was right or chose the right word, that's a different matter. Fortunately, those that have read his works or learnt of CODIT second-hand get the important point that trees deal with wounding damage by hampering the spread of resultant decay/dessication/drying/wetting/dysfunction (walls 1 to 3) until they can effect a permanent repair by occluding the wound (wall 4). Which D to use is a tangential and semantic battle, though I agree with Tony the distinction is important, on another level. Is every Shigovian version correct in 2013...Alex would be disappointed if they all were so considered. "Hopefully that's the way this Beech will go, but the race is on. What I have always been a little unclear on , despite woute a few Shigoesque dissections I have made across partial occlusions of infected wounds is the extent to which the action of a fungus like P. squamosus will interfere with the occlusion. That is to say, in a straight race the occlusion should be complete before the fungus has done critical biomechanical damage, but if the fungus is also letting the tree's tyres down to get a head-start, it must become a different race. Perhaps, but one must also consider walls 1-3 letting air out of the fungus' sails, to introduce another torturous metaphor. Strategies are simultaneous; fascinating stuff, but he potential in both sides must be accounted for, to be close to accurate. We guess more than we know.
