The semiarid Dry Gneissic – Schistose – Volcanic Hills ecoregion is shrub- and grass-covered and is underlain by Quaternary and Tertiary volcanics. It is less rugged and drier than the higher Barren Mountains (17e) but is more rugged and receives more precipitation than the lower Dry Intermontane Sagebrush Valleys (17aa). Its sagebrush-grassland vegetation contrasts with the open-canopied forest – shrubland – grassland mosaic of Ecoregion 17e. Grazing is the most common land use in Ecoregion 17ab.
