No nor have I ! thought it was only seen only on ash, but it was an old stubby step cutt with ash in the surrounding wood so I guess that is why..

go on........... plz

 

 

i want to know more

 

well thats basically the bare bones of it.

different tissue boundries form reaction zones that produce chemical barriers that resist infection. the strength of the barriers depends on there location.

cheers

 

i kinda got the compartments part

 

i was interested to know more about how the numbering works

 

like where is number one (obviously its not evedent on the numbered pictures)

 

is number two always near the outside

 

that kind of stuf:thumbup:

 

or i can wait and read the books (which ars 25 miles away in the office)

1 up and down the vascular system

 

2 between the annual rings

 

3 between parenchyma(medullary rays)

 

4 after wounding the newest live tissue creates forms the 4th wall

Beech.....has meriplius and beech bark disease...

How far up the trunk did the central decay extend Sean?

More to this than merip! combination, maybe a pholiota present cuasing the internal cavity

[sean]

These are pictures of limbs......we monolithed the tree to about 6mtrs at which point there were no signs of decay. Had a couple of limb failures in the past quite close to stem so can only presume decay has spread to the limbs you see here.

[Tony Croft aka hamadryad]

There is a fungus i suspect of being able to cause this level of decay high in the Beech canopy, Pholiota aurivella, the golden scaly cap, the pholiotas are know cavity formers in butts but little is recorded of thier upper canopy capabilities.

 

i have some great shots of Aurivella up to 20mtrs on beech limbs, both from epping and whippendell woods.

 

I believe these may decay the internal structure without too much invasion of functional tissue and facilitate a more controled failure of trees, a natural retrenchment prune.

 

something many seem to find a preposterous theory!
