Julian,

It all comes down to moeny, doesn't it?  Most ecological restoration stuff 
I've seen talks about re-planting with whips and waiting 100 years.  IOW 
minimal money.  And if the trees catch and you wait 100 years OK.  But the 
environment is much changes and who knows if all the associated crotters and 
plants and liches and assorted biota are the same at any point or at the end.

I think the "big bucket" suggestion may be the answer.  The really large tree 
moving folks I've talked to say the key is that the tree never knows it's 
been moved.  When I say big I mean >40" DBH.  Not the 18" tree at Meyerscough 
kind of stuff.  That big a move takes all the understor and soil  and 
associated biota with it.  Move enough of those units and you can move a 
whole woodland or hedge too I'd imagine.  But it costs lots of moeny.  And 
after care can be easily 1/3 of that big fat budget.

  It was the snails, and the scheme seems to have failed for lack of 
  maintenance, though accounts vary about whether or not the 'fixed' water 
  problem will allow the return of the snails.

  This is a common problem with moving ecologically complex sites around. The 
  maintenance plans may look good on paper, but keeping the practical aspects 
  up to speed requires monitoring, adjustment, and lots of time spread out 
  over years, and all of that means a commitment to fund it - never a big 
item 
  on the bean counters' spread sheet, once the project is signed off.

  There is quite a large literature in environmental impact assessment about 
  the problems of actually tracking whether or not the mitigation measures 
  actually worked.
