There's no doubt whatsoever that projected rates of change are far greater than natural processes can accommodate. Maintaining adaptedness in plant populations will require the assistance of mankind to transfer the appropriate populations of the appropriate species to the new location of their climatic optima. Assisting migration, therefore, is only a part of the managerial options. Maintaining adaptedness, particularly in trees, will require us to participate in the evolutionary process; we must be willing to provide the fuel for speeding up the process of selection.
In forestry, the information is available for providing appropriate guidelines. However, I am not aware of current reforestation, rehab, or conservation programs that are targeting climates of the 2020's. The closest that I know of involves the effort of researchers to find a 'home' in British Columbia for populations of California's Brewer spruce, a species classified today as threatened.
