Thank you to all who have responded, very helpful.

I was on site again today for another look, and have catogorised it as a U.

In the short term the client will be reducing it to a monolith (subject to
Natural Resources Wales bat approval etc), and then hopefully in the spring
will be looking to get the bats rehomed into a bespoke structure before
removing the monolith altogether.

All the best,
Bettina

Bettina said the tree was bristling with Ganaderma conks, and it had just
shed a large branch across the road.

I'm not sure you could remediate these faults short of turning it into a
monolith and whether that's remediating anything is moot. As it happens I
first monolith-ed a Beech tree about 35 years ago; I don't think it
lasted
even 20 years before it was deemed it had to be removed. In fact there
are
quite a few monolith-Beech in Ecclesall Woods and none of them look
likely
to be anything but soil-biomass 20 years hence. So all in all I think
suggesting that Bettina's tree is likely to survive for 40 years is
extremely optimistic. Thus it can't be category A3. Or anything other
than
U.

As for the LPA sticking a TPO on it, a TPO is not the right way to
protect
a bat roost. And if the LPA wanted some particular management course of
action, then they really ought to be funding it, but in Sheffield they
simply wouldn't get involved, no matter what the Politicians said and
what
the Ombudsman might have recently told them to say....

Bill.

Dear AllBased on the information presented the tree would (in my humble
opinion) fall neatly into the U category.That's until Bat roosts were
mentioned. That would bring a further determination regarding Bat
species,
sex and numbers of bats. For example if it was a maternity colony or a
relatively scarce bat the focus might go there. If we were dealing
with a
small number of Male Soprano pipistrelles occasionally using the roost
it
maybe the tree could be felled after bat inspection/licensed.For the
more
complex bat roost parameters,  an alternative bat roost feature maybe
required to be installed before felling takes place or the tree
structure
altered to make safe any wayward branches with as least disturbance to
the
bats eg undertake works when the bats are on holiday....  done under
licence.My take on the matter is that Safety comes first.But there you
go.DavidSent from my Samsung Galaxy smartphone.

  in it? It depends on the context.  If the tree can be retained in
some
form with a low probability of harm then it could be classed as an A3.
This might necessitate some change in the design of the development, if
that is possible.  Otherwise it may have to be a U.  The LPA may
disagree
however and demand its retention.Mike Charkow Arbor Vitae Arboriculture
