Admittedly it doesn't take much to trigger epicormics in Tixe, but I doubted 
myself enough to check a few sources before I said that. They weren't journal 
articles, just commonly held understandings by a few sources. In fact I 
settled on that wording because it's eactly what the Woodland Trust website 
says.

The damage might be pruning, it might be storm damage, and it may include 
stem decay such as K. deusta. I'm pretty sure it includes (ironically) 
epicrmic removal. Once you start removing, you've probably got to keep doing 
it. The stress could be anything but I'd like to narrow it down.

I was involved ina big survey las year in a public park, hundreds of formally 
arranged limes of two varieties of Tixe, which were easily separated. One 
variety was much more prone to basal epicormics than the other but what was 
very marked was that not all the susceptible variety were sprouting. I noted 
a correlation between sprouting and surface root abrasions/compaction but 
scientifically and statistically reliable evidence would require an 
impossible-to-know history for each tree.

One case closes and another opens:
"Epicormic growth in limes is usually a response to damage or stress."
Really?
I though is was simply a characteristic of Tilia x Europaea

Epicprmic growth in limes is usually a response to damage or stress. That 
is itelf is a trigger for a more detailed look at the tree by a competent 
inspector. Case closed.

<<I frequently get epicormics removed, for clients who have accepted 
well-rounded advice, and epicormic removal can cost as little as £10 a 
tree.>>

"Well-rounded advice"?

You've sketched out a text book example of hazard focused, risk-averse, 
base-rate neglect, risk entrepreneurship.

I particularly enjoyed the QVC shopping channel sales of pitch of, "Why 
not avoid forking out £250 000 for a claim when epicormic removal MAY 
save a life at a cost AS LITTLE as £10 a tree*?"

How about loosening your clients purse strings bit more by making the 
life that might be saved that of a child?  Even better, adding a 
possessive pronoun could help maximise the fear.  'Your child'.

Here's the reality, to establish some all-important proportionality.

Compared to other everyday risks that we readily accept, the overall 
risk to us and our property from tree failure is extremely low. The 
annual risk of a death or serious injury is less than one in a million. 
Given the number of trees we live with, and how many of us pass under 
them each and every day, being killed or injured by a tree is a very 
rare event.

That's for all trees.  Let's try to establish a base rate for Lime with 
epicormics and Kretzshmaria duesta.  Say, over the last 10 years.  How 
many Limes were there with epicormic growth, which didn't display 
obvious defects, and hosted Kretzschmaria that produced fruit bodies 
which could only be seen if the epicormics were removed, and resulted in 
so much decay it caused the tree to fail, and then killed or seriously 
injured someone?  We can already figure out the risk is much less than 
one in ten million.  Shall we just stop there?

Costs may vary, and "…the prospects of reducing the risk from tree
