Weird and wonderful Jerry, what exposure was it on? .

Tis the season to see Fungi, fa la la la la....
David Humphries replied to David Humphries's topic in Fungi Pictures
Ganoderma species I would plumb for G. applanatum (lipsiense) due to the thin rim, surface, flesh and tube layers, pore surface, and the location of fruiting from out of a wound. . -
Imagine they are different positions from the same tree Paul .

Thanks for posting the link, it's appreciated Nice touch encouraging visitors to take a piece of the wood Still feel it's disappointing that the option of not bringing it down over time (whilst new ones establish) was not given a go. .

Rest assured it has been considered Jules. But that's not a debate for here and now. .

The employment threads were changed to stop silly replies that often went off topic. If anyone is interested in an opportunity in the employment threads they can contact the OP by Pm or phone number/e-mail if they have been provided. .

Intrigued, on what evidence would you condem them ? Guilt by association or gut feeling? .

Matt Baker on Countryfile just now, up a tree in Westonbirt with an Arb looking at a tiered bracket and ' listening' to the decay inside with a soft faced hammer .

There maybe root grafts that could be conduits for the mycelium of the Meripulus, particularly if there is already dysfunction in the roots. Also there may be additional wind load on the remaining three canopies to consider now that their neighbour has gone. But personally still think that this is a bit of an odd decision to make. .

Sounds a bit knee jerk from the way you have described the situation. How close were the trees to the failed tree? .

We've only tethered trees to other trees, like this veteran lapsed beech pollard, which was cable braced to a couple of adjacent maidens but I recall an example (similar to yours) in the Basque, an area where they give more stall to their 'useful' trees . This fairly mature Walnut had blown over completely in a storm and broken a number of roots, they had it winched back upright and cabled on to the building. Tbh, I didn't look too cloely at the brackets on the building, but I'm sure suitable ones could be procured fairly easily at a hardware shop. This cabling had been on the tree for a number of years and the tree was in rude health I seem to remember and fruiting well.

Static Load testing is one way of assessing tree stability. I've only ever seen demos but we have one or two trees that we have penned in for a pull test at some point. Tree works environmental offer the service Tree Stability Assessment It involves placing a known load on a tree and measuring the movement of the root plate and stem via inclinometer readings. .

I suspect that the tier of brackets on the stem are a Ganoderma species and not Polyporus squamosus. Polyporus have much larger pores than Ganoderma species (even at the magnification in these shots, it's fairly clear) and are stalked and more often than not growing out of a cavity, fissure or open wound, unlike the ones in these images which appear to be emanating from the up damaged trunk section. I too agree that further assessment of the brackets and the associated decay is required here. Without wanting to derail this very interesting thread, I'm intrigued with your 'miracle' statement Jules, regarding the P. s failure you attended. If you wouldn't mind, could you pm me with the details of the time of the incident, weather conditions and type of target associated. Would appreciate it, thanks .

Fine piece of editing Rob, I imagine it portrays the essence of the trip really well. The Ants were undoubtedly the real stars of the show .

So in essence, from what you have shared regarding the history and the visuals, you appear to have a tree that is leaning toward a target, has severed roots, a lifting root plate, damaged basal region with associated dysfunction between the roots and the trunk, decay (possibly coalesced inside the trunk) from non-occluded pruning wounds, and a weak main union...........and unconfirmed reports of unknown fungal species at ground level. Mmmmm, I can guess what the majority of people would say However, if the tree is still vital and can continue to put on a canopy of photosynthetic material and the client is of the opinion that they would like to retain it for aesthetic and cultural reasons (and is willing to provide a budget and have it regularly monitored) then a canopy reduction and bracing/tethering to the building is an option in my opinion. Edit.....beat me to it Ross .
-
Any notion as to the species of fungi that has been seen at the base? Do you have any images of the union and a context shot of the whole tree and it's lean toward the building? If your images are on a hard drive you may have to resize them before uploading 800 x 600.

Fantasmagorical Marco Now that's a 'tree house' .

I'm not referring to the above incident specifically but in general. It's usually always a very an emotive issue. It can and does remind friends and families of where and why their loved ones got maimed or passed away. Btw, I'm not advocating this approach particularly, but I know of instances where this has occurred. On one particular occasion a fatality occurred during a head on collision with a willow and the stem really only sustained a relatively small amount of bark damage by the car with no specific structural issues, but it was still removed. .

Not entirely sure it will shrug it off, as more often than not trees involved in serious Rta's get felled ime.
