[Rod]

two more pics

[David Humphries]

It has the appearance of either Ganoderma applanatum or Ganoderma adspersum/australe.

 

This may indicate the presence of an intensive white rot.

 

I would advocate further internal investigation. Picus, Resistograph, Digi Micro Probe ect.

 

What are the targets, Is that a drive or a foot path in the photos?

 

Also looks like it's on a Sessile Oak, judging by the leaf stalks.

its over a drive but nothing else

the chap who owns the ground has us in once a year to do deadwooding bit of haloing and other such things(general tidy)

 

the tree in the pic is not entirely healthy it has a central upright limb (still alive) with rot creeping downward but it has been reduced around two years ago and will need removeing in future i expect.

 

also found what i think is a newly emerging canker high in a limb over the dirve (pic bellow)

 

the owner loves his trees and thinks some are circa 1816 i think he said

his family have owned it since 17 somthing
