Ecoregion sections of California deserts

The dataset delineates ecological sections within California deserts. These deserts occupy the southeastern portion of California and include two ecoregional provinces comprised of five desert regions ("ecological sections"; Miles and Goudey 1997). The American Semi-Desert and Desert Province (warm deserts) includes the Mojave Desert, Sonoran Desert, and Colorado Desert sections in the southern 83% of the California desert. The Intermountain Semi-Desert Province (cold deserts) includes the Southeastern Great Basin and Mono sections in the northern 17% of the region.
