Hi Wayne,

That is interesting - do you know of any research that has shown saprophytes 
to consume tree bark?  That was one of my main concerns.

Ivy tends to promote and maintain a higher humidity in such
micro-environments, so perhaps its removal might discourage fungal
development. Closer examination might reveal useful particulars. Sometimes
saprophytes consume the bark, setting up conditions for entry into the
heartwood, as well as set up conditions for parasitic species. Even loss of
heartwood weakens the tree, which can appear to the casual observer to be
"perfectly healthy."

I am speaking from experience in the USA only. Even in the relatively dry
climate in which I live now, I have observed such phenomena in association
with ivy. Some species appear to be more tolerant than others. In
susceptible species, failure is often the result, even of those "perfectly
healthy" ones. Any tree professional should perform all of the necessary
investigations to secure as complete as possible analysis. (No offence to
my UK listserv pals, but failure to follow those procedures seems to be
more common than not here in the USA.)

I think this is some form of dry rot - do you agree? It was growing on two
Lime trees under ivy. I didn't find any bark necrosis, though one tree has
a small amount of sapwood delignification (possibly unrelated). Does anyone
know the effects of this on trees?
