Don:

Some of my ideas for increasing resiliency for climate change (remember
these come from a Minnesota perspective where increased drought and wind
are likely to be the biggest effects) include:

1. Reducing multiple stresses--for example we can control deer grazing and
thereby have one less stress on reproduction.
2. When seeding or planting seedlings, mix in some from the seed zone to
your south and let natural selection and competition among the seedlings
determine which survive.
3. Think about moving species one notch upward on a soil texture gradient
from sandy to silty. For example, red oak currently grows on sand and
loamy sand in MN, but in the future it may be better suited for loam or
silt loam.
4. Encourage drought resistant species: in MN these would be bur oak, elm,
hackberry, hickory, basswood.
5. To the extent possible, use species that are more wind resistant. For
example oak and birch are more wind firm than aspen.
6. Accept reality--you may not be able to maintain all species you have now
in a different climate.

Lee-
Thanks for taking the time to return post!
Prior to retiring, I was a vegetation manager for Grand Canyon NP, and when I wasn't tussling with the day-to-day push and shove, I tried to anticipate what might be responses of our restoration efforts to a changing climate.
Regarding #2, I was actively considering bringing higher seed zone (latitudinally/altitudinally) seeds, but I really like your suggestion to mix them with local seed zone seeds, and let the environment work out the answer.
Regarding #3, while our soils are very different of course, other gradients to consider come to mind (latitude, altitude, forest type transitions, bio-geographical ('sky islands'===> points and peninsulas ===>mainland) progressions).Regarding #4, we're currently in the 13th year of a 14 year drought, so 'introducing drought resistant species' is sort of an ongoing process...;>)
Your last is best, know when to quit!
-Don

ENTS:

Below is a link to a recently published paper on ecological changes and
coping with climate change. It is interesting and provides some good links.
