  1. Totally agree with you Tony; I think we're on the same page. I'm with sloth re the lack of need for invasion. So untwist them undies ok? Jon (jomoco) i carry a big magnet on a stick, for finding survey irons and metal in trees. Not sophisticated, but it finds iron.
  2. From the pics it seems that dead limb you speak of is the/a central leader. Use a mallet or hammer to tap the crusty section. Now tap next to that and listen for the thud of solid wood. Also scratch that solid wood. If it is not green or white underneath it may be fairly dead. Don't mind jomoco; he lives in a dry climate and does not have to manage fungus often. He's an expert on support though.
  3. Very old (for here) Q alba gave up the struggle. I'd assessed it for an award 13 years ago, and it looked 'imminent' then. Absentee owner, unoccupied land, could not sell load reduction. Anyway I'm keen to poke around and see what's growing in there. Never did an ecological survey on this type of habitat before; not sure how. These undulating fans of response growth on the cavity floor just blew me away. Reminded me of coral growth out on the edge of a reef.
  4. Yes, recruits.. Does your rate cover a climb to inspect the main forks? And pruning/support specifications?
  5. Uh oh, this could get like ebay, only the bids would not be going up but down...

I do this three times in 120 degree increments around the wound. Something is buried in that trunk and girdling it in my opinion." Yes that line on the left does indicate girdling. Very nice protocol on severance of girdling object. Invasion only seems warranted if there is some sign of weakness imo. Or if the owner is not wanting reduction of that leader that goes to the right at a right angle. That crook is a more troubling condition and reeason for work than the bulge imo, and they may well be related; fibre buckling as mentioned. "...the wound appeared to be callousing evenly but it was difficult to see with all the stress growth and the awkward viewing angle. Any idea (anyone) what causes this growth?" Could be 'stress' sorry couldn't resist...
  7. Reports can take a little work or a lot of work. It's all in the assignment, and level of detail needed.
  8. Bears closer examination yes, but it looks to be extra strong at that point. No concern unless some aggravating factor, like a hollow sound under the mallet, or cracking, or oozing, is evident. How well is the wound on the right closing?
  9. Yes, the US leading the UK into the light, of veteran tree management. Isn't it ironic? How was the assessment different? The main thing was, it was systematic, whereas the previous reports omitted some key aspects. Here is his protocol: UC Berkeley Forest Pathology and Mycology Laboratory - Research The collection process seemed quite invasive when it was first described to me. I have not sent in any samples.
  10. The oak is spared, thanks to a comprehensive assessment by UC Berkeley's Garboletto, who agreed that pruning works would manage the risk acceptably. http://www.linkedin.com/redirect?url=http%3A%2F%2Fwww%2Emercurynews%2Ecom%2Fcalifornia%2Fci_24795820%2Fjack-london-tree-wont-come-down-scheduled&urlhash=zmoX&_t=tracking_anet National Trust, take note!
  11. The images of the Wellington tree showed that it lost its top(s) a while ago, with flat ~20 cm cuts. Wondering how these happened? If that's what the NT imagined would happen again, that makes their decision to fell somewhat more understandable.
  12. Cardboard. If weeds are matted and old, how can herbicide work?
  13. It's in Taiwan; 'Chinese' just referred to the language, sorry. It looks pretty sincere from here. It'll be interesting to see if mainland China adopts something like this, as it comes from their 'renegade province'.
  14. Good question David; "recently issued" is all i heard. Ran the first 2 pages thru googletranslate and got this Taichung City Government's Bureau of pruning trees Standard operating procedures * Taichung City Government's Bureau issued ROC 102 years in May * Foreword This specification pursuant to section 19 paragraph 2 , Taichung, parks and street trees requirements management autonomy empowers the Order Fixed , the city , the trees bring people many environmental performance benefits, including shade function , environmental quality function , Landscape function, traffic safety function, the function of natural conservation , disaster prevention functions and so on. However, the world's trees The greatest individual life , once in human life around the trees or broken lodging crisis , people will Poses a serious threat to life and property class. Therefore, in the urban environment, and how we want to so great Coexistence of individual life safety is an important knowledge that we coexist with nature . Compiled by the principles of this specification is as follows : 1 " trim " is the maintenance and management of urban trees important work . Pruning trees is so harmonious with the public , Work undertaken by the security along the important principle is pruning work must take into account ( 1 ) Members of the public safety Whole ( 2 ) . Maintain the health of trees and ( 3 ) . Reach the green function effectiveness . (2) The specification is mainly based on " 101 years of Taichung City Government's Bureau of Parks and doers of the word , Taichung City issued Tree management autonomy Ordinance " by " pruning trees Taichung City Government standard operating norms Research Project " Then compiles the work . *The normative content of dollars into six chapters, the first chapter includes pruning and other necessary purposes , including the repair chapter Cut parts classification and methods, Chapter III includes classification and methods of pruning intensity , Chapter IV , including pruning Safe period , etc. The fifth chapter includes pruning tools and security operation , including trimming Chapter VI Program Book descriptions of six chapters . Accordingly, the plan is to trim jobs over the basis of the three principles , develop standard operating regulations Fan , make Taichung City to become a safe and healthy green city. * * ** i * Taichung City Government's Bureau of trees trimmed standard operating procedures
  15. Was the tree's condition noted in 2012? "like a carrot" doesn't give a lot to go on. Pictures of course would help.
  16. Here's how they do it back east: http://163.17.209.253/dyna/data/user/g01/files/201307290828060.pdf
  17. You asked for qualification, ok. "David is definitely in the "keep the fungus ridden tree" camp" Where is David? "because he often has the option of intervention pruning Who doesn't have this option? "and removing targets and has a mandate to protect amenity. Our clients hire us to conserve amenity "That is a good and laudable course of action but for most that's not an option. BS. We seldom move targets, but we always prune and manage amenity. "Don't underestimate the population density on this small island, as tree surgeons, most of the trees we deal with influence at least one other property" Yes they add amenity to many properties. " and since we became a litigious society people willing to retain compromised trees are becoming a minority. BS. The majority want to preserve amenity. *All trees are compromised* in one way or another--Location, Structure, regular abuse by humans, potential pathogens by the score…Risk entrepreneurs who exaggerate compromised trees are part of this litigiousness issue. ''This tree has got a aggressive primary decay pathogen that will eventually compromise the structural integrity of the tree' BS. it will, or it MAY? Compartmentalisation happens; you have heard of this phenomenon? Perhaps less likely with this fungus/host relationship, but possible nonetheless. CODIT is more likely when arborists manage roots, but most of them don't. Slackers dismiss arboricultural options, and manage vegetation. " something is going to have to be done sooner or later. A throwaway comment if ever there was one. Is that sufficient qualification?
  18. How 'major' a surgery was proposed? Were those specifications included in the consultants' reports? Specs are often left out of reports seen in the US, diminishing their usefulness by leaving managers to fear the worst. Repeating Barrell's previous work done to his specs from the 1980's may well have sufficed. Why was this approach rejected? Not sophisticated enough for 2014?? Crunching numbers--based on blatantly bogus formulas, of data derived from imperfect machines, imperfect software, and especially imperfect operators (myself included)--is just one part of an objective assessment. Objectivity comes from direct observation and analysis of the living tree. The use of machines and mathematics, as in tomography and pull tests, does not guarantee an objective assessment. After all, the decisions on what to test, where, how, why, when, and how to analyze the results--these are subjectively made. Overreliance on machines and math while downplaying the tree's response and adaptations is VOODOO! Fears of 'spoilt appearance' were not founded on specs for proper pruning. BS3998: If, owing to decay or structural weakness, there is a need to prevent failure in a veteran tree, lapsed pollard or lapsed coppice stool, some kind of crown reduction (see 7.7) should normally be adopted as the main solution. 7.7 Crown reduction and reshaping COMMENTARY ON 7.7 Crown reduction alleviates biomechanical stress by reducing both the leverage and the sail area of the tree, and can allow retention of a tree in a confined space. It can also be used to create a desired appearance or to make the tree more suited to its surroundings. Unlike topping (see 3.28 and Annex C), it retains the main framework of the crown and therefore a high proportion of the foliage-bearing structure, which is important for the maintenance of vitality."

