The Magic Valley ecoregion is underlain by alluvium, loess, and basalt flows. Its aridic soils require irrigation to grow commercial crops. Many canals, reservoirs, and diversions supply water to its pastureland, cropland, and residential, commercial, and industrial developments. Small grains, alfalfa, sugar beets, potatoes, and beans are grown. Livestock and dairy farms occur; dairying is more common than in Ecoregion 12a. Dams, irrigation diversions, pollution, and channel alteration have affected water quality. Over-watering from sprinkler- irrigated portions of Ecoregion 12g has raised ground water levels and created artificial wetlands. Natural vegetation is mostly sagebrush and bunchgrass but low terraces have salt tolerant plants. Population density is greater than in the rangeland-dominated Ecoregions 12g and 12h.
