More consultation ... like the TO considering something besides felling. Trenches dug right next to trunks are terrible, but there are a lot of options.
-
Great responses thanks. Rob it appears the majority of UK voters so far would agree with you. No comment on the US polls That middle purple cut may not be needed; it depends. Re specs yes good points on the need for additional guidance: I typically might say ~"...reduce branch to clear (the dominate) leader by X feet (1 or 2)" if subordination is the purpose for example.

In the US, 'heading cut' has 2 definitions. One is 'internodal' the other is 'to a lateral <1/3 the diameter of the parent.' Confusion is inevitable, but the 'heading cut' concept remains prominent in training materials. So if the objective is to reduce the branch to reduce its growth relative to other branches, maintaining long-term health and safety with minimal maintenance, many US arborists are trained to obey a '1/3 Rule', and make the cut at the red line. In the UK, this term is not used. So if the objective is the same, where would UK arborists make the cuts? Article Request Page is some research that seems to indicate that red cut might not be the best.

Liners for gloves recommended--worked through a few winters in Wisconsin (near Canada) and frostbite snuck in before I knew it. Now my fingers turn yellow when chilly; not a pretty thing.
-
The infection seems to have begun in a sinus (concave area), where mechanical damage would be unlikely. Perhaps self-damage from included bark is a factor.

It's not too rare in the US, but not so common that I've seen a pattern to its occurrence, or tried to ID it. Very bright white! Aleurodiscus and Perenniporia are the most common bark fungi genera here; does not look like those. ID is an academic question, as it's never been associated with damage ime.

PiCUS Sonic Tomography : Degree Dissertation Project
treeseer replied to Rob Murison's topic in Tree health care
Very PICUS-centric; are they funding this study? Q 11 allows for no other tomograph. Tomographs do not detect decay; they measure wood conductivity. You've seen this thread? http://arbtalk.co.uk/forum/tree-health-care/5089-decay-dectection-equipment-7.html pm me your email if you want a study on tomo use. -
Kd is endophytic; it can pop out anywhere!
-
Do any branches overhang your property? If so you can prune these. The registered letter, copying the TO, the railway, and a solicitor, would be the next step on this side of the pond too.
-
That main fork does not look that great from here; maybe a probe around that potential split? The flare is all above grade so RCX may not show much that is new. If Arm. is a serious potential issue then improving overall site drainage, with deep aeration, swales etc. may be in order. Buds swelling should not inhibit pruning. Wounds made in spring seal better than those made in winter. (Dujesieffken) Yes maybe hold off on less essential work til late summer. Looks like a fun project.

There wasn't a failure, lucky all around.

Interesting to read Fungal Strategies p. 112, then read the posts here.

Agreee nothing to worry about. the Dendro article tried (but failed:blushing:) to bust the myth that compression/tension wood was an either/or kind of thing. It's all reaction wood, and when you really think about it, all wood is reaction wood (quoting researcher Frank Telewski).
-
Past threads here on this 'braided reaction wood'. Cassian's piece on eucs; http://www.naturaculture.com.au/sites/naturaculture.sites.go1.com.au/files/Specialised%20Self%20Optimisation%20of%20Gum%20Trees%20-%20Braided%20Reaction%20Wood.....pdf A US beech story attached washboard cassian poles.pdf Detective Dendro - The Case of the Wonderous Washboard.pdf

Tony, do you think those are the last remaining uninterrupted vascular pathways? The rest of the bark looks normal; the conks are confined to a sinus. What does "the remaining shows none" mean? the remaining what? Robinia is fairly aggressive in my experience.
-
In terms of effect, note the response growth. Orange pillars on either side of the conks indicates a strong Wall 4 compartmentalisation. But it does call for further assessment.
-
That all makes sense. From a US perspective, I can climb alone with just the client there to call 911 (emergency svcs) per need, plus our insurance sounds more affordable--E&O is <$500USD/year. Glad to hear you include full specs.
-
Boy, you guys got special vision!
-
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.

Please help me with whatever is killing this Eucalyptus tree
treeseer replied to munksapprentice's topic in Fungi Pictures
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. -
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.
-
Yes, recruits.. Does your rate cover a climb to inspect the main forks? And pruning/support specifications?
-
Uh oh, this could get like ebay, only the bids would not be going up but down...
