Dude Am racking my brain to try to remember if I saw a failure from S. crispa... Will get back to you! The pics are not great, they were taken on a 35mm and all the best pics I had were in an album that I lost when I moved..(Am a ****!!) The remaining ones were scanned in on a Jpeg. Nevertheless it clearly shows a S.crispa fruit body growing from a Scots Pine basal area... Cheers mate!

Hi Chaps When I worked for Wokingham District Council, there was alot of Pine sp around a lake in a well used public area. I used to see P. schweintzii & S. crispa frequently... Since I've worked in a City in the midlands, I've never come across them or H. annosum... I have some pics, so will post them... It produces an extensive brown rot in the latter stages of colonisation in the roots and lower stem, so defo no mycorrhizal association... Cheers mates!

Learn to recognise the fruit bodies and their colonisation strategy and mode of decay... you may like to add these more coniferous based examples to your expanding list: Phaeolus schweintzii Heterobasidion annosum Sparassis crispa cheers mate!

Good lad Minty!

Hi guys I consider that this is a prime example of colonisation by Ustulina deusta (decayed wood yellowish - brown colour, Schwarze, Fungal Strategies of wood decay in trees) and fits my own findings. It doesn't matter anyway, the decay looks extensive and if this is the case SULE is 0!!! Fell & replace, be interested to see if it has the black zonation lines to see if I'm right..... Cheers Dude

Hi mate Defo Ganoderma, but could be adspersum, nevertheless colonisation statergy and mode of decay are very similar, so fair play to you. Do indeed inform the landowner, but as the esteemed Monkeyd states, what are the targets (if any??) If their is a target, ascertain extent of decay and determine the SULE!! Cheers fella

Dude!! Please stop all this wound painting, cavity cleaning and filling and trust the tree to maximise its natural defences (wall 4 barrier zone) to stop the spread of decay. Filling the cavity will not stop decay and stuff like concrete is poisonous, as detailed by other threads and is totally inflexible, the opposite of how a tree works!!!! Finally mate, get a copy of Shigo 'Modern Arboriculture' and learn about the tree as a system. Cheers dude

Monkeyed is spot on with the species ident!

Hi mate What do you reckon the SULE is for this tree? That will give you the answer on retention or removal and replacement planting. Cheers!

Sounds like the TO doesn't have a clue, an embarressment to those of us who do the job! I stand up to the fire step and give a definitive answer.... 1. The LPA had not made it clear that they consider the H/C exempt from the TPO because they consider it DDD (dead/dying/dangerous) If they considered this the case the application should be withdrawn and a notice sent to the tree owner explaning why the TPO no longer applies. They should not be altering the original app. 2. Forget about the damage to the SB. A minor accident like this would NEVER succeed in a court prosecution and the LPA legal dept would (if they were competant) just know there was zero point in pursuing it. Incidentally, such damage could only have a maximum fine of £2500 as the tree was damaged not destroyed. 3. As we all know, there is many degrees of B/C infection and many trees can recover and are safe to retain. 4. If the LPA are so concerned about the safety of the tree, then they should be using the legislation to get it made safe (note: I did not say fell!). They have powers under misc prov 1976 and high/wys 1980 acts. 5. The key to this situation is ascertaing the SULE of the tree in question!!! Hope this is useful...

I agree.. Rust is the guilty party...

Ok, the staking isn't great but they have left them tall to try and stop ***** snapping them off and perhaps more importantly, given the location, to help stop vehicles driving into them!!! How often are young street trees mullered by cars etc? All the time!! Nevertheless, the watering notice is a good idea, the odd person watering the tree could make the differance between life and death for a new tree. It also gives the residents some input into the management of the urban forest and a desire to see the trees succeed.... Perhaps!!! Nevetheless a step in the right direction.. also it seems to rain all the time at the mo.... so maybe overkill!! Will be thinking about implimenting a similar scheme... If it stops raining ever...

Very interesting post and some great pics... Nice one!!!

Nice one! I learnt something there! Cheers mate.

Hi Nepia A crown reduction would only create many pruning wounds on which the bleeding canker and other pathogens would use to colonise other parts of the tree. The removal of a large amount of leaf area would remove futher deplete energy reserves and the ability to produce energy on a tree already under stress. I consider this would put a tree with existing health problems into strain... I consider the key question here is not when this tree is a pile of sticks on the ground but what is its safe useful life expectency (sule). From what you've described I reckon a compeletly objective sule assessment would give it a rating of 5 - 10 years before major failure/tree death occurs... If this is the case then would it best removed altogether and a good sized replacement (14 - 16??) with decades/hundreds of years ahead of it... You may or may not agree, but would like to hear the outcome... Cheers mate

Hi mate Hopefully the infestation of aphids has peaked! I doubt that alone will be too detrimental to the overall long term tree health. Chers dude.

You might be right Tony!!! We both know the smell of bullshite dude...... Cheers mate

What enviroment were they growing in? Were they street trees? There is growing evidence that S. acuparia will establish but when maturing, their roots can't take the higher tempertures under tarmac/concrete.. There are many declining street tree Rowans where I work... They get to age 10 years+ and then decline & die. The research on the the root issues seems pertinant I reckon.... Don't forget that research has shown that the average temp under man made surfaces provides ideal root development temps... but it looks like its too hot for the Rowen!!

Hi David In that case you probably have a HC with bacterial wetwood and bleeding canker... Saw one the other day with a contractor... Pretty much the same situation you have described. Nevertheless he was confused with the canker & wetwood so it is important to know the differance. Cheers mate!

Great pics! Very detailed..

... a final note, the exudation from Horse Chestnut Bleeding canker has no odour. If you recognise the smell, that yeasty, fermentation smell, that it is likely that its the bacterial wetwood that you have found on H/C's before. It is a common site on H/C's and there's debate on if its bad/neutral or actually helps the tree health by creating an anaerobic state where fungi cannot live...

...and you know I'm far too lazy to get up that early John... Fair play to you!!

I agree.. The roots will grow towards the the optimum growth condition area (e.g the top 600 - 900mm) of soil once they get beyond any root guides..

I second that!! Bacterial wetwood... Don't forget there are many pathogens that cause stem exudation...

Errr... has the casual agent causing the stem bleeding been identified....? How can you diagnose the cure without knowing the cause...?? Such stem exudation can have many causes....
