Thanks TC for the link,.
That's a very interesting animation of the change.
In Canada, they've been working on a model based on where trees are growing. 
It doesn't matter if it is a native, naturalised or some import plunked down 
on a homeowner's front lawn. If it is growing happily, then the zone is at 
least that of the tree's.
I garden in area that used to be Cdn Zone 5b (add one for you southern 
neighbours to get USDA) but I'm reasonably confident we're tipping 6b. White 
spruce, a coniferous mainstay, is now showing signs of stress during the 
hotter months. We're losing some of the northern chappies but the Carolinian 
crowd are making a comeback. Win some, lose some, I guess.
