Red Maple with Kretch

[treeseer]

Assessed this fellow yesterday. 2nd pic south side. What is the scuffed brown area all about? It's totally dry and looks like abrasion, but I see it on oaks etc. where abrasion is impossible. Typically on compression side of compromised trees but not always.

3rd pic west side; root killed by grading is being digested by adventitious roots. Client asked for remove-or-retain opinion; strong response growth leads to specs.

Is it possible that the 'abrasion' could have been from a previous unreported branch failure that impacted on that part of the trunk?

 

 

are skinks a protected species Guy?

Big tree, within falling distance of the pavement? The Kretzch would be a big concern for me.

"Is it possible that the 'abrasion' could have been from a previous unreported branch failure that impacted on that part of the trunk?"

 

David as you see below this brown scuffed bark is seen where physical damage can be ruled out.

 

These skinks are pretty common so they are not a legally protected species. But the client enjoys them visiting them in his garage, and says he has a 'symbiotic relationship' with them.

 

scots, I agree Kretch on red maple is a serious condition. I think 15' and 20% off is a proportionately serious treatment.

Assuming you are right on the fungi ID, and following the clients options, I would simply remove.

 

If it is KD there is little you can do to prevent catastrophic failure at some point in the future.

[treeseer]

The client's options include work to lessen risk of failure, and aid compartmentalisation. Monitoring the integrity of buttresses seems reasonable.

 

I've seen A. rubrum wall off Kd, and I've seen total failure. This one's been fighting it off for 28 years.

 

Have you seen this brown bark syndrome in the UK?
