Mountain Home Uplands

Ecoregion on Columbia Plateau, ID

Generate High-Quality PDF

The Mountain Home Uplands ecoregion is arid and shrub- and grass-covered. It is mostly rangeland and is sparsely populated unlike Ecoregions 12a and 12i. Local relief is between that of the flanking foothills and the Magic and Treasure valleys. Mesic soils are common and are warmer than the frigid soils of Ecoregion 80a. Today, cheatgrass, medusahead wildrye, and sagebrush occur and stock carrying capacity is low; native grasses are much rarer and vegetative regeneration capacity is more limited than in the cooler Ecoregion 12g.
