Jack London's Oak under Attack.

Not sure just how accurate this is but two pathogens are named here

Thanks for adding the link sean.

 

Surprising that a seemingly well regarded 'Heritage' tree is potentially being given up on without throwing a heap load of management at it.

 

Do you think it's the cost implication of ongoing management here Guy or pure risk aversion to the thought of failure?

 

 

 

A tree like this 'over here' would I'm sure have a plan that would involve bracing, reduction and soil work.

Thanks Taupo; I remember that Q velutina with the horrible form. The specs for Jack's tree are similar to other old oaks. It'd be interesting to see how your work comes out.

 

"Surprising that a seemingly well regarded 'Heritage' tree is potentially being given up on without throwing a heap load of management at it."

 

A heap load of assessment is instead thrown, always a budget for that! Their post-failure mgt was to whack 2 huge limbs near the house. A primitive sacrifice to the mysterious gods of nature, like tossing virgins into a volcano.

A little of the latter unfortunately; new managers tend to worry like that. Cost implications are exaggerated when the work is not understood, and most assessors here are far removed from pruning operations. So it's more the uncertainty than the cost. That's why I come to arbtalk, so I can refer to examples of the fine work done in the UK.

The oak is spared, thanks to a comprehensive assessment by UC Berkeley's Garboletto, who agreed that pruning works would manage the risk acceptably.

National Trust, take note!

That's great! Do you know how the tree was assessed this time in particular to come to the different conclusion than the 3 previous assessments?

Yes, the US leading the UK into the light, of veteran tree management. Isn't it ironic?

 

How was the assessment different? The main thing was, it was systematic, whereas the previous reports omitted some key aspects.

 

Here is his protocol: UC Berkeley Forest Pathology and Mycology Laboratory - Research

The collection process seemed quite invasive when it was first described to me. I have not sent in any samples.
