The reason I ask this is that if you're trying to build a long-term prognosis for a tree and it turns out that it is, say, at the southern edge of its range and we expect that climate change is going to cause the Ottawa area to become warmer, then it would be harder for it to survive. However, if this is a tree that is close to the northern extent of its range, that doesn't necessarily mean it has a dismal future on the basis of climate change.
Does that sound like a reasonable thing—
