Look how cool this is: Figure 1. Why spatial scales matter. To illustrate the situation that most microbes find themselves on leaf surfaces, assume a human subject on the island of Trinidad, which has similar proportions to a human as a bean leaf to a bacterium. Assuming that the human cannot move, has no vision, nor sense of hearing and is left only with its sense of touch and sense of smell, the immediate surrounding becomes vitally important. In other words, that human will not be able to perceive any other part of the island. This is comparable to how individual single‐celled microbes perceive a leaf. Without sufficient amounts of water, free movement of bacteria is restricted and they only perceive signals, such as sugars, amino acids or volatiles, diffusing to their occupied site. Thereby, the microhabitat conditions drive the experience and behaviour of individual bacteria.

The Pyhllosphere! :-) 'The surface area of the phyllosphere is approximately twice as great as the land surface area, and this environment provides a habitat for numerous microorganisms that colonize leaf surfaces (where they mostly form aggregates) and the spaces inside leaves.' https://nph.onlinelibrary.wiley.com/doi/full/10.1111/nph.15054

What's interesting is that fungi are allways present, they never will not be. They're just waiting for the environment to change so they can switch from latent to active. I think trees are more complex than we give them credit for. Just look into the numbers of life that live in their leaves (phyllosphere), it's insane! Ultimately arborsits would like to know the full extent of the structural damage caused by fungi. We're getting closer and an arborists approach must be holistic. However, not everyone has all the detection equipment to use to help assist a more holistic and accurate decision, this can, and still does mean premature deaths of trees.

The semi circular lines seem to indicate G.resinaceum. But the texture is more like hispidus. I'd go I.hispidus

It's good that a car park barrier is a host for life!

Says it infrequently found? May be no one records it/looks for it?

I thought IRATA/rope access deal with static rope systems only?

Give us some thoughts then Tony... Successfull CODIT? Host is rare? And why did it get the chop?

I replied to the wrong thread. Chill Tony...

But has the fungus caused root decay thus instability?

Great thread/post! ?

Did this tree fail?

Some interesting information on how successful fungal /decay detection by VTA is: Comparing visual inspection of trees and molecular analysis of internal wood tissues for the diagnosis of wood decay fungi | Forestry: An International Journal of Forest Research | Oxford Academic ACADEMIC.OUP.COM Abstract. The extent to which the presence of wood decay fungi in standing trees is underestimated when diagnosis is based on the visual inspection of trees wa

Cool!

Staverton in Suffolk?

Just proceed with caution, Ash die back causes necrosis of the living cell thus it losses its turgidity/water content which means Ash are even more brittle i.e anchor points are weaker, hinge holding/crown oscillation dynamics change etc. Some stuff here: https://www.ukfisa.com/assets/files/alerts/Safety Guidance Note - Felling dead ash - April 2018.pdf Arboricultural Association - Ash Dieback – Practice Guidance WWW.TREES.ORG.UK A range of tree related help and advice for members of the public as well as tree surgeons.

Gary, do you mean the T&C's for an ArbAC or general arb consultant?

Frank Rinn's certainly on the case! :-)

Nice. :-)

I made it to page 27 and couldn't do any more.... So I'm, here. Great thread, just a little too long for one night's read... ;-)

Here's a nice natural brace fusion.
