Radical Restoration
Assisted Translocation/Migration
Translocation is not a radical idea
BUT, “assisted” translocation:
oPlan to get ahead of climate change
oPredictions from global warming is that the optimal habitat for most
organisms will shift
To get to cooler places:
Poleward
Higher in altitude
Deeper in waterbodies
Assisted Migration (AM)
oMost species are going to change their distributions in response to
global warming changes
oBUT the rate is likely to far exceed what organisms have had to deal
with before
E.g. boreal (coniferous) forest trees may face a need to move
10-20X faster than they ever have
oIdentify those taxa that are too slow to cope
Then move subpopulations of them ahead of time

Document Summary
But, assisted translocation: plan to get ahead of climate change, predictions from global warming is that the optimal habitat for most organisms will shift. Assisted migration (am: most species are going to change their distributions in response to global warming changes, but (cid:0) the rate is likely to far exceed what organisms have had to deal with before. E. g. boreal (coniferous) forest trees may face a need to move. 10-20x faster than they ever have: identify those taxa that are too slow to cope. Then move subpopulations of them ahead of time. Only single, high-valued species are likely to be translocated: rather than whole assemblages. Putting species into places they have never been before: novel ecosystems could arise. The impacts upon species/assemblages living in the destination: they may be coping ok with climate change up to that point. Common in both terrestrial and marine habitats. Reasons for moving: local to region rather than continental to global.
