I am currently writing up a report on one in a high target area.  Most
likely to recommend removal.  There would be nothing left of the shape if
the top height was reduced.
I did a Resi test but did not bother with the sonic tomography.
There were other trunk issues and there was a climbing inspection.  Happy
to share and discuss with you if you message me.

I was going through a similar thought process over Christmas.
How many failures are there?
How much of an actual risk rather than a perceived risk is it?
Is there any data out there?

Countering that, what would it happen if there was a failure?
What would the inspecting expert witness have to say?
How would I defend this position?

To the point where I was going to post once I had completed the report.

Sincerely Tom

Dear collective,

Does anyone have experience of observing Cauliflower fungus on Scots pine
over a number of years or even better have tomograms or resistance drilling
measurements they can share (confidentially of course)?

I can think of maybe 3-4 previous times where I have formally recorded
this particular fungi over a 30 year period and the circumstances did not
warrant any further investigation. However, yesterday I recorded one on a
huge Scots pine (d: 116cm & h: 28m), which is within falling distance of
two roads and a house. The foliage/needle density appeared to be slightly
thinning compared to a neighbouring Scotty.  Also, I was somewhat surprised
to see the fruiting mass at this time of year.

I'm sure there will be others out there who have a better understanding of
this fungi than me and I'd be really grateful for any shared experiences
from the forum.

Many thanks in advance.
