The following plant index will focus initially upon native species around the Columbia Basin Plateau characterized by a shrub steppe environment in BSk climate classification. As we learn more and share information with our guests this list is expected to grow to include the Great Basin flora of Utah, Nevada, SE Idaho, New Mexico, Colorado and Eastern California. It is important to note that species from around the world in similar BSk, BSh climates will join the roster; Afghanistan, Uzbekistan, Argentina’s Patagonia, Kazakhstan’s Kazah Steppe region, Eastern Spain and Mongolian shrub steppe and others.
