beech tree bleeding canker?

fell it

Similar situation here....

This tree is a monster and being that it is splitting in 2 and hangs over a driveway, it is coming down.

Anyone wish to hazard a guess as to what is causing the bleeding? also what we are likely to find inside when we cut it down?

I didnt find any fb's around the tree (beech) and apart from the split and the bleeding the tree looks to be in good health as far as crown vitality goes.

We will be strapping the 2 parts together for the duration of the work as a precaution and some of it will need to be dismantled due to soft targets (shrubs and other trees) and a stone bench that we dont wanna break obviously.

Any thoughts welcome:thumbup1:

all the bleeds ive seen in this thread= armillaria

[Fungus]

The orange stuff on both beeches could be coming from a Nectria ditissima infection on top of black bleeding caused by an infection with Armillaria cf. mellea rhizomorphs invading the cambium and blocking the transport via the phloem and xylem.

seems to be common for this kind of infection as all 3 of the trees in this thread have the "orange stuff" on my last photo you can see just a little blob at the top of the bleed on the right.

ive always thought of it as the fresh ooze as it progresses up the cambium as apposed to the older exudate which dries black.

Tony,

What do you mean with "progressing up the cambium" ? Isn't cambium permanent embryonic tissue without a transport function ?

Thats a fair cop, the phloem then

[Fungus]

the phloem then

 

Phloem = transport outside downwards, xylem = transport inside upwards, so the orange exudate would be coming upwards from the roots via the xylem (sapwood) bleeding from the trunk via the radial rays or from the top of a fresh saw cut of stumps as f.i. can be seen with Betula and Acer ?

But the mycelium isnt in the Xylem gerrit? its in the layer between bark (epidermal tissues) and the xylem, hence the cambial death?