  19. If the job specs that you write are clear re cut size and quantity, should be okay. If all this is about walnuts being 'bleeders', mayhaps you are looking at a 'should' and misinterpreting it as a 'shall'.
  20. Yes that's more like kindling wood…something has to happen, sure, but maybe just a small saw, or just a pole clip. Every tree is compromised
  21. I think/guess so. That tissue is hardened. But why should they need to branch out, as long as the ends grow where they need to?

  23. I have 2 sweetgums L. styraciflua that i reduced overall with <2" cuts (because 3-6" limbs had been snapping off!). It is coming back nice and manageable; a thin every 3-5 years is all they will need. I would not make a 4" cut if at all avoidable. Remember, 15% off the end = 50% gain in stability. Less is more.
  24. And so sadly enough is the range of evidence to consider. Diablos ex Machina--use with caution, lest the mechanical tail wag the mental dog. The study is BIOmechanics. Response growth needs to be considered, and anticipated The tree should have a say in the matter; its life is at stake after all. Barrell's reduction work 30 years ago just needed to be repeated. Where did the idea that pruning would not be acceptable come from?
  25. Having used tomography the past 4 winters I can agree how the images can be shocking and misleading due to operator error, software issues, and flashy colors. Does anyone remember the jiggle that changed the fate of the Anne Frank Tree? Frank Rinn, who develops and uses these tools, calls over reliance on such results "voodoo" The Sep 2013 pic shows out was in need of pruning, maybe 10% off the crowded and overextended tips. The sight of that log confirms that condemnation was a horrible error. Why did it happen? 1. Too many consultant reports with mushy language full of CYA can be interpreted several ways. Edgy administrators will focus on the worst case imaginable, disregarding the rest. 2. Too many of us working arborists are skilled at rigging but not at retrenchment pruning. Dismantling uses big machines and earns big money now. The appeal of retrenchment works is too subtle and drawn out, not as exciting. 3. "Defect"-based formulas are deeply flawed. Target rating is overhyped. How many visitors are milling about the garden in a severe windstorm? etc. In the US, the Freedom of Information Act (FOIA) enables citizens to wrest such reports from agencies that want it all hush-hush. Don't Brits have a right to see reports on public trees? Or are you still treated like serfs by the privileged classes? All respect to Mr. Barrell for standing up and telling the truth. Please "Like" his video, and press for honest answers. Without looking at where this went wrong, it is bound to repeat.
