The reason is that in CMIP5 we test the version ​of the model used for future climate projections. Since OA and ESM models will be considered, depending on the model used the vegetation will be

 +There are still questions concerning the possibility to have a 6ka reconstructed vegetation from a combination of model output and data analyses that could be used for sensitivity experiments. Please tell if you are interested by such a map and what would be the best variables (pft?) that should be provided (see comment from B. Otto-Bliesner in the discussion pannel).  ​
