I dont, but repeated myself over and over is even more annoying! The fact is we arbs need to get scoped up to play these kind of diagnostic games, wether were looking at ganos, bleeds, mycorrhizea etc etc etc. otherwise its all opinion and speculation, and on that basis, its a question of whos opinion, ability/reliability & reputation you wanna take? no dont look at me, im shy!

and that is the long and short of it guy, whether you like it or not, and we have said it before:001_huh:

think about the logic behind your statement, laetiporus eats what? leaves behind what? the chicken would have been there first most likely, its part of the ecolgy of hawthorn habitats here in the u.k (neville fay mentions it in a paper somewhere) it has not interest in invading the cambium, or even the sapwood, its a heartwood rotter, only when T/R is approaching the limits do trees fail from laeti colonisation. the armillaria will have been a weakness parasite on a tree in decline and more rapid and complete in its colonising

almost a certainty:thumbup1:

white finger

probaly just moisture content similar at the time

brown and whit rot, mycelial ords of most likey a macro/lepiota species and black armillaria

excellent advise and post:thumbup1: treeseer, stick to U.S applications!

it is as they say, you gave a good dscription, new exactly what you meant, and boom there it is. sugar! yum yum

im up there 12 may, if ive got a chance I will pop in and have a look, pretty sure its australe though

take a small ore from the infected material and look for mycelia in the vessels my dear man, using a scope, of course. No ones tag teaming here, i answer to no one and have no affiliations, my opinions are my own, it just so happens that gerrits opinion is from a similar point of view, what YOU call fungicentric. I try to help, but you fail to hear me!

this is the revised "inclusional" version of that post, much improved with a little help from inclusionAL Pruning as a co-evolutionary process in the ecology of trees in the natural neighbourhood of human beings Trees are pruned - and prune themselves - naturally in many ways, both biotic and abiotic. Trees have depended upon and co-evolved with fungi throughout their life on Earth. As a group fungi are quick to attune to new circumstances and sources of energy, and have the capacity to breakdown ANY naturally occurring organic compounds, even petro-chemicals. But only some of them can digest particular compounds, such as phenolics and polymers, other than simple sugars and amino acids. It is therefore unreasonable to assume that fungal growth can be prevented anywhere as long as sufficient water, organic and mineral nutrients are available to support it. Correspondingly, although trees undoubtedly produce a variety of chemicals that protect and maintain their cellular structure and function, particular kinds of fungi are able to thrive in and contribute to the formation of habitats for themselves and other organisms that this production gives rise to. A wide variety of relationships between fungi and trees is therefore possible, and whilst some of these may at first glance may seem one-sided and detrimental to the tree, deeper ecological investigation reveals the truth to be much more subtle and difficult to evaluate in terms of simple 'cost-benefit' analysis. The evolutionary sustainability of any life form is precluded, not ensured, by the elimination of its habitat! Tree-inhabiting fungi should not therefore be thought of primarily as enemies of trees, intent on destroying them, but as companions of trees that ensure the growth, degeneration, decomposition and regeneration of trees in natural ecosystems, through a co-creative evolutionary process that Alan Rayner calls "Natural inclusion". It is when human beings intervene in these systems without deeply understanding them, that real damage can result. In many ways, it is human ignorance, not fungi, that should be regarded as the most serious pathogen of trees. Human beings need to understand themselves, trees and fungi as mutually dependent, co-creative companions in the evolutionary story of life on Earth, not as opponents.

thank you, Ive been meaning to start a thread deddicated to I. hispidus, shall work on that a bit later, it always fascinates me the differnces between fungi and location/species/environmental differences. Here it proves to be a fairly mutualy succseful relationship in many ash, not obviously that simple but you get my point.

true Gerrit, that hispidus is found on many other broadleaf species, but that doesnt alter the FACT that ash is its very much more common host and that on this host and on juglans too, it is responsible for loss of heavy limbs and subsequent re growth and retrenchments. So species specific actions, but non species specific host range?

why not, ammo? put any shots over my bow and prepare to receive returns!

