The 3rd pic resembles that disease; the first 2 look like physical injuries.

We though to start with the fitst two pics were phyical injuries but those are two seperate trees and both are also shiwing die back in the canopy, there are 4 in total showing the same symptoms and a fifth which is already completely dead

Many causes to dieback. Pics of canopy would be useful.

 

If a machine got close enough to wound the trunk, it compacted the soil, for instance.

 

Tree pests are primarily primates.

Ed , Everything i've read up so far seems to refer to it getting to europe and found 1 old observer article about outbreaks found here in Uk. If it does turn out to be the canker every article seems to be into not transporting the infected wood around. The Californians are big on it...

 

Has anyone else come across it in the British isles ?

Hi Treeseer if we're back on that job I will try and get some pics of canopy, Andy there is also a Guardian article referring to it from 2012 and also articles from Defra and the FC but neither have pictures and most of the information seems to be lifted straight from the American work on the disease with no pictures for reference.

Simply take a sample of the suspected infection wood to your nearest plant pathology ag laboratory for confirmation of the presence of the pitch canker fungus. Then present that report to your client if positive?

 

They'll think you're a pro arborist or somethin.
