Bundle 2

Lichens present in addition to the canker yes...The bark looks to be still reasonable thin (immature & smooth, typical of ash-again, yes, ash!) but with the appearance that it is dessicated....breaking into a mosaic of yellow discoloration...Not seen similar before. Site is north facing, some 400m from sea..

Cheers!

cheers Tony!

Any one care to speculate as to the cause of this? (Bark discolored, yellow and cracking in mosaic or grid...I see the canker but think it unrelated..) Tim

What do we think this is...? (Not seen it, this the only image) cheers

Those numbers, indeed the the formula, are referenced to "Fraedrich & Smiley – Smiley & Coder 2001."

Is that aimed at me David...? edit: Sod it...... this looked promising:blushing: Filipa Cox: On fungi, trees and pollution. Björn Lindahl, Uppsala, Sweden. ( a leading expert in forest fungal biodiversity and function)

Kinda thought this bit was pretty relevant....(included above) "• More information is needed on the effect of repeated pruning to determine the impact on the root system and soil moisture conservation at the periphery of the root system." It's not insignificant that LTOA have a risk limitation strategy that utilises this technique, coupled with a cyclic regime of pruning...Its equally relevant ( all i was trying to point out) that nowhere else sees the need/benefit (as you like). It is of limited occurrence. I am not making any comment, as far as I am aware, as to how effectively the research has succeeded in answering its own remit. The implications are obvious......Lets have trees that are all mullered to within an inch of their lives..(every year) at some cost because it is the only solution we have for a very specific issue relating to 1% of trees? Or is there a better way? Plastic trees anyone?

"The cost of repairing the damage caused by the failure of domestic house foundations, due to subsidence, was during the years preceding this project of the order of £300-£400 million annually. Not all of this can be attributed to the presence of tree roots. However, most of the subsidence incidents in the UK are found to occur in areas with clay soils and in these areas, tree roots are claimed to have an effect on subsidence incidents in 73% of cases (Loss Prevention Council, 1995). Hence the potential for saving on remedial costs, by reducing the need for rectification work, may be around £200 million per annum. Currently, no methods exist that reliably predict which trees may cause damage and not all trees near buildings are implicated.- " There are approximately 100 million trees in the urban environment. Of these, a large, but undefined, proportion is in sufficient proximity to a building to pose a perceived risk of damage. However, even in a drought year, the number of actual cases of subsidence is only about 50,000. The risk of a tree causing subsidence damage which is related to species, foundation depth and soil type may therefore be less than 1%. If one could identify this 1% with any reasonable accuracy, they could be pruned accordingly.- "If trees that pose a risk cannot be identified, then one alternative is to treat all trees, regardless of the risk they pose. The environmental consequences of this would be catastrophic; nor could there be economic justification for any such policy as the cost of recurrent pruning would far outweigh alternative methods of remediation. For example, even pruning 1% of the tree population could cost any where between £50-100 million." I guess its a question of perspective and the degree to which resources are being subverted ,disproportionately, to subsidence claims....? It also says.... "• More information is needed on the effect of repeated pruning to determine the impact on the root system and soil moisture conservation at the periphery of the root system. • Root restriction within geotextile membrane lined pits may be used as an effective method for controlling shoot growth, but more knowledge is needed on the long-term integrity of the membrane, the stability and the performance of the tree...." The LTOA would seem to have a significant data base aswell as the march on any other body likely to accrue meaningful statistics..?

I have noted the same thing.Typically the result of storm events, so higher than average winds but importantly, often associate this with very wet soils ( FC +) Shear failure of roots..... Thanks Sean for provenance detail as I has suspected anatomical "adaptations" to climate and endaphic factors responsible....Not very likely! Good link! Tim

Not good news is it?

Just want to stick my oar in to say...I would hunt down "Fungal Strategies of Wood Decay in Trees" by Schwarze, Engels & Mattheck (isbn3-540-67205-2) before getting the "Manual of Decay"....It is a better book, more breadth of information and detail.....the thing is, you can take it or leave it (in the sense that it can be easily used as a reference for specific fungi/host relationships without getting bogged down in the more scientificdetail), use it as a reference and or dip into the early chapters for crucial info about wood anatomy and fungal strategies in the round... Im sure Hama wont mind me saying this...Top book. tim

Erudition - Wikipedia, the free encyclopedia "An erudite person has both deep and broad familiarity with a certain subject, often gained through study and extensive reading of the subject's literature rather than formal scholarship."

", is this a fair assumption?" No mate...you're reading way too much into my comment. I merely asked as you are far more switched onto the fungi than am I. ( you seem to think I am more than the underachiever I am my friend!) Please stop putting yourself down. i say less as I frankly have little of significance to say! Rewind matey...You gotta let go this obsession with what other people know, think they know and so on. I am sorry that you haven't grasped that I think your contributions to this site are great, much needed and , for me anyway, regularly transform the topics of forum posts.... I have followed many of your threads as i find your perspective to be hugely entertaining and knowledgeable. That you didn't go to skool or whatever is the problem, only enhances what I take from your erudite observations..... Now, can we just forget that I piss you off and get back on topic ....?I have already said it has the makings of a great thread, and so it does!

Xerses....Talking/listening to Glynn Percival last week. He's fairly convinced that the airpick/spade is more use for decompaction than the terratree. I think he cited Ed Gilman as a source for reference here....Hes done a fair bit with massive blowers and structure/stability also....Google is your friend...!

Jesus.....insane, pointless and very rude! That's on private property innit? You been upsetting the locals David? i know local authority bods have complained on here before about this sort of thing. Ill be honest and admit I thought it was just a bit of whinging....I kinda need to reassess that eh! That' not even casual vandalism...every branch!

Nice one! Its been habitat once or twice by the looks ! I didnt til you marked it out...it's a fruit body I take it? (Could be a snail for all i know!)

Fair enough....you'll just have to ignore my illhumoured hangover! I recognise the Pholiota from that set..and of course the Fomes, although aware that it may be a gano...The bolete (?) and the others are puff balls (Lycoprdon/Sclerodrema)neither in the directory eh! Shot 6 is a stunner! Stalked puffballs * Battarrea phalloides * Calostoma cinnabarina * Pisolithus tinctorius * Tulostoma Simulans

Still not naming your fungi David!!

The association of "rare" and cuticularis likely makes this observation scantily verified....Does oak or other "thicker" barked tree species not host Inonotus cuticularis? Wrinkly socks are for wimps but do you really see it in other species so readily? Beech are great for this...as are the eucs of Australia.

Mate...the weather kinda put the mockers onnit. There was no way once I saw things sat am! Too bad. There was some tree related stuff on the bill too!

Hi Sean, Do you use this criteria for claims of this nature in Australia, either directly or as a point of reference? I imagine that certain of the issues are the same but that foundation construction is not really replicated between the two locations...? Tim.

Its outrageous! So called fair society...This govt are talking more crap than the last lot...and that's going some! The train operators sat there last night telling us that its only 6% increase...except its 10-12% where the trains are busiest, most crowded, and fares are highest.....(S/E) It's not fair? It's not a circus either ! I think it would be a wrong turn for TPO legislation but in particular, would do no good atall to the public perception of trees.....and those trees owned and TPO'd. There are some things we are simply going to have to accept as needing paid for...debt or no national debt.

Subtle nuances relating to the classification of bio-controls and fertilizers in the "licence" application and declarations I would n't be surprised...Basically, fertilizers ( so termed) are a heck of a lot cheaper.... Perhaps Dan will enlighten us....
