One variety of red spruce, especially chosen for its origins in the mountains of West Virginia, will become a test
I remember years ago reading that the climate of Vermont in 2100 was expected to be similar to Virginia or Maryland in 1900.
Also about 20 years ago, I was talking to one of my father's old Air Guard pilot buddies who had started a very successful business selling maple syrup and other VT products. He had ended up on the board of some maple research lab and he said they were worried about a future in which sugar maples couldn't grow in Vermont. Most maple syrup production is in Canada already, but VT is the largest US producer and it's pretty important culturally.
Meanwhile, in this neck of the woods (so to speak), they are looking at assisted migration of sequoia trees, though it's not clear where they would go. They do know that thousands of years ago, when the climate was different, they had a much wider range and it looks like there's a good chance they will not survive the next couple hundred years (I think we lost 10% of the total just last year or the year before and we're talking about trees that take a thousand years to replace). So even with assisted migration, we might have a period of centuries upon centuries without truly giant sequoias or with very small numbers of them.
