Tree assessment/forest pathology

yes, i was just looking at it, it would seem to fit, it isnt dryadeus for sure.

 

so felling may not be needed, are there budget limitations here for defining the decay?

 

the tree looks to be adapting.

 

Hi,

Carried out a tomograph on the tree in 2010, some decay associated with bracket and area of flat bark, but not nearly enough to warrant removal. I have heard later ( thanks Gerrit ) that signs of selective delignification are not always picked up on diffuse porous trees.

Budget does not run to a pulling test unfortunately.

The tree has been dead-wooded twice in last 4 years.

diffuse porus is irrelevant here, this is a ring porus Q robur?

 

I wouldnt fell this tree, I would reduce it by 30-50% and give it time to adapt.

felli it.

I don,t believe you mean that, hama!

which part, getting my eyes tested or fell it?

:biggrin:Both mate, but honestly thanks for the replies I always come away from these posts having learnt something new or desperately searching through text books to clarify some point

So, they keep telling us oaks are resilient to armillaria, well they are no more resilient than any other healthy vital tree within good growing conditions.

 

This tree was dying back a fair bit one side, we went over to take out the deadwood and a little further back into healthier tissue. The client had asked for a reduction, we felt it was not prudent to do so at this time, we recommended the deadwood and monitor, i have also talked them into a mulch ring as large as they can tolerate. The idea being to adress the poor biodiversity of the soil and increase water retention. Then 12-18 months from now, if vitality is better we would consider a reduction.

 

I recognised the basal flare of I dryadeus, and eventualy found a discrete fruit body and last years old sporocarp absicion scar, these where very discrete and I had to really look to find them both.

So going back a bit to the smooth bark and armillaria, heres one i got in windsor great park.

smooth bark and Armillaria

 

Tony,

I can support your claim with about 50 photo's of Quercus robur not being resilient to Armillaria and reaction formation of smooth bark (callus) to (in vain) overgrow the damaged cambium.
