Looking for sugar maple and beech seeds

I'm looking for sugar maple and beech seeds from the northern reaches of the natural range of these trees. That's probably somewhere in Canada. I would be willing to buy about a half pound of each. The forest in my part of Alaska is being devastated by global warming effects such as beetle kill, and I want to try to grow something that might survive a warmer climate. I'm not especially interested in a sugar, nut, or lumber crop, but I would love to leave a legacy of useful trees.

If nobody here can help you out, try these people:

They offer sugar maple, and beech seeds at reasonable prices.

I think I figured out how to answer on the discussion list.

Those are terriffic sites, thanks for the addresses. I think I remember enough Latin from high school to be able to find what I'm looking for. Maybe. I hope!

wish I had seen this a while back, hubby brought me a cup of beech seeds home from a dr appt this late summer, and I planted them all..sorry
