I have filled two cavities in the past few years , both coated with fire 
retardant foam and iron barred.
The justification has been to stop individuals setting fire the trees, yes it 
removes a habitat but then so does constant fires

cavity work?

As you say, it's very long and I've not listened to most of it, but what 
exactly is the PURPOSE of filling a cavity? It adds nothing to the strength 
and as Simon says, removes a bit of valuable habitat. There seemed to be 
something about 'giving the tree a surface to grow over', which surely is 
precisely the wrong thing to do. Rolls of wound wood are much stronger than 
'normal' tissue and would add far greater strength than a much thinner layer 
of tissue growing over a flat surface. Besides which, preventing air 
circulation within the cavity is likely to promote decay which, of course, 
one can't monitor once it's sealed behind layers of foam, cardboard and wire 
mesh.
I also wonder about the chemicals used in these foams and the vapours 
produced as they cure - methylene-diphenyl-diisocyanate 4,4 doesn't /sound 
/all that pleasant. (It's also highly flammable) These guys are obviously 
well meaning, but in the end it seems to be much more about people needing 
things to be tidy and to DO something, because of course the poor ole dumb 
tree can't look after itself.

May I have your comments please? It's longer than necessary; I just
jumped over a lot of it.