Your digging a whole for sure, your doing work to trees without even diagnosing the cause of the lesions for a start, and making dangerous assumptions on the potential of the symptoms to be infectious. Im not suggesting I have the ultimate answer to this and a suitable treatment, but I certainly wouldnt be doing ANYTHING without first fully understanding what organisms and problems exist. I suggest you speak to Dr Olaf about how he is dealing with it. Guy, I dont like giving anyone a hard time, it makes me look like an arse, but you should know much better than this.

Hi all, anyone near seven sisters want to take on a small job:thumbup: for a friend of a friend so best behaviour and service required:biggrin:

yes they can, but only within limits, perennial and annual are very different!

Pruning as a natural co evolutionary process, and man as part of that process as an inclusion of the ecology of trees. Trees are pruned in nature by many forces, both biotic and abiotic, trees and fungi have co evolved throughout evolution, fungi no doubt present long before the trees. The fungi are quick to adapt to new resources, and have the capacity to breakdown ANY naturaly occurring compounds, even petro chemicals. It is simply absurd to assume that protection is possible, selection is another matter, for fungi need to posses the right enzymes in order to break down certain compounds. I have no doubt that trees produce various chemicals in order to protect celluar structure but that this protection is not absolute and in fact has evolved along with certain species specific macrofungi in order to "select" preferred species and so co evolution. There are many relationships in the tree fungi community that at first glance may sem highly one sided and negative in impact, this is however far from the truth. The relationship between trees and their species specific fungi, excluding non species specific "pathogens" is very complex and their ecologies are greatly interlinked. It is not in the species specific fungus own interests to kill the host, that is not a strategy for ultimate success, true success in nature requires mutual cooperation's or what Alan Rayner would call "Natural inclusion"naturally inclusive relationships" True pathogenesis is extremely rare in nature because it is a self defeating process that eliminates the host species, see dutch elm disease. Trees are primary producers, they also consume resources from the soil in order to make that product (sugar) they lock carbon up in their structures in huge quantities and convert the gas other organisms expire (carbon and convert it into oxygen) this is basic eco system cycling. If trees where able to avoid decay they would consume all the available resources and then die, they would be blind in their consumption (like us really) and die out as resources became limited. So the relationship between trees and fungi is quite simple in these terms, trees include fungi, and generally fungi don't consume more than they need. It is far from THAT simple but basically it is principle. If we understand this basic principle we can grasp that trees and fungi live in a stable but fluctuating relationship, if one or the other becomes too dominant they fall down and the other rises, this way balance within the forest ecosystem is maintained. There are many many different forms of relationship in this highly ordered but complex system, and it is all to easy to see only one side of the coin and develop a biassed view of the whole system. There are true pathogens, true symbiosis, and every shade of grey inbetween the two extremes. Co evolution is key in understanding the deeply complex relationships between fungi and trees. One such relationship that is easily observed and documented is the relationship between our Native Ash Fraxinus excelsior and the fungus responsible for its self pruning Inonotus hispidus, another in need of much research is the even more highly evolved relationship between our native white oaks Q robur/petrea and fistulina hepatica, both these fungi can appear at first glance to be highly negative. In one forestry journal this negative impact was desribed as "collateral damage via Inonotus hispidus" this is highly detrimental wording and shows a fundamental error in our collective understanding of the complex relationships trees have with thier species specific macrofungi. We seem to be very slow in adapting our views on these relationships, with a forestry commission article perpetuating such mis perceptions it is no surprise:confused1: I shall add images shortly but wanted to get the typing done before tea!

Hi all, due to reasons I wont go into Ive started this thread for a link back for images I am unable to show on UKTC so that I can link to them in specific relation to threads on the UKTC forum, feel free to discuss, but its more for that other purpose. I will say this, you lot are pussy cats compared to that crowd!

so that was your photo, I remember it well, this bares no resemblance tothe current image, did you show me this tree when i was at your place?

feeble effort!

that elderid roller C/saver is sweeet! bugger more cash to find!

yes its the dyneema kit, has the strap and new metal ring bracket all bolts tools and booklet.

Waz, is this tree public accses? im down that way 12 may
