Hi Bettina, what size/ dbh is the tree; does it show signs of having 
responded by regrowth to the previous pruning work; what level of target does 
it have currently- in terms of the busy-ness of the road, and whatever the 
proposals are for the development?
As Jim says - more questions rather than answers.... any photos??
If the bat roost is in the main stem, then  if nothing else a monolith would 
be worth trying, dismantling as a crane job using bat-friendly contractors

Dear All,
I have a mature Beech with many Ganoderma fungal brackets around the base and 
up the trunk, numerous old pruning wound cavities and other veteran features, 
and an identified bat roost in it as well.

It is within a site requiring a BS5837, and yesterday shed a very large limb 
across the road.

Question - would you class this as an A3 tree, or as a category U?

Many thanks as always,

regards
Bettina
