Knock yourself out Stevie. http://www.rngr.net/Publications/neftic/26th-northeastern-forest-tree-improvement-conference-1979/decay-resistant-trees/file Try and get a copy of Shigos Modern Arboriculture. Some very good reference material on tree biology and anatomy. http://www.treesource.co.uk/acatalog/info_228.html .

I heard recently that the Goverment have told Scientists to not bother with any remedial work towards HC, as they have written it off in terms of it being a landscape feature within the next forty years. I've had a feeling for a while that this is a tad strong, and have now heard it from both Arborjet in the States and Glyn Percival from Bartletts here in Blighty, that Psuedomonas is treatable. Chemical bark sprays, sapwood injections etc....... As for Cameraria (leaf miner) it is as far as I can see, predominantly an aesthetical issue, as the Trees get the majority of their annual energy needs from photosynthesis early on in Spring, before the second, third or forth wave of larvae take hold and diminish the leaves ability to work efficiently. Having said this, the stress this puts on to HC's could result and possibly lead to secondary infections. Green lace wings are the answer apparantly. They'll eat any and everything in their path .

Are you refering to Alex Shigo's third wall (lateral) of the Compartmentilisation of Decay in wood ? .

Glyn Percival from Bartletts, believes that the lesions can be easily delt with by chemical bark sprays. Can't remember the trade name at the mo, will have a gander at my Barchams notes on the morrow. Worth putting up in it's own thread Stevie. .

Are you refering to psuedosclaratial plates? .

Doesn't beat Tony's legendary Seven ! http://arbtalk.co.uk/forum/showthread.php?t=3947 ...................but interesting and impressive nonetheless. Here's Four on a puny little Birch. Armillaria (rhizomorphs too desicated & not shown) Gano Pleutorus & Xylaria .

Ganoderma resinaceum decay information
David Humphries replied to stevelucocq's topic in Tree health care
Here's a Red Oak I looked at today. No sexy shot of the annual bracket I'm afraid, as someone whipped it away after I first saw it a few months back. As you can see, the Tree has a major lean and evidence of a previous root plate lifting. Carried out A Digital Micro Probe to help inform my management stratergy. Results show no decay @ upper root and lower stem level. Will proscribe a 15 - 20% reduction to help aleviate the over balanced lean, plus annual monitor & decay evaluation. . -
A few twinges where the miniscus is now partially gone, and the bones now grate a bit. But It's the bosses perogative to pick and choose when he climbs .

Here's what we believe to be Perenniporia fraxinea on Beech (!) from today http://arbtalk.co.uk/forum/showthread.php?t=6233 .

Great shots & site. Need to organise me and the team some work study program time at HF to try out some of them there crazy ideas we fiddle around with. Will you go back to check on the Hornbeam layering? D .

Official "Yank'" Picture Thread
David Humphries replied to GASoline71's topic in International Arborist Forum
Quality shot Jamin . -
Does look to be of Stereum type form. However, S. regosum as with all if not most Stereums, appear to be saprophytic on stumps or dead standing wood. Which would suggest ruling it out as the primary suspect for the failure. The wood fibres appear undecayed in your photo, can you elaborate on the state/type of decay present. Any more after photos? Good post .

Phellinus tuberculosis.................I think
David Humphries replied to Hannah's topic in Fungi Pictures
Does appear similar, and as Tony says, host is bang on. Sited on trunks and undersides of branches on both dead and live wood. Jordan has it listed as P. pomaceus, and goes on to give P. ignarius as having the synonym as Fomes igniarius Will consult & widen the scope at the office on the morrow . -
How close is that picture to Gatwick, Mick? .

Cool Had heard about, but not seen. Nice work & picture set Quickthorn .

Tried that 6 or 7 years ago at work. Wasn't successful. We got a heap of seeds and branches from an veteran avenue of Limes that was felled at Hampton Court. Tried inserting seeds at different heights of our Lime canopies, and grafting the branches, all to no avail. We've got absolutely no mistletoe in the local vicinity. Great find Tony. .

Nice work John. I see you take great pride in the finish of your work sites. Clean piles of cord & timber appear to be your trade mark, whether at work or down the woods. Something you were mentored toward or just naturally developed? .
-
Very similar to John here. Verbal assessment of experience & resume . Some leaf and Fungi Id, then invite the top two candidates back for a fell, climb and rig assessment. Can't speak for all LA's, but from my perspective I would advice to not climb flash or fast, also have a good base line understanding of topical p&d. Probably not hugely important, but shows you have a keen interest in what you're working with. Best of luck Treehugger .
