Himmler estimated Aryanization of the region would take twenty years, first expelling all the undesirable populations, then re-distributing the territory to appropriate Aryan populations. In addition to changing the demographics of the region, Himmler also intended to plant oak and beech trees to replicate traditional German forests, as well as plant new crops brought back from Tibet. To achieve the latter end, Himmler ordered a new institution set up by the Ahnenerbe and headed by Schäfer. A station was then set up near the Austrian town of Graz where Schäfer set to work with seven other scientists to develop new crops for the Reich.
